Since the very beginning, back in RBY, Pokémon have been able to evolve, giving them new moves, abilities, types (sometimes) and generous stat boosts (usually)! But what if we could cross these evolutionary lines? That's what you can do here!
By nicknaming a non-fully evolved Pokemon, you can cross evolve it, granting it the corresponding stat boosts and type changes, full access to the evolution's movepool, as well as replacing its abilities with that of its evolutions.
Complicated? Want an example? Ok!
Bisharp is a Stage 2 that can evolve into a Stage 3, so it can cross-evolve with a Stage 3 Pokémon such as Dragonite. Dragonite has +30 HP, +50 Attack, +30 Defense, +30 Special Attack, +30 Special Defense and +10 Speed compared to Dragonair. Its abilities are Inner Focus and Multiscale, and it gains a secondary Flying-type. The result of cross-evolving Bisharp into Dragonite is as follows:
Bisharp (cross-evolved into Dragonite)
New Abilities (completely replaces old ability pool): Inner Focus/Multiscale
New Stats: 95/175/130/90/100/80
New typing: Dark/Flying
Also gains access to Dragonite's entire movepool, in addition to its previous movepool.
To cross-evolve in the teambuilder, nickname the base Pokemon after the evolution. In the case of Ursaring-Dragonite, for example, give an Ursaring the nickname "Dragonite". If you want to see the stats of any cross-evolution, the /ce command is very helpful!

Q: How does Eviolite work? What about signature items, such as Light Ball?
A: Eviolite and signature items do not work on any cross-evolved Pokémon. Due to a visual bug stat increases are still applied on the client; they are not, however, factored into damage calculation.
Q: How do forme-change abilities such as Zen Mode work?
A: For all intents and purposes these abilities don't function on cross-evolved Pokémon, in the same vein as Pokémon-specific held items.
Q: Is weight affected? What if my cross-evolution's weight drops below 0?
A: If weight drops below 0 when cross-evolving, it is set to 0.1 kg.
Q: How do I view cross evolution data on Pokemon Showdown?
A: The /ce [base], [evolution] command will show you the complete stats of a given cross evolution, while the /showevo [evolved Pokemon] command will show you the stats, abilities, and typings provided by any given evolution.

Mechanics |
To cross-evolve in the teambuilder, nickname the base Pokemon after the evolution. In the case of Ursaring-Dragonite, for example, give an Ursaring the nickname "Dragonite". If you want to see the stats of any cross-evolution, the /ce command is very helpful!
- You can "cross-evolve" your Pokémon by naming them after the intended Pokémon.
- Stat, typing, and ability changes granted by any evolution are determined by their respective changes from their prevo. For example, Corphish has 43/80/65/50/35/35 stats and is pure Water while Crawdaunt has 63/120/85/90/55/55 with a Water/Dark typing. If you were to evolve something into Crawdaunt it would gain +20 HP, +40 Attack, +20 Defense, +40 Special Attack, +20 Special Defense, and +20 Speed as well as a secondary Dark-type.
- Evolution is limited so that only Pokémon that are able to evolve may do so, and they must follow evolutionary stages. Stage 1's encompass most of the LCs and may only evolve into Stage 2's, while Stage 2's are primarily NFE and may only evolve into Stage 3. Scyther is a Stage 1 Pokémon and can evolve into any Stage 2 but it cannot evolve into a Stage 3, so you couldn't evolve it into a Stage 3 like Gallade or Dragonite, but you use Stage 2's like Umbreon or Dragonair. This applies to Stage 2's as well.
- In case of confusion, here's an infographic to help visualize this:
Stage 2 Snorlax ✔
This is a legal evolution because Charmander is a Stage 1 and can evolve under normal circumstances.
Stage 2 Snorlax ✘
This is an illegal evolution because Charmeleon is a Stage 2 and cannot evolve into another Stage 2.
Stage 2 Snorlax ✘
This is an illegal evolution because Charizard cannot evolve under normal circumstances.
Stage 2 Dusclops
This is a legal evolution because Dusclops is a Stage 2 and can evolve under normal circumstances.
Stage 2 Snorlax
This is an illegal evolution because Snorlax cannot evolve under normal circumstances.
Stage 1 Munchlax
This is an illegal evolution because Munchlax is a Stage 1 and cannot evolve into a Stage 3 Pokemon. - Cross-evolve Pokémon gain the abilities of the evolution. This means they can no longer use their base abilities, i.e. if you were to cross-evolve Magneton with Hydreigon it would gain Levitate and lose access to Magnet Pull, Sturdy, and Analytic.
- Cross-evolved Pokémon have the movepool of both the base Pokémon and the evolution. In past generations there was a 2-move inheriting cap; in this gen it has been removed.
- Move and ability illegalities are ignored on cross-evolved Pokémon.
