A couple of slight quibbles:
1: The maneuver that Battlecat takes is called "Sudden Leap", not "Tiger Leap". Also, it has a prerequisite of one Tiger Claw maneuver, so you'll need another Martial Study in there somewhere.

2: This appears to rely on the interpretation that, for shared spells (or spell-like abilities), you can choose different parameters for the recipients (in this case, a Medium form for He-Man, and a Small form for Orko, on Humanoid Shape). Not a big deal, since I think that's the most common interpretation, and I agree with it, but worth mentioning, I think.

3: It looks like Humanoid Shape is the only reason that Dragonfire Adept is in this build. OK, it's a good invocation, and you do get a couple of other utility options from it (basically, Burning Hands and Detect Magic at will), but it feels like kind of a waste to have a class whose primary feature adds basically no power nor flavor. Now, if you found a way to include Fly-By Breath, that would be something.
