This is my entry for Eevee evoltuions challenge!
It's Metalion, the steel type! I know it's black, white and grey, but it is it's natural color, so he would look cooler this way ^_^
To evolve Eevee to Metalion equip Metal Coat on it and trade it. Then it will evolve. It has high defense and the horn on it's headgear enables it to use Horn Attack, Horn Drill and special attacks such as Thunderbolt, Ice Beam and Hyper Beam.
That's it! ^_^ Hope you like it!
