Callix

A member of Hordak's evil Horde, Callix was a new character created specifically for the 2002 version of He-man.

From what little is seen of him, he holds a position as one of Hordak's commanders and is shown to be fairly level headed when it comes to tactics, suggesting that Hordak postpone his attack on Castle Greyskull due to their forces being depleted after the war with the Snake Men.

Even though Hordak himself admits this is sound advice, he ultimately kills Callix merely out of petty spite and advances on.
