This is about the anime characters. For the monster itself, see Looker.
Lookers are female Suezo monsters that make several brief cameo appearances in the anime series.
Several Lookers are seen in Suezo's illusion in Episode 17, created by Joker. In the English Dub, they are edited out possibly due to the Playboy Bunny costumes they're wearing.
Suezo is often seen thinking about Lookers in daydreams, and in Episode 58 a Looker drives a taxi.
