Tame, yes. Potentially scary looking? Definitely. He was a great big powerful stealthy monster on wings, with lots of firepower in case his array of sharp pointy objects didn't do the job of completely ruining most targets. No doubt he could easily be confused for something harmful, even in his best of moods.

Toothless could tell that Duo wanted him to take notice of the other human, so he gave in with a rumble. He left the older pilot's side and moved to the younger. He stopped just out of arm's reach and sat, crouching in on himself submissively, paw lifted from the ground and ears only slightly erect. There was a low purr coming from him as he looked up at Heero with great big eyes and dilated pupils.

After determining whether or not the other would attack him, he moved in close enough to sniff at him, starting from Heero's chest and working his way up to the head.

Yup. Seemed to check out just fine. He sat back again, ears and wings perked.

"Auuurghrraw," he greeted before promptly ignoring him and turning back to Duo. There. Made friends. NOW will you cheer up?
