It would make sense that he would have;
A) some sort of futuristic weapon / multi-tool (other than the ubiquitous 'bigass gun'), perhaps designed by some mutant super-genius like Forge. A rod like the one the short-time Avenger Magdalene used, that could function both as a melee weapon, parrying device and ranged blaster (and could be used as a welder, power-supply or even a light source), would be ideal.
B) training and hand-to-hand skills for when his power isn't charged up and available (since it is dependent on someone blasting him to charge it up), so that he's capable and effective even without his mutant power.
I'd want to avoid giving him more (or better) powers though. IMO, that's just a lazy out, and if 'more/better powers!' had any correlation to how much traction a character had, Gabriel Summers and Mikhail Rasputin would be the most successful and popular members of their respective families.
The power he has is great, narratively, since it's strong, but has some restrictions built in, making it like Cyclops. (Yet another thing they share!)
