I remember the ones Vultureman got super powers from a potion! And one where someone freed Excaliber to battle the Sword of Omens

I'd also have to cite "Garden of Delights" as one of the show's most memorable eps, and with it "Crystal Canyon" with the Keystone. One can argue if these are truly among the shows best episodes but for an 80s cartoon they both depict the negative effects of drug addiction vividly and creepily. "Garden" after all has Tygra going on an acid trip after eating the Silky Fruit and then crashing rather badly and being totally strung out from it. "Crystal Canyon" meanwhile has the Keystone that drives Tygra to paranoia & eats away at him so much that he's reduced to a 90 lbs weakling; sure he gets the muscle back at the end of the episode thanks to the Sword of Omens being a 5 second rehab detox machine but still seeing the physical damage of addiction rendered in such a creepy fashion is very impressive considering the time period the show was made in.

The Tygra ageing episode or the Tower Of Traps, always scared me.

Yeah, the 5th episode of Lion-O's anointment trials. They really do a good job of making you think Mumm-Ra is dead. I think they should've carried that over into a few episodes to really sell it, then have Mumm-Ra brought back through some dark magic or artifact.

Mine also involves Trygra; "Garden of delights", which is an episode that acts as a drug metaphor. It's not my favorite episode, but I thought it was a really brave and interesting thing for a children's cartoon to do, and I've never forgotten it.
