I'll have to side with Riku on this one. These two characters belong to Scott Cawthon and Toby Fox (respectively), and they... haven't exactly been on Nintendo consoles.

The reason Solid Snake, Sonic, Mega Man, Pac-Man, Ryu, Cloud and Bayonetta got into the game is because they've actually been on Nintendo Consoles (for those who don't know, in Cloud's case, he was in Final Fantasy Tactics for the DS)
