Obelisk rises from the ground as it has done every year, marked
with hieroglyphics on the top. Presumably the good guys have got
to it first and used its powers for good all previous years, but
now Skeletor wants to gain its secrets. The fight that ensues leads
to some really corny dialogue (I mean really corny) and it ends
up that a power struggle happens between He-Man and Skeletor, who
both gain "ultimate power." As they utter magic words
at the monument, creatures for good or evil appear from the Obelisk.
Finally, they both say the words at the exact same time and the
creatures and the Obelisk explode, but a voice from the ground says,
"The Obelisk will return..."
