Ugh. DragonHeaven seems like it refuses to load properly for me as of late, so that's fun, almost as fun as Daylight Savings Time continuing to unnecessarily exist. Also, whoops. Somehow forgot that anaconja already did Electric/Fire Electric Surge Manectric-Mega, so I guess I won't be submitting anything for that entry at this point, though I do wish that one had Will-o-wisp too:
Name: Medicham-Mega
Type: Fighting/Psychic
Ability: Contrary
Stats: 060 HP / 090 Atk (+30) / 090 Def (+15) / 080 SpA (+20) / 080 SpD (+05) / 110 Spe (+30)
New Moves: Close Combat, Psycho Shift, Stored Power, Superpower
Description: While this and Pidgeot-Mega are the mons this time that I'll probably vote for the originals for among my votes, I did at least want to try to submit things for them, and this one was
way easier to think of compared to Pidgeot-Mega even if I had to add more moves than I would have liked. Contrary allows me to stick rather close to the "Mega with seemingly underwhelming stats that gets pretty out of hand (in theory)" idea that the original has and is also rather funny against Intimidate on a physical attacker. Contrary Superpower is self-explanatory, so I'll just point out that the seemingly redundant Close Combat is there more for Stored Power than anything else, and Psycho Shift is just there merely because I've always found it neat and super underused, in part because so few things get it. This should be fine as far as balance goes despite having Drain Punch between Ghosts, unaware Clefable, and 110 Speed not actually being that fast on top of it needing like two turns to become really threatening instead of being immediately threatening like regular Medicham-Mega.
Name: Absol-Mega
Type: Dark/Ground
Ability: Aeromancy = This Pokémon's Attack is raised by one stage when hit by a Flying attack; Flying immunity.
Stats: 065 HP / 150 Atk (+20) / 075 Def (+15) / 075 SpA / 075 SpD (+15) / 125 Spe (+50)
New Moves: Earthquake, Earth Power, Spikes, Tailwind
Description: Gods, as much as Absol-Mega is one of the few mons whose Mega design I like visually, the stats on regular Absol and its already existent movepool make it so damn hard to balance given how utterly frail it is. Took forever to think of an ability that seemed good enough without broken...and then Yoshiblaze essentially did the same idea I had. Yay. Oh well, like with Alazakam-Mega, at least someone did it. As for this "backup", I was vaguely considering just giving it Wind Rider, but that'd be kind stupid with Tailwind even with its fraility and newfound weakness to no less than three forms of priority. As it is now, however, it does block Defog, which is a niche in and of itself even if Zapdos tends to use a non-STAB move, meaning it doesn't hilariously auto-wall it as it might otherwise. The type and ability also is a decent if still frail check to the new Aerodactyl-Mega's "vintage" Hurricane without being weak to Earthquake (though it sure as hell doesn't like it either with that HP). Not much else to say about it, honestly.
Name: Pidgeot-Mega
Type: Fairy/Flying
Ability: No Guard
Stats: 083 HP / 080 Atk / 080 Def (+05) / 135 SpA (+65) / 080 SpD (+10) / 121 Spe (+20) {a.k.a. the official stat changes)
New Moves: Moonblast, Play Rough
Description: The second of the two that I'm doubtless going to vote for the original among my votes, especially since MegaFlareon surprisingly took my idea days ago which is apparently borderline broken anyway. Whoops. Anyway, due a lack of real ideas otherwise, this is mostly just the creatively bankrupt "Fairy glow-up" along that's almost as lazy as the same lines of "give something Regenerator" since the original Pidgeot-Mega is so close to being OU material as it already is despite its sparse movepool. So I figured I would give this the bustedness of Moonblast over the more mundane Dazzling Gleam mostly just to spitefully stick it to Togekiss because honestly screw that thing, forever and always.
