ALT 13 is a fusion of one and three! They’re actually one of the more energetic fusions despite one and threes complicated feelings towards each other. Why? Well they’re both scared yet yearning for one another which makes for an exhilarating experience. Plus both haven’t had physical touch in years so they’re a lilllll excited. (Extra for alt readers hehe): Three when fused doesn’t feel as much chronic pain at being yknow… valueless and she gets to have her other eye again just like old times.. whilst one gets the pleasure of having arms. 13 enjoys helping others out and puts 100% into everything even if the task is mundane. They’re also pretty competitive with games
