|This article is about a/an monster in Power Rangers S.P.D.|
An unknown alien appears on Gamma Orion when the SPD Power Rangers receive a distress call. This alien goes head to head against the Red Ranger while Krybots handle the rest of the Rangers. After putting up quite a resistance, he is put under arrest.
- This alien is unnamed, it is given the name "Roswell" on this article as it resembles the fake Roswell alien.
- Another individual of "Roswell"'s species appears in Endings. It is one of the SPD cadets in the scene where Kat and Boom address the cadets about the Troobian invasion.
