Cyborg (Teen Titans Animated Series) vs Ken Kaneki (Tokyo Ghoul). If you have a UniVS template with a picture of the two to replace the pictures, feel free. Comment your opinion on who would win and if you'd like to see this as an episode.
Both are men that went through life threatening accidents that required surgery. After the operation, they found themselves being half a man, Cyborg now being half machine, and Kaneki becoming half ghoul. They both struggle to maintain their humanity and keep from giving in to their other half. I bet you're asking why I'm asking for animated series Cyborg, well it'd be easier on Leo's eyes, and is without a doubt the most popular incarnation of Cyborg, also because Cyborg stomps if you use a composite.
Cyborg has a massive advantage with speed, but Kaneki has shown instances of greater durability and destructive capabilities, he's also shown to be a combat genius. I think that with his more useful powers, such as a quick acting healing factor, Kaneki can take this. In the end, Ken Kaneki will prove he's the better half-man.
