There was the episode where Skeletor was doctoring video transmissions and planting evidence to make Stratos' bird-people go to war with Buzz's bee people. He-Man found out and charged off to warn everyone in person that they were being duped.
Then it turned out that Skeletor was trying to start the war so Buzz's hive would be undefended, so he could get his hands on magic Royal Jelly that would make him super-powerful!
He-Man continued running to stop the battle.
Skeletor got his hands on the powerup, and war started between the two sides.
He-Man finally showed up. He fought Skeletor, who was now super powerful and it looked bad for the heroes, when suddenly... out of the blue Skeletor and his minions lose all their power and become super weak.
He-Man: "Ha ha ha, I knew all along what you were up to. And what I knew and you didn't was that the magic royal jelly only gives a temporary power boost, but then leaves you weak! Also, you guys fighting should stop."
That was the resolution. An out of nowhere never-set-up twist that Skeletor was a retard and the power-up he was after had actually been useless the whole time. He-Man had been shown frantically running like there was a serious problem to solve, but it turned out there was never a real cause for concern.
2002 He-Man was a garbage cartoon, an utter waste of the time and talent of everyone working on it.
