First, he needs to learn how to summon his weapon, because most of the ideas I have are for modes or upgrades to it.

I'm using the weapons from the online Hero's Duty game (though a couple of them showed up in the movie) as a base for his powers.

His weapon will be just a basic gun, nothing special about it.

There's 4 different guns/modes in the online game:

-Weak pistol, has unlimited ammo no matter what

-Machine gun, can constantly fire

-Sniper rifle, has a scope to see things closer, but can only shoot like one bullet at a time

-Grenade launcher - Is very slow at firing, but can shoot grenades that have a blast radius

That should give him enough to work with for a while. There's not really much else I can give him, aside from medals and Cy-Bugs. Maybe one of the cruiser hoverboards, that could be fun.

There's also the combat knives and bombs that Calhoun also had.

Wreck-It Ralph: Hero's Duty - Here's the link to the online game, though I don't think it works in Chrome because it's a Unity game.
