1 Alphys' way of "feeding" the Amalgamates in Undertale is actually very largely to nakedly pleasure them and serve as their nightly vore victim when no one's looking, effectively living out her wildest hentai fantasies
2 Raz and Dr. Loboto are both unbearably sexually attracted to brains in Psychonauts; in fact, the former and Lili kept their Smelling Salts handy largely so that they could take turns getting down and schwifty with each other's violently-sneezed-out ones
3 The original Tingle from Majora's Mask was actually the horrifically birth-defected, immensely low-functioningly autistic result of Ocarina Of Time's Great Fairy having several unprotected affairs with Young Link
He is not autistic.
4 Sans and Papyrus from Undertale actually represent the left and right hemispheres of Gaster's brain
5 Lammy's impossibly sexy character design in Um Jammer Lammy is actually a quite accurate personification of what the average New Zealander sees when looking at real-life sheep
6 Dr. Eggman from the Sonic series was actually Wario's abusive father in the Mario series
7 "Yidder", as heard in the now-infamous Tomodachi Life song Operation Robodachi Fist, is actually an in-game racist term for Miis whose favorite foods include watermelon and chicken
8 Waluigi is a genie
9 Bentley from Sly Cooper is actually the distant European alternate-universe secret-agent cousin of Filburt from Rocko's Modern Life

15 Peach is actually Bowser Jr's mother
16 Inklings are idiots
17 Link and Zelda are Toon Link's parents
18 Kirby is Meta Knight's son
19 Ninten is the father of Ness
He was set in the early 80's, and Earthbound was set in 199X, whenever that is. Ninten also has psychic abilities like Ness, has black hair, and Ness's dad says on the phone, "I feel like a hero", which he refers to his own adventure, but is glad Ness will keep the legacy of fighting Gigyas.
20 Dr. Mario is the third Mario brother
21 Super Smash Bros is an Autistic boy's imagination while playing with toys
The intro for the original N64 game sees Nintendo toys being played with. When Master Hand is defeated, the character gets put down on a desk, and the kid playing with it closes his door.

46 Luigi is physically more powerful than Samus Aran
