In the anime it was worse, they gave her character arc to an OC. Korrina should have been the character who introduced us to the Mega Evolutions, traveling and learning from each one of them, and even having a team with Mega Fighting Pokemon at the end and having to learn to adapt to each change. For example, an M-Blaziken struggling with its speed boost, an M-Medicham not knowing how to handle its extra "arms," an M-Lopunny struggling to adapt to its new dual type, and an M-Heracross only charging head-on.

"But you can only have one Mega Pokemon" I'm not saying she uses them all at the same time, but rather giving each Mega Evolution a mini-arc with its pros and cons. Plus, her grandfather has an M-Lucario, an M-Blaziken, and an M-Alakazam, which is why he's the Mega Evolution guru.
