Most difficult Fire Emblem boss, in your opinion. *Spoilers*

[Ashnard]

I was muddling this over the other day, trying to think which FE boss was the most difficult, at least, from what I played (FE 4, 6-10). I can't be all to sure, though, but let's just say for converstation's sake that you are fully equipped to tackle whatever boss you are about to face (ie. Black Knight with Aether, Yurius with Narga, etc.) Here's at least what I came up with:

FE 4: Yurius- Not that tough. I had an unpromoted Yuria take him down with Narga, because it's too good.

FE 6: Idoun- Not tough at all. Two hits with Sword of Seals, and the fight is over. One if you critical...

FE 7: Nergal/Fire Dragon- Both are taken out pretty quickly by the lords, but I did have trouble with the Dragon at first.

FE 8: Demon Lord- Easy as Idoun. Really, 8 different weapons that deal serious damage to him? That's a bit much.

FE 9: Black Knight- Pound for pound, this boss has Ike beat. A lot relies on luck; getting Aether, NOT getting hit by Luna, and so on. I've heard the battle is alot easier if you use Resolve and Nihil, maybe, but I have yet to test that. Fairly difficult.

FE 9: Ashnard/Possessed Ashnard: Ashnard, not so much. Aether takes him out pretty quick. Hard mode Ashnard...Definately more of a challenge. If Aether doesn't activate, you have a long battle with several physics being used. The Laguz kings make this fight a bit easier, though.

FE 10: Ashera- Probably the hardest FE boss to date in my case. With her long range attacks, AOE attacks, and a very annoying Aura to bat away (that reflect ability is to blame), she takes alot longer to defeat. Not to mention, if anyone other than Ike defeats her, she revives.

So, that's my take on it. I know FE 5 is insanly hard, and I've heard alot about Medius/Mediuth being fairly difficult, so I can't say for sure which boss is toughest over all. What do you think?   

[hyde]

While FE5 itself is hard, the final boss, Veld, is pathetic. Not much of a battle, really.

I'd also say Ashera is the most difficult boss, if not only for the fact she can basically attack all of your units, including your healers.

[Art]

All FE's? Okay. Let's see...

FE7: Nergal: A couple of hits of Aureola took him out. I'd say he's really easy.
Fire Dragon: Also got taken out by a few hits of Aureola, though I had trouble with him at first because he almost killed my peeps quite a few times before I found a good strategy.

FE8: Demon King: He was a little harder since he kept summoning all those monsters to do the dirty work for him. Duessel actually died in my second playthrough via a critical (and I lost Garm because of it, too. )

FE9: BK: Seriously? This fight was rigged. Massively. The fact that I left Mist at level 3 unpromoted didn't help matters much, either.
Ashnard: Not so difficult, I guess. A few hits from random people can finish him off.
Possessed Ashnard: Can't say. I never did beat PoR on Hard.

FE10: Ashera: My God that does not exist, she was hard. The AOE attacks are annoying, the whole barrier thing was a little messed up, that skill that her barriers have is a bitch. (Half the damage you inflict getting returned to you? Seriously.  ) Still, it was hard in a rather fun way (Though I had to Battle Save so I could restart a million times when Ike attacked Ashera since he only had a 41 percent chance of hitting her. What can I do?)

So I'd have to say Ashera was the hardest FE boss ever.

FE 9: Black Knight- Pound for pound, this boss has Ike beat. A lot relies on luck; getting Aether, NOT getting hit by Luna, and so on. I've heard the battle is alot easier if you use Resolve and Nihil, maybe, but I have yet to test that. Fairly difficult.

Although the combo works in theory, it's impossible to have. You get the Resolve scroll in the very chapter you fight the BK, so you don't have the opportunity to give it to Ike before the fight.

[(／_^)／ ● ＼(^_＼)]

To be fair, I would say that Yurius is harder than Ashera when not using Yuria. Yurius doesn't take much damage because of his Loputousu's tome ability, and when Wrath kicks in, you are only able to use Lakche, Skasaha and Celice. Then again, there's no reason for not using Yuria.

