Skeledeath Mask

is a mask item worn by Maxx that was stolen from a defeated skeleton in the rocky dirt layer of the underground while adventuring with Cyril (who was regretting it). It becomes stuck on his head and he keeps it on (not admitting that it was stuck) until comic #81 where he accidentally breaks it. While wearing and shortly after losing it, Maxx makes a couple of He-Man jokes/references (calling Cyril He-Guide).

And you too can be Skeledeath by wearing a Skull dropped by Skeletons in the actual game.

It first appeared in comic #76.
