Who is the bad guy that you most despise? *This might contain spoilers though.*

Who is the bad guy that you most despise in the Fire Emblem series, and why?

Alright, who are the bad guys that you want to get a piece of so badly?

FE1-Moses-Because he killed Marth and Ellis' mother and that he took over the Aritia kingdom, as he is also a faithful servant of Medeius.

FE2-No comment.

FE3-Book I-Moses. ^See above (FE1).
Book II-Medeius-He was behind everything in this book and that he possed and lived inside Hardain's body for years,took over the Akaenia army and turned the continent into hell to bring forth revenge upon Marth and his friends.

FE4-Possibly Trabant, though it wasn't really his fault for the death of Leif and Altena's parents as he was manipulated by Alvis, but still he was downright despicible for raising Altena when HE murdered her parents, Altena strives for revenge once that she finds out.

FE5-Beldo-Because he turned Eyvel to stone, I loved her.

FE6-I can't say Zephiel because he was mistreated very badly by his father, though he did turn the continent to hell. But for the guy I most hate in this game, it would be Oro as he is a sniviling lying cheat and that he is certainly no holyman as he oirdered his men to kill those who worships St.Elimine.

FE7-Sonia-She was heartless. She killed Nino's parents.

FE8-Calleh-He killed Ismire, Joshua's mother.

FE9-Ashnard-He turned the continent to hell, killed Elincia's family, tried to destroy the world with Feral Dragon's as Nasir explains in FE10. Kills anyone who fails their duties, this war he starrted was all for releasing the goddess from the medallion so that he can inhabit her power. Though he was tricked by Sephiran (Lehan) into waking the goddess of the medallion, but he did this plot to have that all for himself, and that he killed his father to claim the throne.

FE10-Lekain-Because he tricked Micaiah into starting a rebellion, as Micaiah didn't know that the curse of the blood pact can be broken by tearing up the contract itself. Because of this rebellion he has costed millions of lives of Gallia, and Daein, he also corrupetd an entire nation (Begnion), he is the cause of everything in this game, the release of the goddesses and the diciples of order, and that he also burned the Serenes Forest and framed Sanaki for it, endangered Naesala's people, and that it is absolutely gratifying when Naesala or Tibarn initiate a battle conversation with him as well as Micaiah and Sanaki.

Weeeeeeeeeeee~
Here are mine from the ones I've played...

FE3: The shadow Orb's weird living entity magic complex plot device. It takes complete advantage of humanity's (in this case, Hardin's) negative traits. I HATE embodiments which represent how fucked up the human race is. I mean seriously, since when does failed love lead to being brainwashed?

FE4: Shagaal, the baron of Agustria. He killed his own father for the throne, and slayed one of my favorite characters as a bonus. Burn in hell, Shagaal.

FE5: Reidric, for being the knocked up haughty villain who in reality was a coward. What is he, Elliot Spitzer? Nah, Spitzer had a prostitute ring...

FE6: I blame the entire dragon race for their maltreating of Idoun. That was purely unorthodox.

FE7: Erik.  Once more, I hate haughty lords who have a superiority complex and yet are snivelling cowards.

FE8: Riev. I believe the words "creepy sadistic satanist" sums him up pretty well.

FE9: Tough choice here... I would have to say Petrine. I despise her for her discrimination towards Laguz, her superiority complex over the great Ena, and how she was only pure evil and chose to be a subordinate of Ashnard due to her fear of being discovered as a Branded. She refuses to accept her fate and instead seeks a doorway out into acceptance. She gives Soren and Down Syndrome girl a disrespectful reputation!

FE10: Izuka: Lying. Cheating. Selfish. Lowly. Punk.

I despise her for her discrimination towards Laguz, her superiority complex over the great Ena, and how she was only pure evil and chose to be a subordinate of Ashnard due to her fear of being discovered as a Branded. She refuses to accept her fate and instead seeks a doorway out into acceptance. She gives Soren and Down Syndrome girl a disrespectful reputation!

As far as the most contemptible FE character I really have no opinion, they're all kind of two-dimensional. But I wanted to know when there is any dialogue which hints that  Petrine is Branded? I haven't gotten all of the support conversations, but I've never come to that conclusion. Interesting as it is though...

There is no support coversation which says so, you must have Soren attack her in Ch.23. She mentions that he's no spirit charmer (reffering to the mark) and that he's "just like her." There's also some point in FE10 that Petrine is mentioned as branded, I believe.
