Like most New Pokemon Games - whether apart of the same Generation or the start of a new one - Pokemon: Let's Go, Eevee will introduce a number of Brand New Pokemon Attacks. This was confirmed with the reveal of Eevee knowing two brand new (and exclusive) moves!
The first New attack Eevee will be able to learn in Pokemon: Let's Go, Eevee is called Veevee Volley. It is a Normal Type Attack, but one that will do increased damage depending on the Friendship Level it has with its trainer. Believe it or not, Veevee Volley is the move Eevee will always use when its Partner Power is activated in battle. Furthermore, Eevee will also be able to learn Buzzy Buzz (an Electric Type Attack that causes paralysis), Bouncy Bubble (a Water Type Attack that heals Eevee by 50% of the damage it inflicts), and Sizzly Slide (a Fire Type Attack that causes the opponent to become burned).
