Let's see what I can dig up...
"You're strong, reliable, ... and slow! You're the one, hands down! Hahahaa!" - Alec (to Arden)
"Hrmph. I can live with the strong and reliable part, but leave the slow bit out of it, ok?" - Arden (back to Alec)
"I am Glass! The gods fear my name!" - Glass
"Craven cur!" - Eliwood
"Big words make my head hurt!" - Bartre
"Behold! A giant walks among you! My defense is impenetrable! Come! Break your weapons against me!" - Wallace
"This is a message from Lord Nergal. 'I await you on the Dread Isle.'" -Denning
"Thunder! Thunder, hear my cry!" -Aion
"I won’t give up... Not here... Not in this place... I’ll keep going, even if I have to crawl..." - Innes (death quote)
"You don't look particularly sorry. You look rather pleased with yourself." - Moulder (to Colm who has set his package on fire)
"Where there's life, there's hope." -Brenner (whoops, wrong game)
"Bah... I am in NO way inferior to this so-called Demon King."-Innes (final battle quote)
I vote for this one:
"I am Glass! The gods fear my name!" - Glass
