Eatieon is a legendary eevee. Though Eevee cannot evolve into this form, it's still called an eeveelution.
The Eevee Pack just recently rescued 20 Christions yesterday!
Waspadon: He poked a giant hole in Eatieon's right wing!
Valentine: She saved a baby Christion, and threw Eatieon around!
Sylvii: She ripped off Eatieon's antler!
Shadii: He vanished in the moonlight and then appeared in his stomach and rescued 2 Christions!
