Your Mega Zapdos sucks tbh. All Mega's seem to stick to their main attacking type. (Unless they get two Mega's.) But you give Zapdos a bigger boost on it's attack then it's special attack but still keep it far inferior.
Plus you give it's speed one of the lower boosts as well even though it's the fastest out of the legendary birds and a lighting type that are generally fast.
Sorry but it just kinda sucks. The way the stats should be put out would be much better like this.
HP - 90
Attack - 100
Defence - 100
Sp Attack - 155
Sp Defence - 105
Speed - 130
As for abilities you made them kinda generic. These pokemon are not even weather type legends. Leave the changing weather to them or it kinda makes them pointless.
