Phoenix Wright (Ace Attorney) vs Makoto Naegi (Danganronpa). 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.
These two are from visual novel games where the main feature is debating to find the truth. They each participate in murder trials, trying to find out who the killer is. Most of the murders they've had to solve have been overly complicated, sometimes enough for them not yo be able to solve them alone. Their game series have some odd characters like like angry gangsters, perverted chefs, and snobby richboys. Also if you're wondering why I'm not using Hajime Hinata, that is a massive stomp in his favor since at the end of his game he gains all of Izuru Kamukura's talents.
Now this can't exactly be a normal fight, it would have to be more of a trial where they both try to find the truth, with the losing being "punished" like in Danganronpa. Although Phoenix usually just comes up with random theories that just turn turn out to be right, he does have more experience than Naegi. He is also usually solving his cases alone with minimal input from whoever his sidekick is that day. The only reason Naegi solves his mysteries, is because he not only has a room of people helping out, but an actual talented detective too. At the end of the day Phoenix Wright would take it
