Potassium Power a name given thanks to the yellow paint left over from his former life as a construction bot.
Now a gladiator bot not as fast or graceful as the newer models but what he lacks in speed is made up for in brute stregth.

I did one of these a couple years ago and was lucky enough to fit d another hulk buster body
And ended up doing a lot of the same things in making it but gave it yellow paint because it makes it look bigger
And more patch worked
