Here is my updated version of Gravattack from Ben 10 Omniverse! At 100% scale, he stands roughly 4.7 inches tall

Files 2 and 6 are exploded views of moving parts to show you how they go together and what each part looks like, so you do not need to print these.

You may have to do some filing around the pegs on the shoulders and forearms to get them to fit correctly.

I have plans to make and upload Clockwork, Armodrillo, and Ultimate Kevin 11. If there are any other aliens you would like to see made, message me or leave a comment.
