Film, Television, and Anime references in Adventure Time

Since Adventure Time has tons of references to works in other mediums, I thought it'd be fun and interesting to make this thread.

Point out references to film, anime, television, etc, in Adventure Time.

I'll start off with this still http://storage.akamai.coub.com/get/bucket:12.21/p/coub/simple/cw_timeline_pic/de25f546d07/0a262e69f0f47a00e3da8/big_1409082326_1382453704_image.jpg

This is a very blatant reference to Guts, The Black Swordsman from Berserk, perhaps my favorite manga of all time.

They're both missing the same eye, both lost an arm and replaced it with a mechanical arm, both have giant similarly shaped swords and they both bandage up their hands/wrists. They also wear capes, but Finn wears a white cape (seemingly intentional), whereas Guts wears a black cape to conceal himself in the night.

There have been more references to Berserk; like Ricardio being a reference to the Crimson Behelit in Berserk.
