Didn't see one of these in the catalog. By now ya'll know the drill - come up with BSTs for a mega evolution of your favorite Pokemon. Remember, it's a +100 stat boost and stat changes usually add or subtract +10 or -10 at the minimum. As always, remember that HP can't be changed. For fun, post damage calcs and theorize how your mega would perform in the current OU metagame (or other metas; Smogon's just the easiest to work with because so many people know it).

Mega Feraligator
Water/Dark
Ability: Strong Jaw
HP: 85
Attack: 105 > 145 (+50)
Defense: 100 > 120 (+20)
Special Attack: 79 > 89 (+10)
Special Defense: 83 > 93 (+10)
Speed: 78 > 88 (+10)

Attack is now decently high and it can tanks hits a bit better now. Arbitrary Special Attack boost (because GF would do that), and a nice speed boost that lets it outspeed more after a Dragon Dance. Strong Jaw plus access to Crunch and Ice Fang let it hit fairly hard off its high base Attack. It acts as a pretty good Mega Charizard counter. STAB Strong Jaw Crunch absolutely decimates.
