"True Colors", the S2 finale of Amphibia, aired 3 years ago.
You can think what you want of Amphibia, but it definitively hits my short list of the top best finales ever.
It's like watching an hour long movie seamlessly packed in a 24mn episode with twists and sequences you wouldn't expect - as I told myself when it ended: "What the fuck did I just watch?".
I often describe it as "Miyazaki meets Dragonball".
Also Disney Channel cancelled the premiere just before the broadcast because of the content, and that should tell you something.
