I was thinking of translating Hojo's laugh as "Uweeheehee!", just like Kefka, but Kefka's laugh in Japanese is "ヒッヒッヒッ!". I thought it was a good idea, because both are insane characters, and But I guess I'll translate Hojo's "クァッ クァッ クァッ!" as "AHAHAHAHAAAA!". Not sure if it'll cause the same effect.
