MEANWHILE in 2018, Newgrounds has changed up their flash format and presentation somewhat. The fact this now plays like a movie, and not an interactive swf, means the "choose your winner" screen always auto selects Kakashi. I wanted Gohan to win, Gohan is a beast among beasts, have you not watched his Dragonball Super return to power arc, where Gohan overcomes his weakness in ultimate form?
While I've read the other reviews and understand you didn't select these characters, a depowered and "out of shape" Gohan still is sturdy enough to break a fully grown adult male bodybuilder's arm, just from being punched in the jaw (orange star highschool arc).
On the other hand, I'm not going to argue that Kakashi is a joke, because he isn't, Kakashi is a prodigy in his own right. It isn't easy to be able for a non Uchicha to activate the sharingan, the strain it takes on the body has been noted several times, especially in Kakashi's case, using mangeyenko sharingan takes ten times the charka and stamina that any other jonin normally would have; and he STILL pulls it off.
Overall I'm mildly satisfied with this flash, so I'm bumping up my 1 star score (broken choose your winner screen), up to a 2½. Fix the ending "choose your winner" to get a bigger raise.