[Lord Fuckboy]

Ashera is a joke when you have the Fortify Staff.  When you don't is a cmopletely different story.  Following Ashera without Fortify is FE9 Black Knight without a decent Mist or Wrath/Nihil.

[YokaiKnight]

FE 7: Nergal/Fire Dragon- Both are taken out pretty quickly by the lords, but I did have trouble with the Dragon at first.

For the Fire Dragon, Luna'd Athos works wonders. if you get lucky with Filia's might, you can finish him in one turn. 

FE 9: Black Knight- Pound for pound, this boss has Ike beat. A lot relies on luck; getting Aether, NOT getting hit by Luna, and so on. I've heard the battle is alot easier if you use Resolve and Nihil, maybe, but I have yet to test that. Fairly difficult.

You get Resolve that chapter, so you can't give it to Ike.

Wrath+Nihil only has a good shot if you can have him attack below half health--otherwise, he won't have enough opportunities to critical. At least, that was why I phail'd when I tried that combo on him. It's best to just hope for Aethers. I also give him a seraph robe--with max DEF and more than 52 HP he can survive a regular hit+Luna.

Mist is also necessary unless you have really good luck. She can finish that stupid Bishop too.

FE 9: Ashnard/Possessed Ashnard: Ashnard, not so much. Aether takes him out pretty quick. Hard mode Ashnard...Definately more of a challenge. If Aether doesn't activate, you have a long battle with several physics being used. The Laguz kings make this fight a bit easier, though.

Even regular Ashnard can be a headache in Hard Mode, because of his movement--you likely won't be through with all the enemies before taking him on. Thanks to his lame speed though, many people can survive a hit from him.

Possessed Ashnard is annoying, but like the rest of the chapter Fortify proves to be a godsend (or the Ashera Staff if you're in a pinch).

[Lord Fuckboy]

Oh yeah, I also forgot how Ashnard cannot be ganged up on except by like three people; Laguz general, Ike, and dragon.  He's a bitch to fighter regardless of possessed or not for that sole reason, and he can 2HKO Ike as soon as he goes apeshit.

[Haken]

Here's my two cents on the matter...

FE1: Starlight + Aura +Falchion= Easy win. Xcalibur isn't too bad either.

FE 3: Isn't Medeus supposed to die in one hit from Falchion? I sort of gave up after Hardin....

FE4:

To be fair, I would say that Yurius is harder than Ashera when not using Yuria. Yurius doesn't take much damage because of his Loputousu's tome ability, and when Wrath kicks in, you are only able to use Lakche, Skasaha and Celice. Then again, there's no reason for not using Yuria.

I never really found it that difficult even without Yuria. Celice with a strength ring is able to do 5 damage to him (with tyrfing that his) and if he has maxed skill + the skill ring, he would have a hard time missing. The only really annoying thing about Yurius was that jackass Meteo tome which kept sniping Sety and Altenna....

FE5: Said and done. Honestly, for so many tedious levels, the final boss was  a serious dissapointment.

FE6: Also said and done. Even if Roy is virtually 1/1, you could always use Fa.

FE7: Nergal is utterly vanquished by Aureola, even with Renault using it. The lords easily smite him as well.
Fire Dragon: You could have all your units unpromoted, and Athos could finish the battle for you with repeated healing/elixirs and casting aureola every turn. You would kill him in 6 turns.

FE8: Everyone knows this was the least challenging FE game yet, unless you used some all Jeigan team, and even then, the twins easily wipe Fomortiis out (if Myrrh doesn't do it first).

FE9: Meh, BK's Luna is stopped by a full guard. After that, it's easy pickings. Ashnard was annoying in Hard Mode since he actually moved and could do criticals, but if you cornered him with Ike, the kings and Nasir/Ena, he wasn't THAT much of a challenge.

