Off of the top of my head, I know some of the Snake-Men appeared in both He-Man and She-Ra. Not sure who else.

• Fright Zone
• Grizzor
• Hordak
• Leech
• Mantasaur
• Mantenna
• Modulok
• Monstroid
• Multi-Bot
• Rattlor
• Rokkon
• Slime Pit
• Snout Spout
• Stonedar
• Tongue Lasher

@adam_prince-of-eternia thanks  that's a good list. I was mainly looking for characters, but I was surprised to see Mantisaur on the list. Hopefully we'll see Mantisaur in Origins soon. 

Also it looks like the list is mostly 85 and 86 releases. 

Spikor showed up once, in Loo-Kee Lends a Hand.

Beast-Man and Trapjaw got an appearance in Assault on the Hive.

I expect there were others, but that's just off the top of my head!

I took his question to mean what Masters of the Universe toys appeared in She-Ra: Princess of Power that did not appear first in He-Man and the Masters of the Universe, i.e. which toys debuted in the She-Ra series.

@adam_prince-of-eternia yeah. I'm mostly looking for heroic warriors that I could shift into the great rebellion. So far it looks like the Geolons and Snout Spout.

Webstor is one too.

@smitty-81 Oh apologies, misunderstood there!

I suppose the Meteorbs' appearance in Assault in the Hive might fit your criteria. Otherwise I can't think of any to add to Adam's list.
