Pixie:Disappear. *turns Captain Clay into a Lost Disc*
Ditto with Captain Scale Jell:
You're going to have to destroy that boy with your bare hands!
Joker ensnares the heroes in illusions so he call kill them easily. Tiger sees Moo, Golem is led to believe he's drowning, Suezo is distracted by female monsters, and Genki and Mocchi are chained up...and Holly has daggers falling from the sky at her.
Gali proves to be Not So Stoic when he whips up a hurricane of sand to kill the Searchers, all because Genki cracked his mask.
Undine accidentally burning herself to death.
The gang finding remains of the Astros' space ship turned prison camp, including shattered lost discs, scrap metal that looks suspiciously like Astros, and broken prison chains.
The truth of the Pendant civilization, with the revelation that Monsters were created in test tubes to be warriors. Colt's toucan, Joy, underscores this:
Joy: Born in test tube! Squawk!
Moo does a lot of nasty things, and what makes it worse is that he can't be stopped until the finale.
His shocking of Pixie in episode 47. In the uncut version he visibly chops her wings off, and shocks Genki as well.
In a case of Bowdlerization making things more intense, Moo's beam attacks against the Dragon army. They're clearly hit, and in the uncut version they spiral to the ground like airplanes. By removing that, the dub implies they were vaporized on contact.
This face◊ Moo pulls in the uncut Episode 48. The animation for it is even worse, with his eye bulging and dilating.
