  • When K.O. accepts that T.K.O. is him and he is T.K.O., this acts as a reference to the Persona franchise such as Persona 4 when a person accepts their shadow.
  • When T.K.O wrestled Pird, he did the infamous "You Can't See Me" taunt by WWE wrestler John Cena to Rad and Enid.
  • When Rad first turns turbo, he can be quoted saying "Get ready, little man". This can relate to Sugilite's, from Steven Universe, words after appearing and showing Steven what she can do, which were "You like that, little man?"
