Where did the name "Space Umpire" came from? Addendum: I have found out the information is listed on the character site. Malalaika (talk) 23:51, August 11, 2019 (UTC) (Malalaika#3141)
It comes from the official website description of Air Batter! Specifically in this part: "後方でUFOに乗っているのは、スペースアンパイア。" Cure Alumi (talk) 04:16, August 12, 2019 (UTC)
