Solarisen (Japanese: フィニクス / Phoenix) is a dual-type Fire/Dragon Pokémon, and is one of the original Fakemon created for Pokémon Altair, Sirius and Vega.
It evolves from Guldawn starting at level 45. It is the final form of Mornwing.
Solarisen is a Pokémon with very high Special Attack and Speed stats as a Special Sweeper. It can easily be a Special Attacking beast with Nasty Plot, but training one will prove slightly difficult due to its surprisingly barren movepool. (...which is rare for a Pokémon in Vega without having to use TMs.) Its base form, Mornwing, can be caught at Fire Island at levels 34-36, although you can run into Guldawn very rarely at Fire Island.
Solarisen's Fire/Dragon typing along with the Levitate ability gives it good defensive utility, removing its Ground weakness and leaving it susceptible only to super-effective Dragon-Type and Rock-Type attacks. In addition, Fire/Dragon is a very strong offensive type that only Heatran can possibly resist, due to it having resistance to Dragon and immunity to Fire thanks to Flash Fire.
