It's always interesting when Zell's around... He remarks on just about everything and either clashes with another character, or is the brunt of some joke. While he does get angry quite easily, he also cools off quickly. The only grudge he holds is one for Seifer, which really can't be blamed.
Zell tries very hard and when he doesn't succeed, you have to feel pity for him. ^^; He's never early enough to get a hotdog from the cafeteria, and being a SeeD, I think he deserves one. He doesn't think just of himself, though. When Rinoa asked him to forge Squall's ring for her, he agreed (at no cost to Rinoa ~_^). He even participated in Selphie's band when the Garden Festival couldn't be held.
Throughout the game, Zell is a good friend and comrade to the other characters, even if he gets along better with some rather than others (...Irvine). His intentions are honorable and he is completely devoted to the sorceress mission. Zell's always ready and willing to help. ^_^
