Ucyuseruzo of the Influenza (流感のウチュセルゾー,Ryūkan no Uchuseruzō?): Ucyuseruzo is a Bugntes Alien (バグンテス星人,Baguntesu Seijin?), able to sneeze out a virus that infects kids and makes them into smart students. However, that's just a side effect of the kids being turned into Bibi soldiers. After an antidote is devised, Ucyuseruzo is defeated by the Gosei Buster, and then destroyed by Seaick Gosei Great.
Ucyuseruzo's species name, Bugntes (バグンテス) contains kana from the English word "stinkbug"
