Umbreon
Improvements
It depend on what you think, I personally think that Espeon and Umbreon is the rarest evolution, because it takes you forever to get them, you need to raise their happiness to 220 ( if you don't know what it means, it's the happiness point) at day ( Espeon) or night (Umbreon ) then level up, but things change in Pokemon Heartgold/Soulsilver, Glaceon and Leafeon are the rarest in those games, because you can't get them at all! the only way you can get them is trading it into Diamond/Pearl/Platinum, evolve it, then trade back. You have to find a water/fire/thunder stone to evolve to Vaporeon, Flareon and Jolteon, and I can't find those stones!
So it really depends.
The trainer Skier Lexi on Route 217 has Eevee's evolution in Pokemon Platinum. The trainers on Route 212 and 214 also have Eevee.

Eevee's Dark-type evolution form is named Umbreon. In the primary core games, Eevee evolves into Umbreon when it has full Happiness during the night.
The only fire Pokemon in the Sinnoh region are the Chimchar-Monferno-Infernape evolution chain or the Ponyta-Rapidash evolution chain. However, once you beat the Pokemon League you can get an Eevee and evolve it to Flareon.
there is no rarest Pokemon you have to train and train and including shinies there is no real rarest Pokemon at all.
eevee
Ditto
As it stands now there isn't a poison type evolution of eevee but you never know their may be one in the new Pokemon games; Pokemon Black and White, but I don't know. The least we can do is hope their's a new evolution of eevee, right?

Yes you can. Since both Glaceon and Ditto are breedable Pokemon. You can also breed any Eevee evolution as well as Eevee with Ditto to get an Eevee.

Eevee's evolution are not legendary.
Eevee evolves into Vaporeon with the water stone, and that's it. Vaporeon is Eevee's last evolution, only 1 of 7 eevee evolutions.
None of the Pokemon from any other generations have any new forms in Black and White. No. Eevee did not get a new evolution.
135 is Jolteon, an evolution of Eevee. You can't find Jolteon in the wild, you need to evolve your Eevee by using a Thunderstone.
Eevee evolves using Evolution Stones, Fire Stone to Flareon, Water Stone to Vaporeon and Thunder Stone to Jolteon.
