Wouldnt mind a Red Volcano 2.0, it'd give a fair reason as to why T.O. Morrow is still alive other then for Ivo to taunt.

But yeah you can pretty much tell by the shoulder, drew Manta once, the shiny bit on the shoulder piece sort of fits to the seam, with RV it's a bit different.since its the magma-circuitry type thing, his shoulder doesnt follow i perfectly and is a bit more rounded.

Alternately i assumed that the red light is from Manta's helmet laser blasts.
