Good on you, Gnawfist!

I=Incubus (?)
R= Razorback

R = Razorback
the font fits for it as well. Not that well known

It's safe to say R is something else; The sound you hear is a pig (look at the bottom right to see a tiny silhouette of one moving too)

H is definitely Hulk.. is R Russians/Red Dawn.. the picture makes sense and so does the horse sounds.. but don't know where that font comes from

Lycanthrope, You are right indeed (how did I not see that :/) The bixby tv-show tune!

I - Invisible man
O - Octopus

i thought H was hulk. am i wrong?
