Other additional info I forgot to mention in the OP.
His weight, and age,
He doesn't exactly remember his age, but he's hella old. He may not LOOK like it, but he has quite a long past, and old friends, and foes. He's one of the oldist things out there, easily 50,000+
His weight varys, depending on how well fed he is, but, due to his size (About 7'7" tall standing on all fours, and 8'11" from tip of tail to tip of snout (I think I dun goofed with the sizeing)) and the metal content in his body, he easily weighs 8 times more then any standard darastrix his size. ((Again, I've been trying to pin down an aprox weight.))
