Zarrko in Marvel Universe: The End#2

[loki]

Zarrko is visible in the sphere containing trapped time travellers in Marvel Universe: The End#2. He's in a costume he only wore (afaik) in Thor II#43 and 50, so it's easy not to recognize him (I didn't either - it was fellow Appendixer/Handbooker Michael Hoskins who IDed him), but it's definitely him, and it's not on his MCP appearance list. Comparison image below - on the left Zarrko in Thor II#43, on the right the character in Marvel Universe: The End#2.

Yeah, if you squint, you can see the resemblance.
