Why would we need more mega Charizard and mewtwo

Why the heck are Charizard and Mewtwo here instead of Delphox and Chesnaught?

Mega shuckle? (255 atk)??

0defense??

I also want Mega Charizard Z and A

We need Mega Charizard A-Ω

Ah yes, Grininja. Covidknight.

We don't need more Mega Evolutions for Charizard and Mewtwo. They're already super powerful, their Megas just aren't needed.

Covidknight?

Covid-knight he has COVID-19?

"Corviknight"

Grininja?

Grin-ninja damn he has big chinn!!!!

"Greninja"

Gen 6 starters need mega the most and the starters of the game whatever they pick
