Pokemon GO Mega Charizard X or Y can be a difficult decision for some trainers. Fortunately, we have all the information available to explain the pros and cons.
Niantic Labs let trainers have a blast with its Mega-September release, finally implementing mega-evolutions into Pokemon GO. Only a few Pokemon have been gifted the mega-treatment so far, including the Kanto starters Charizard, Venusaur, and Blastoise. Of the three, Charizard seems to be the one with the most debate. We assume having two forms to pick from could do that to you.
Pokemon GO Mega Charizard X or Y: Which to Choose
Mega Charizard X changes its typing from fire and flying to the often discussed fire and dragon. It has a CP ceiling of 3850, an attack stat of 273, defense of 213, and stamina of 186. In large groups, it has the capability to boost its teammates' fire and dragon-type moves.
Mega Charizard Y keeps the fire and flying dual-typing of its original form. It has a CP ceiling of 4455, an attack stat of 319, defense of 212, and stamina of 186. Trainers report that this form is the second-strongest of all the fire-type DPS options.
Despite its more favored form, Mega Charizard X is simply outmatched by Mega Charizard Y. While the dragon-type change is an interesting tweak, this, unfortunately, does nothing for Charizard as a whole aside from answer fan debate. Y completely surpasses it in this Pokemon's original fire-type offensive damage niche. X becomes quickly outclassed by other mega dragon-types like Mega Rayquaza when placed in the same category.
Ultimately, Mega Charizard Y is the best choice.
