This is something that I've to disagree with. For a lot of S1 Kaiser's character could almost be summed up as "FAVAROOOOOO" IIRC. Good riddance.
He had other qualities too. Like constantly falling.
In all seriousness, I won't deny that Kaiser wasn't exactly a good character ever, but I liked his relationship with Favaro and he was generally fun to watch. He was fine for an extravagant interpretation of a chivalrous noble. In S2, he's pretty much defined by his indecisiveness and his poor acting. He's finally a knight, and a captain, but he seems like a loser 99% of the time.
