The man to whom Arty had been speaking suddenly disappeared in a puff of space-time, and his eyebrows rose in surprise. That was the second fellow in less than five minutes who preferred to flee than face him as a true adversary. He glanced around at the others to see if they'd noticed, and his eye caught sight of a small lobbed projectile heading his way. Looks like someone else was finally taking an interest.

Arty's left hand shot up and snatched the grenade out of the air, instantly permeating it with a small cohesion field that locked every piece of it together, preventing the device from detonating. "Tsk, tsk, my friend. You should at least introduce yourself before giving a guy a present. Especially one as lovely as this." He held the grenade up to inspect it, but only for appearances sake. He kept his attention on the battlefield around him, and most notably on the newest arrivals. He had at least and idea of what the others could do, but these new guys were wild cards. And for some reason, he couldn't sense the kid's electrical aura. Actually, now that he thought about it, he couldn't sense the skeleton's either. Huh. Must have something to do with being undead. As he stood and observed, his attention seemingly focused on the grenade he held, small sparks began to arc between the fingers of his otherwise unoccupied right hand as the energy he was focusing there continued to build.
