Scalasc

Scalasc, the Angelfish Pokémon, is a Water-type Pokémon that evolves from Luvdisc when exposed to a Love Stone. It evolves into Alomomola at level 29.

Scalasc is based on the freshwater angelfish (Pterophyllum Scalare), from which it also derives its name (which ends in c like Luvdisc's, and is a palindrome like Alomomola's).

Scalasc was proposed by Mason Green as a way of tying together Luvdisc and Alomomola as part of a single evolutionary family (as they were originally theorized to be by fans).

The fact that it ties together two previously unrelated Pokémon into a single family makes it analogous to Tyrogue (which tied together Hitmonlee and Hitmonchan).
