Choose one hobby or skill within reason (Boxing, singing, pro-gaming, computer programming, etc.). Your talent with this skill is now as if you had trained in it for an entire lifetime while being naturally gifted, and you're able to improve that talent further. Becoming an Ultimate Computer Programmer could allow you to make artificial intelligence, while becoming an Ultimate Boxer could make you a Brute/Mover/Striker/Thinker grab bag cape through this power affecting both your body and mind as appropriate.
