Trainer on route 212
i dont kown i dont kown
On Route 212, a trainer has it. That is, if you just want to see it to complete the dex. There is no where to catch it on platinum, though. You'll have to make an eevee happy at night to make it evolve into an umbreon.
If you go onto that muddy trail past pastoria city, you will see a collector trainer, battle him and he has a Umbreon and a Espeon
You have to train an Eevee by happiness at night
well, you can see a trainer with it in the battle tower/battle foniter
a trainer in victory road has one
You can't 'see' an umbreon in Platinum. You have to level an eevee at night, or make it friendly. That counts as catching it and seeing it.
1.) If you mean just see for the national Dex there will be a trainer in Route 212 2.) If you want to catch one get an EEVEE from Bebe (In Hearthome City) and get his\her happiness maxed during the night.
The trainer in Victory Road
sorry you cant, you have to evolve your evee during the night it will be either a umbreon or a espeon. so its the matter of luck on getting the one you want.
You can't catch it but you can see it. A trainer south of victory road has it.
Go to route 212(the rainy route) and there will be a trainer with a umbreon there. GOOD LUCK!
