After watching Pixel Dan's review of Demo-Man, I couldn't stop thinking about the extra skull that comes with this figure. Who was that? It's easy to say since the horned helmet on the skull looks close to the helmet Vikor wears this could be a closed case. But doing some research, timeline-wise, it could make sense...
In Demo-Man's bio it states: Hordak intended to use this ruse as a means to escape once the portal was opened, but the new merged being Skeletor was quickly defeated by Oo-Lar...
Now, Oo-lar is suggessted to be the protector of the power swords after Vikor and Wun-Dar:
- KING GRAYSKULL, "Heroic Ancestor of He-Man": 500 years ago.
- VIKOR, "He-Man of the North": 1st "He-Men", 500 years ago.
- WUN-DAR, "Savage He-Man": 100 years ago.
- OO-LARR, "Jungle He-Man": Great Unrest.
- PRINCE ADAM, "He-man": Present. Adam is the first to tap into the Power of Grayskull to transform and then call himself He-Man.

So chronologically, it could be possible the skull head belongs to the deceased Vikor...cha think?
