Yes Umbreon learns hypnosis I don't know when though. Get it to level 60 and go to the move toutor.
Kecleon and Mightyena learn it while leveling up. Almost every other Pokemon can be taught the TM thief.
Any Pokemon raised good enough can defeat an Umbreon (as with any other Pokemon), but Pokemon that have a type advantage against Dark types (those types being Fighting and Bug) have, well, a type advantage.
you have to get a pokemon such as Golbat or some other flying pokemon that can learn it. i know this is true because i have gone against golbats that know air slash and i have one too
All Pokemon with a water-type can learn it. There are some other Pokemon that can learn it, but mostly water-Pokemon.

It is known as being Blaziken's signature move, but in Generation 4 (Pokemon Diamond/Pearl/Platinum to Pokemon Heartgold/Soulsilver), Hitmonlee could learn it naturally through level up and Chimchar & Riolu could learn it through breeding.
You can never trade Pokemon from Black to Platinum, because Generation V Pokemon do not appear in Platinum or any other game before Black and White. However, you an transfer Pokemon from Platinum to Black after you beat the game.
No, you don't. It has a full storyline in Platinum.

Umbreon from Pokemon is a psychic-type monster that uses psychic-type powers. It also uses melee attacks such as tackle and other moves. It also uses scratch, a melee attack.
It is possible to trade Pokemon platinum to diamond and pearl, but you cannot trade to any other game.
Diamond, pearl, and other platinum versions
They don't
you see all the Pokemon in platinum and trade from your other games like emerald, blue, fire red etc and that is how you find all Pokemon in platinum.
