In Pokemon: Let's Go, Pikachu, New Wild Pokemon Battle Mechanics see players having to now simply capture a Pokemon without having to first lower their Hit Points through battling like previous Mainstream Pokemon Games. However, in regards to Legendary Pokemon Encounters within the game, there are actually a different set of mechanics altogether. Instead of being able to simply try to capture these Legendary Pokemon, player will first have to battle and defeat them within a certain amount of time. After doing so, only then will they be able to attempt to capture them like other Wild Pokemon found within the game.
