Witty and quipping, yes. Would-be hero is a stretch--by Wrathion's consideration, he's no hero at all. He'd suppose he were close enough, considering he doesn't want the world to end, if he were asked.

"Oh, never fear that," Wrathion responds, voice silky. "I've laid low bigger foes than you!"

As Zenos springs for him, Wrathion leaps, too. He hasn't got wings in this form, but proportional strength makes him able to do a convenient twist in the air. This allows him to plant a foot in the bigger man's face with good force behind it. Then to add insult to injury, he uses his momentum to springboard off, grinding his right foot and kicking back with his left to dig his heel into the big man's broad back, flipping into a crouch. He skids a bit along the ground, but reaches out with the hooked end of the gaff to attempt to trip Zenos, now. He doesn't expect to catch the Garlean's ankle, but if he does, he'll yank hard, hoping to bring him down.
