One of my favs is Volt because hes brawler that actually respects other brawlers and bakugan.
I liked Volt too until the episode he battled Gus. He told Volt that what he was doing was wrong but he wouldn't leave the Vexos. Than he acts like he cares about Brontes when he's helping to kill him.
I think of Volt as one of those "I don't want to be evil, but I don't know what else to do" things. He seems like a pretty honorable brawler, but unless the Resistance convinces him to join them (which they're probably not- Although it would get rid of Baron...), he has no real other choice.