Oh yeah, I also forgot how Ashnard cannot be ganged up on except by like three people; Laguz general, Ike, and dragon.  He's a bitch to fighter regardless of possessed or not for that sole reason, and he can 2HKO Ike as soon as he goes apeshit.

Agreed, but that's what staves are for. Although him three shotting Giffca and Naesala was really annoying. 

FE10: Yeesh... Ashera would have been bearable if only she didn't alternate between attack types. One single long range attack was enough to instant kill my heron. 

[Neofox]

Thanks to [Ashnard's] lame speed though, many people can survive a hit from him.

How is 28 speed lame?

FE9: Meh, BK's Luna is stopped by a full guard.

The Full Guard negates effectiveness bonuses, it doesn't negate enemy skills.

[YokaiKnight]

How is 28 speed lame?

It's lame because I have a faulty memory and though he was slow for some reason.

[Celice]

Am I really the only person who didn't have trouble with Ashera, like, at all?  hit an run the barrier, and then wipe her out.  The spirit thingers were complete pushovers and were no threat; heal and repeat.

Or my AI was broken or something >.>

[Ice Dragon]

I had no problem with Astarte, either. Her field attacks are easy to anticipate (I think they also follow a set pattern (physical, magical, silence, repeat), though she only got to use four before she died, so I can't be sure), so you can just put people on the correct squares in preparation. The Spirits were a joke. The Aura skill is easily taken care of with four units with Grasp (Nihil) (max Strength Ike, Wayu, Nephenee, and Vize can easily take out one per turn).

Ashnard's movement range is no problem. Simply surround him with 4 characters that can take one round of combat. Sure, it makes the battle longer (since you won't do damage on a counterattack as he'll likely attack someone who cannot return damage), but you don't have to worry about him moving anymore (and you can use regular Live (Heal) staves and shove the healer out of Gurgurant's range instead of Reblow (Physic)). The only problem I've ever had with Ashnard is that his berserk mode Speed is enough to double a half-transformed untrained Nasir.

As for the rest, Fodeth is an utter joke, Nergal is easily killed with Aureole, the dragon can be killed in one turn with the lords and Fala's Might (and Athos if your lords aren't good enough). I no longer remember Zefhyr, Idenn, or Mediuth (FE3 Book 1).

I personally think hoardes of generic enemies with nearly on-par stats compared to your own units cough Micaiah chapters cough are far harder than any of the final bosses (as you can get attacked by many more units in one turn and can't heal in between).

[Cooked Mongoose]

yeah, ashera was pretty tough, but i didn't really think she was...difficult. i think i got her in 5 turns on normal. but maybe i'm just too cautious XP (haven't even dared to try maniac ~_~)

as far as all other FE bosses i've faced, i think the hardest was ashnard on hard. it wouldn't be so bad if he didn't darned go and chase you around once you got into his range ~_~ and darnit all since he goes around and targets units other than ike. otherwise it's just a whole lot of reyson and a whole lot of physic staffs.

maniac ashera though, i'd say would be the most intimidating. ....in fact, maniac mode in general.

[Ashnard]

Hehe, I can agree that Ashera on maniac sounds like a nightmare. Though fortify is the fight's godsend, I can imagine Ashera doing such massive damage on Maniac, with AOE and her long range attacks. In terms of difficulty, I'd have to rate Ashera first and Berserk Ashnard second (Eh hrm...I am NOT being biased, now...ok?). Black Knight fits in there as well, but I should be limiting this to purely final bosses, otherwise, one could easily say "Eltoshan/Fargus FTW" or something along those line, hahaha!

By the way, has anyone completed Fire Emblem Gaiden here? I want to make sure each entry is getting recognition, but I have no clue if Gaiden's final battle is difficult or not.

[chaosprophet]

 Considering the boss alone I think Ashera would be the strongest one (from the ones I played: 6,7,8,10). The other UBER bosses that you had to fight in other games, like for example, the red dragon had a major weakness: they just stood there without moving, so you could just take your time to kill them. But while Ashera don't move too she attacks all of your chracters so you can't just take your time... even fortify and that staff to repair itens have limited uses.
   But if you consider the whole chapter I think Nergal is pretty difficult too. You had too fight many powerful enemies that are using most of the better weapons of the game.

