The move does, but it isnt a TM anymore...:(
If you want to teach it to a Pokemon that doesn't learn by level up you need to breed.
The move isn't a TM anymore in Pokemon Black and White and can only be learned by LVing up or by Breeding....
You can get the move dark pulse in black 2 and white 2 with out breeding or levleing up by going to lentimas town and going into the move tutors house (wich is the t
op left house) and speaking with the old man, you will need x10 blue shards. The move dark pulse is the last move on his list. Hoped this helped :-)
