Discord's sacrifice

Here's Aku (from Samurai Jack) killing Discord (from My Little Pony: My Friendship is Magic) using his tentacles while trying to save Fluttershy, Marceline (from Adventure Time), and Oswald the Lucky Rabbit. Fluttershy is crying for losing him while Marceline and Oswald are shocked at Aku killing him. It's one of my most saddest, darkest, and most mature drawings.

Aku is owned by Genndy Tartakovsky.
Fluttershy and Discord are owned by Hasbro.
Marceline is owned by Pendleton Ward.
Oswald the Lucky Rabbit is owned by Disney.
