I'm having several of my superpowered characters do a simulated scrimmage, with paintballs. These characters have various powers: telekinesis, electric manipulation, water manipulation, energy manipulation (force fields, energy balls, etc.) , light manipulation (which includes being able to manifest lasers and illusions), air manipulation (which includes sonic manipulation), and heat manipulation.
This last one is the most troublesome. According to the rules, there are several targets on the person's body which must be hit by a paintball for them to be out. It's not allowed for a person to guard only their targets, but they can guard their body. It's obviously difficult to hit any of these characters (duh), but the thermokinetic gives me some problems.
The thermokinetic just radiates an aura of heat (which he can obviously control) which is warm enough to make bullets melt before hitting him, let alone a paintball. How would it be possible to hit the thermokinetic with a paintball? You can use the abilities of other people (listed above), or you can just get creative and use some sort of strategy/superpower combo.
Note: Assume he doesn't have a weakness, and there isn't an excessive amount of water available (though you'd probably need somewhere around a lakeful).
