Lets begin with the most obvious.Mole Man Is known for rolling with a crew of monsters and alien like ,subterranean creatures.While there are a few that are unique to Mole Man ,who says you can't throw a couple of these Rathtars into the background for an added effect.I think they're a match made in ...hell?
Silver Surfer Is an alien life-form himself,so he Is certainly no stranger to encountering Rathar-like creatures while traversing outer space.
Rathtar's could easily be one of Dormammu's many demon lords.Dr.Strange would have his hands full with these two.
I could definitely see an enraged Hulk going toe to tentacle with a couple of ravaging Rathtar!
humans will be enslaved and closely guarded by Rathtar ,when not being used as food for them to snack on ;)
Rathtar's are big figures.They will take up a significant amount of space on your 3 3/4 figure display but you can always pose figures in between and around the tentacles to make things fit.Notice,though,how I had to place Sabretooth,Mystique and Juggernaut towards the back.
