since you just got a robot, I would like to recommend 16, from the game Dragon Ball FighterZ, he is peaceful, 100% mechanical, and he is stronger that a Super Saiyan, just for you to have an idea of his utility, 16 can survive in space, he never gets tired, he never runs out of energy, he can be connected to Jarvis to reverse engineer his perpetual motion motor, just so you know, the power source the androids use is better that the Arc Reactor Tony Stark made, and it is cheaper as well, not to mention that he is strong enough to destroy planets, 9000 power level on dbz is enough to destroy a planet, 16 power level is above 1 million.
