"Whoa...the fuck?! Get off of him!" Tommy snarled at the ugly whosit - it literally did look like a demon, or what he imagined a demon would look like. Claws, sharp teeth dripping with likely acid, hungry and vacant glowing eyes that could probably sear you down to your soul - yeah, that was a demon, and Loki seemed to be onto something about this lab being unstable. Since he went to Rosalind, Tommy - in a blink - was at the back of the beast trying to choke Robert out.
The Young Avenger acted quick enough to nearly be missed by the naked eye. He just hurled himself at the creature with wrecking ball force, grabbing and maintaining contact and it didn't even take much. Not for the vaporization, which was a sudden blast, smoke and particles exploding and something that smelled really bad. If he wasn't careful he'd set the lab on fire but he wasn't aiming to do that - just to get rid of the unwanted visitor.
