Mecha

The Mecha, Carlos' Alpha Version of his project, was the Ultimate Mech Titan who appeared at the very end of Ch 2. to consult Big Bro. He was called in by Mid Bro during the final battle, except he would unfortunately arrive all too late. He gets more of a role in Ch 3., where he would be the one to tell Big Bro about Dexter's kidnapping. Unfortunately he would get incapacitated by Locust F4's atomic breath before he could even do anything to showcase his abilities to us. This is why his abilities are still a mystery.
