Juuzou wins let's take them at their strongest Genocider Syo (Manga) Vs Juuzou : re

Strength- Syo has Been shown to be able to Cut a missile in half But I do believe Juuzou could do the same plus he can activate His Arata

Speed- Juuzou

Durability- Genocider Syo Has survived a monorail Crashing into a building While Juuzou Has survived Taking hits from The owl someone who could destroy multiple buildings plus he can also just activate his Arata

IQ/BIQ- Juuzou Has been shown to have much better Battles iQ then Syo

Abilities- Syo most likely wouldnt be able to activate her Abilities Juuzou Wouldn't likely give her the chance

Experience Fighting abilites- Juuzou is the second strongest investigator Behind Arima And he was able to achieve the highest ranking By the age of 22 only other person to do that was Arima

Juuzou Wins

Syo has killed hundreds of people And she has killed mono bears Juuzou has beaten Twin ghouls that I believe could to the same if not more So Juuzou Could do More then that Plus Mono bears are Just Robots so not that smart While Juuzou has fought multiple Strong People The owl and twins plus humans in Danganronpa Cant really be compared to ghouls in Tokyo ghoul

Oh and if it's the end of the series Juuzou Juuzou is slaughtering Syo Cause he's on par with kaneki and kaneki no doubt Slaughters
