Basically a glimpse of the components of the fusion and fusion himself. Cho is a fusion between my OC T-H30 and Yamcha made in the lab as an experiment, both parties agreeing to taking part into this. However, people making this fusion weren't exactly at a good place mentally, so they created something that isn't exactly "good" in a sense.
Cho is kinda of villainous in a sense, since he's selfish and all for himself (also Van Kleiss influences because I kept listening to his theme on loop and it's just so good and idk, but it just fits Cho, both voice and personality, since he sees himself highly, given that now he has both strength and intelect.)
Also for reference, Yamcha and T-H30 in case y'all wanna have a "clearer" picture of who made the fusion.
