A Pikachen is a swan-like creature that resides in Asgard.
For those not familiar with them, the Pikachen's appearance may be confused with what is possibly its mundane equivalent, the swan. This similarity is a possible indicator that the Pikachen may or may not be a type of bird.
The Pikachen is first (and only) mentioned in the second season of the show when Frederick was flirting with a girl at the Bent Elbow and gives her a little Pikachen made out of a napkin and she, in her ignorance, confuses it with a swan.
- The name Pikachen may be a reference to the Japanese anime character, Pikachu.
