Mole Man looks forward to riding his Hellcow into battle against the forces of the surface world!

Basically you put him in stealth and harass with energy explosion as much as you can. If they send any melee over to you, you simply mastermind the damage away and hit back with big moloid empowered swings. He's not the kind of guy you build an entire team around but him and some moloids are a nice addition to a monster theme.
