(Sadness warning!) (Not canon to the real BFDI) Spinner's past: Before he joined BFDI, he lost his biological Christian family and parents, and they all went extinct and were killed secretly when he was just a newborn, but a couple found him in a city in Goiky and adopted him and treated him as if he was their own child in 2005 (His birth year). He loved talking a lot at school, but he got called annoying for it and was bullied by the other kids, so he talked less sadly due to this (He starts to talk way more during IDFB and BFB in the future). When it was July 14th, 2009, he spent time with his adoptive parents for the last time, and this was when he 3 years old. When he woke up on his birthday (July 15th, 2009), he was alone. He opened the last gifts his adoptive parents left for him and he enjoyed the gifts, but he wanted to spend his birthday with his adoptive parents and searched for them with his speed and Spider-Sense. The more he tried to search, he couldn't feel their presence anymore and silently mourned and cried for them sadly and went back to his adoptive parents' home and stayed there until December 31st, 2009. During August and the other months, his teachers and bullies felt bad for him and comforted him, but they didn't force him to go to school. But on that fateful day, on December 31st, 2009, the Announcer came to him and asked if he wanted to join BFDI. Spinner wanted friends and adventure, so he joined. And then things got better in the future.
Forgot to mention that he crawled to the city all on his own, so he was a really fast baby.
