There's a high-rated arc featuring him in a prominent role, so he's either in it or someone has a knack for re-creating lore characters.
I don't think he's in it. I had to remake him for one arc I used him in. Fortunately he's not using any special costume pieces.

Thought as much. I'll just recreate him 
Is he in the MA at all? Had a look for him but no joy
