[Captain Nash]

Based on the recent comic events we can expect to see:

Red Skull-Onslaught

Horseman Sentry (nevermind we need a Grim Reaper in ML anyways let's do a Horseman of a figure we've already got) same goes true for Horseman Daken

Old Nick Fury

What I would love to see but would never happen:

Astral Plane Shadow King
Attuma (okay, this one could potentially happen. Probably not but I wouldn't say NEVER)
Titania
