i think im gonna go wiiiiiith 1...?
1. he stole his current name(Decibel)
2. he accidentally joins a street gang(it's later disbanded however)
3. he has multiple pokemon named after characters in fairy tales
EDIT: nope! he actually really did steal his current name of course the person he stole it from died but he still stole it
it was actually 3 i noticed i surprisingly never named someone after a fairy tale character in his nuz run
