Actually, because of me
Nah jk. Alakazam already got an increase of Sp.def from 85-95 in Kalos so logically Alakazam only got 90 because of that +10 in sp.def.
>It is because normal Alakazam got a +10 boost already
If you look at Alakazam in Gen 5, you'll notice his Special Defense is 85.
However in Gen 6 it is 95. Alakazam is the only Pokemon with a mega-evolution who got a boost to stats in normal form as well. This is the most plausible explanation, as with the +10 and the +90, Alakazam ends up at +100, like all other megas. Otherwise he'd be at +110.
>So basically when you said, GameFreak should have treated him like the others, in the end they did. Mega Alakazam technically gets the exact same boosts - just it gets +10 before mega-evolving.
Directly ripped from here. Thanks Sempi.
Hope I helped!
