Heirlooms is a Super Smash Bros. Fanfiction written by Reevee21, about how two young boys find twelve peculiar toys that their great-great-uncle had brought in from the Amazon, and how those toys come to life. It is currently in the Smash 64 Arc, with the only Smashers living at this point being the Original Twelve and Mewtwo, because Duh! It is an Origin Story of sorts for Master Hand, Crazy Hand, and about a few other deities of some odd Alternate Universe where Nintendo doesn't exist.
This Story has examples of:
- Author Avatar - One for every asset of Nintendo that had contributed to the Smash Bros. Canon.
- Everything's Better with Plushies - All the Pokemon shown thus far that Aren't Pikachu and Jigglypuff were handcrafted by Freya and Caitlyn, even Mewtwo!
- Living Toys - A rare fanfic where this actually applies.
- Original Characters - Based on the Hands, as well as the companies that lent a hand in producing Smash Bros. over the years.
