Walkthrough:Pokémon Legends: Z-A/Part 29

The true final boss

Once you have caught both Yveltal and Xerneas, L will approach you as you return to Hotel Z. They ask to battle you to prove that you are worthy as a trainer. This launches Main Mission 42: To Keep the World in Balance. He is the strongest trainer we’ve fought yet with a level 78 Pyroar, Sableye and Florges, a level 79 Noivern and Garbodor, and a level 80 Mega Gyarados. It’s important to remember that Gyarados changes types when it Mega Evolves to Water/Dark-type.

Once you have defeated L, Zygarde will approach you. L tells you that it wishes to battle you in the place where Prism Tower once stood. It will be standing in the middle of Wild Zone 20, and you need to talk to it in order to initiate the battle.

The fight against Zygarde takes part in an arena much like the ones for the Rogue Mega Evolution fights. It is level 84, and starts out in its 10% forme, but it’s important to remember that if you are KOed during any part of the fight you will have to restart the fight again from this forme. We recommend a high level Ice-type with at least three Ice-type moves, as these are quadruple effective against Zygarde. You want to be firing these off consistently to keep up the pressure.

When 10% forme goes down it transforms into 50% forme. This one is stronger and bulkier than the first form, so it’s more difficult to take down. You can continue to use your Ice-type here, but remember to recall it when it uses its charge attack. This will see green light burst out from cracks in the floor across the arena that you need to run from to dodge.

The final form is Zygarde Complete, and this one acts more like a Rogue Mega Evolution in that standard moves do negligible damage compared to Plus Moves and Mega Evolved Pokémon. An Ice-type like Mega Froslass is ideal, but higher leveled Pokémon like Meganium will be stronger if you haven’t trained a Froslass. Zygarde Complete has two charged attacks. The first has Zygarde rise above the arena, and draw a Z on the floor with one small safe zone. The second sees Zygarde go to the center of the arena, with light bursting through the floor in circles moving inwards twice in a row. You need to stand in the middle and move towards the edge to avoid this.

Once the Complete Form is taken down you have your chance to catch Zygarde You can use any ball, and it is guaranteed to be caught. However, you do need to move close to Zygarde in order to catch it, like with regular wild Pokémon. Once caught L will speak to you for the last time, saying that he is going to dedicate his life to making the world a better place, and will be leaving Lumiose City forever.
