[@hatakekuro]Depends on what you mean by being of use. If you mean in a fight, then sorta-kinda-don't-be-surprised-if-he-gets-wrecked. He's never really been in a real fight, so his skills are sub-par, and due to the fact that most of his abilities have to include touching, it'll be a while before he can get really creative without having to take a hit.

In support and info-gathering, he's got some tricks that cna certainly help. Not quite sure really, since it's a broad ability with a lot of neat applications.
