Where is Zekrom in Pokemon Rumble Blast after you beat the game?

Zekrom is not available in Pokémon Rumble Blast after you beat the game. Zekrom is a post-game event Pokemon in Pokémon Rumble Blast. This means you can only get it by completing specific actions after finishing the main story:

1. Beat the game: You need to finish the main story mode and become the Rumble Champion.

2. Collect all 600 Pokémon: You need to collect all 600 Pokémon available in the game. This is a massive undertaking and involves completing side quests, defeating certain enemies, and purchasing some from the shop.

3. Complete the "Mega Evolution" quest: After collecting all 600 Pokémon, a special quest called "Mega Evolution" will unlock.

4. Defeat Zekrom: You will then need to face and defeat Zekrom in the "Mega Evolution" quest.

Only after successfully completing all of these steps will Zekrom become available in your Rumble Blast collection.
