Another popular Eeveelution design is the concept of dual-type Eeveelutions. Currently, Eevee does not have any of these. These are Eeveelutions which have two types, such as a Water/Fire type. It can be fun to design dual-type Eeveelutions if you wish to combine types or base an Eeveelution off of a certain thing, such as steam for a Water/Fire type.

Some unique features seen in existing Eeveelutions are the fins of a Vaporeon[5] X Research source and the ribbon-like feelers of a Sylveon. [6] X Research source

For example, you might name a Flying type Eeveelution “Aveon”, “Aereon”, or “Zephyreon”.

You can choose one of these ways or create your own way, such as, for example, trading Eevee to another player or holding a certain object. Use your imagination to create a unique way of evolving Eevee into your Eeveelution.

If you wish to, you can even create a Z-Move for your Eeveelution. Z-Moves are exclusive to the Pokémon Sun and Moon games and are very powerful moves in which the trainer and their Pokémon use their full power and can only be used once per battle. [10] X Research source Though the existing Eeveelutions other than Eevee don’t have their own Z-Moves, you can choose to create your own for your Eeveelution or make Z-Moves for the existing Eeveelutions.

Additionally, you could create a Gigantamax form for your Eeveelution. Gigantamax is a type of Dynamax, a concept introduced in Pokémon Sword and Shield, where a Pokémon greatly increases in size and appearance. [14] X Research source None of the existing Eeveelutions other than Eevee have a Gigantamax form, but this shouldn’t stop you from making one for your Eeveelution if you’d like to. You could also create Gigantamax forms for the existing Eeveelutions if you wish. This step is completely optional, however, and you do not have to create a Mega Evolution or Gigantamax form for your Eeveelution if you don’t want to.
