LET'S GO AGAIN
Looking at my two latest avis on the forum...
Mega Hitmonchan
Type: Fighting Ability: Scrappy
HP: 50
Attack: 105 -> 130 (+25)
Defense: 79 -> 120 (+41)
Special Attack: 35
Special Defense: 110 -> 119 (+9)
Speed: 76 -> 101 (+25)
This Mega Hitmonchan is bulky, which is the point of its creation. Iron Fist was lost as its ability, forcing Hitmonchan to lose power on moves like Drain Punch and Mach Punch, but a boost in Attack compensates for that. Instead, Hitmonchan now received Scrappy as its ability, giving it the chance to now hit Ghost-types with its Fighting-type moves as well, which is a major boost because a lot of Ghost-types were able to wall Hitmonchan before. Moreover, Mega Hitmonchan is would be the only Scrappy Rapid Spinner, giving it the chance to remove hazards at will, and not being walled by Ghost-types in the process.
However, even with Scrappy, Mega Hitmonchan is still vulnerable to Ghost-type Pokémon, as a lot of them carry Will-O-Wisp, which completely cripples it. The point of Scrappy is that Ghost-types don't have a free switch in Hitmonchan anymore, and that Rapid Spin can be used at all times.
While a Rapid Spin set is a possibility, with these stats Mega Hitmonchan can pull off Bulk Up sweeps as well.
And of course, if we have Hitmonchan.
Mega Hitmonlee
Type: Fighting/Dark Ability: No Guard
HP: 50
Attack: 120 -> 145 (+25)
Defense: 53 -> 63 (+10)
Special Attack: 35
Special Defense: 110 -> 130 (+20)
Speed: 87 -> 132 (+45)
I might have gone a little overboard with the Speed and Attack. Oh well. I got the idea of a Fighting/Dark-typed Mega Hitmonlee... Man, I dunno even when. It just hit me, and then I remembered that it actually had Knock Off. Together with the moves High Jump Kick and Stone Edge, both of which will always hit now due to No Guard, Mega Hitmonlee has access to a very powerful movepool.
No, really. Those moves hit hard, especially combined with the fact that Mega Hitmonlee also gets Bulk Up. Sadly no Swords Dance, but hey. Does this thing need it. While it gets hit hard by some priority moves (Mach Punch, Gale Wings), Mega Hitmonlee can also shrug off one of the most prominent priority moves (Sucker Punch) without a problem.
Hitmonlee already had some troubles with Fairy, but thanks to its new typing, that problem skyrocketed. Though with the help of teammates and possibly Iron Head, Mega Hitmonlee could be able to deal with it.