[Neofox]

As for the rest, Fodeth is an utter joke, Nergal is easily killed with Aureole, the dragon can be killed in one turn with the lords and Fala's Might (and Athos if your lords aren't good enough). I no longer remember Zefhyr, Idenn, or Mediuth (FE3 Book 1).

Idoun and Zephiel can be one-shot by a critical with the SoS and a Roy with decent strength. Medeus in FE3 (either book, but particularly book 2) is more annoying than difficult, as Marth criticals him easily. You just have to be sure to either kill or recruit the princesses surrounding him in Book 2 to prevent him from healing himself and living more than one turn (since having to deal with any earth dragons during the enemy phase is most definetly going to be less than pleasant...).

EDIT: Wait, who's "Fodeth"?

[Somewhat Overcooked Cheese]

EDIT: Wait, who's "Fodeth"?

Fomortiis would be Fodeth

[camus the dark knight]

FE1 Medeus: Somewhat difficult, only the Falchion can hurt him, and we all know how good FE1 Marth is...

FE2 Doma: Only did him once, didn't seem to hard, again only the Falchion can hurt him, but Alm isn't too bad.

FE3 B1 Medeus: He can be harmed by other weapons now, but only up to 5 damage max save the Falchion (10 max), but he has 0 luck, so it's easy to critical for 15, and 0 AS so he's easy to double. Not too difficult, but can be tough if your characters didn't get good strength since he's on a throne and thus heals.

FE3 B2 Medeus: Book 1 Medeus minus the throne, Chiki can also hurt him for 10 with max strength. Only difference is he can eat the girls to recover but that is easily avoidable by recruiting them or killing them before he does. (now the chapter itself is another story... quite luck based)

FE4 Julius: Narga rapes him, Celice+STR Ring+Tyrfing and supports kills him only slowly. Shannon+Balmunk+STR Ring+Supports, Faval+Ichival+Strength Ring+Supports... yeah you don't need Narga, he's manageable without it, but since we are just going for beating him, why wouldn't you use Narga?

FE5 Beldo: Think Nergal on a throne with even worse AS and no way to counter.

FE6 Idoun: Sword of Seals says 2 shot, 1 hit KO if a critical.

FE7 Dragon: Fala's Might+Luna+Athos+Speed Ring = 1 hit KO with a critical, 2 rounds without one.

FE8 Demon King: Tana+Vidofnir+Critical+Pierce= 1 hit KO

FE9 Ashnard: Lure out with Ike or someone, circle him with units that can harm him, use libro and attack until he dies.

FE10 Ashera: Kill the aura's quickly, use reserve when needed. Proceed by killing her with whoever and have Ike land the final shot with Ragnell.

I thought FE1 Medeus was hardest, but that's probably since my Marth was awful every time I played.

Oh yeah Doma can also be harmed by drain, but that has only 50% hit rate and isn't too powerful.

[UchihaHunter]

I'm going to cosign what Camus says on this...I've beaten FE10 in each mode, and you can freaking one-turn kill Ashera if you wanted to on easy mode, and 2 turn kill her in each other mode.

Ashnard is only annoying because only 3 units can harm him, but you could just uberize your dragon and completely rape him.

Julius is rough without Narga, but still entirely possible.  Plus, since you're playing to beat the boss, you'd have Narga anyway...

Idoun = Fail, although, not as much since the other holy weapons can't do effective damage to her...

FE7 Dragon = Fail, due to Athos + Luna

Demon King is a joke

Beldo...my roommate beat him with Mareeta and a broken Iron Sword...

I've yet to play FE1-3, but I can't imagine it being too hard...

Out of the ones I've played, I guess I'd say...Ashnard just because he can move and resurrects in HM and Maniac.
