Ugh, I think Cyan is one of my least favorite characters. He's just too slow; I can't stand waiting for his high level Sword Techs. Though, Dispatch is very nice early in the game.

I've seen a couple people mention how good Edgar's tools are, specifically the Drill and Chainsaw and how they can do 9999 damage. The problem with those tools is that they do 9999 damage only once and to 1 enemy. I'd much rather do more than 10000 damage to a single enemy (gengi glove/offering or just one of those) or 9999 damage to multiple enemies (Ultima). That's much more useful, I feel.
