Nall from Lunar and Ruby from Lunar 2. Nall just had an annoying voice, and Ruby was always getting in the way. I'd always be hitting on Lucia and then Ruby would intervene and act all defensive and say stuff like "That's my man!" Pfft, shut up Ruby. You're a cat/dragon/fluff/ball thing and she's hot, get the hell out of here.
Wakka was pretty bad, but Bender did his voice so I was willing to allow it. Talim pisses me off too. I'll probably think of more later.
