He-Man and the Masters of the Universe(2002)

A sword will choose a master, a boy will become a man, and a hero will be born.

Years ago, two leaders battled for the fantastical land of Eternia, one became the good King Randor, the other grew into the evil monster Skeletor who plans to rise once again and take Eternia. To protect the kingdom, the mystical powers of Castle Greyskull chose a hero - Randor's lazy, impulsive teenage son Adam.
