What would happen if any of the Z Fighters I would have fought against Thanos? Are the characters of Dragon Ball much superior to those of Marvel? This is a question whose answer is subjective, although it generates intense debates.
However, nothing prohibits us from seeing how any of these characters would look in settings outside of their universe.
This is how this version of Android 16 appears, which in this Fan Art transforms into a non-Avenger and appears on the battlefield of the fight against Thanos, in Avengers: Endgame.
Number 16 would have been a great help to Iron Man, Captain America, Thor and the rest. Although they still won and successfully reversed the blip, perhaps with the Red Patrol android Tony Stark would not have died.
The illustration featured in a 3D Games review shows this brutal Android 16 with Thor-like power with thunder coming from his eyes and hands. In this universe there should not be a Goku, so surely the character would have fought for the side of good.
Android 16 is one of the kindest villains in Dragon Ball history. Literally all he wanted to do was accomplish his goal of killing Goku. After that he just wanted to preserve the animal species and the flora of the Earth.
