- Toxeon is my custom-made Poison Type Eeveelution. You may be wondering, 'Fennekin, how do you evolve Eevee into Toxeon?' Well, you have to catch a Oddish, Gloom, or Vileplume, or any Poison Type Pokemon of your choice. But I suggest a member of the Oddish evolution line. But it won't work if you catch a Bellossom, since when you evolve Gloom into Bellossom with a Sun Stone, it loses it's Poison Typing. and becomes a plain Grass Type. Once you catch the Poison Type Pokemon, your Eevee will start evolving into Toxeon. So, that's how you evolve your Eevee into Toxeon.
