Just my two cents: If he wants to exploit powers to me that sounds like a villain. Now a super hero would take advantage of powers. How would time travel give you powers? As it shows on Legends it can be bumpy, disorienting, and possibly detrimental to your health, but none of that would lead to powers. Unless you go through something like at the end of season 2 end up in a time where time is barfing everything into one time, that may lead to powers if your character was destined to get powers eventually.
