To me though, I don't think a manticore goes with Irvine for some reason, its a logical guess but I always thought his form would be somewhat "elegant" and smooth similar to how Locus is, and a hairy grumbled face beast with a scorpion tail doesn't go with that. Also he is blind with a demonic eye on his bow so I was thinking perhaps his apostle form would have a WHOLE bunch of those demonic eyes all over him. I mean it would be pretty horrific if when he transformed all these eyes open everywhere looking at you and then all this dangerous projectiles go flying towards you, and then when you get a good luck at him he is some elegant demon-like being.
