Rogue Mega Rush

After capturing Rayquaza, a new mode will unlock in Quasartico Inc.. This mode is the Rogue Mega Rush mode which allows for you to face off against all the Rogue Mega Evolution Pokémon you faced before, but with a twist; you have to face all of them in order, from Mega Absol through beyond Mega Rayquaza and finally to Zygarde

There are a few stipulations to the matches however. You cannot use items from your bag during this, which means no using items such as Revives or Potions in the match. This doesn't mean you have to go through all 27 matches without healing, however. You can heal your entire team three times and only three times.

All the Pokémon you face are Level 100, and unlike in the story you face them alone, but there is no time limit.

After completion, you will get a number of the amount of Pokémon that you managed to defeat during the Rush, and the time it took you to get that far.

If you manage to defeat all of them, you will receive the special title "Mega Rush Master"
