Heatmor, Win Less
Heatmor@Choice Scarf
Modest nature
Flash Fire
252 Sp. Atk/252 Spd/4 HP
~Flamethrower/Fire Blast
~Focus Blast
~Hidden Power (Ghost)
~SolarBeam
It's a sad state of affairs for Heatmor, it sure is. Outside of Round and its other Fire moves, this is, without exaggeration, its entire Special movepool. Flamethrower is for STAB, though Fire Blast is a more powerful option if you like taking risks. And if you're using Heatmor in the first place, you like taking risks Focus Blast and HP Ghost have unresisted coverage, and well, it was either SolarBeam, Round, or another Fire move for that last slot. SolarBeam at least gives Heatmor a decent chance on or against a sun team.
Item does what it can to salvage Heatmor's pitiful Speed, because GameFreak couldn't even be bothered to give this thing Flame Charge. I mean, what the hell? Ability is really the only useful one currently legal.
A Claws In My Contract
Heatmor@Choice Band
Brave nature
Flash Fire
252 Atk/252 HP/4 Def
~Shadow Claw
~Aerial Ace
~Bug Bite
~Return
Heatmor sports a respectable base 97 Attack stat. Its physical movepool, on the other hand, leaves a freakishly large amount to be desired. No physical Fire moves at all. No Fire Punch, no Flame Wheel, no Flare Blitz, no Blaze Kick, not even Flame Charge, which makes Heatmor the ONLY Fire-type that can't learn it in the entire game, while stuff like frickin' Zebstrika get the move! Ahem. That said, this Heatmor's more for a Trick Room team, though good freakin' luck with it there. Shadow Claw, Aerial Ace, Bug Bite, and Return are its best moves. Please take a moment now to let the hopelessness of that previous sentence sink in, as I mentioned "Aerial Ace", "Bug Bite", and "best moves" in the same sentence without referring to Scyther or Scizor, or indeed anything with Technician.
Item is obvious, ability is obvious.
Defendmor
Heatmor@Leftovers
Careful nature
Flash Fire
252 HP/128 Def/128 Sp. Def
~Stockpile
~Will-O-Wisp
~Protect
~Wrap
It's far from ideal, given its facepalm-worthy 85/66/66 defenses, but Heatmor can attempt to go defensive. Stockpile ups its mournful defenses, Will-O-Wisp means extra help on the physical side of things, Protect allows for extra Leftovers recovery, and Wrap is for extra damage and stopping the opponent from withdrawing their crippled Pokémon
Item, ability, yadda, yadda, yadda.
Other options:
*Heatmor can learn Hone Claws, but none of its physical moves are really that wanting for better accuracy. Could be fun to use with Inferno, but almost definitely not too effective.
*Night Slash and Sucker Punch are decent options, but Heatmor already gets Shadow Claw as a TM, making Night Slash a tad redundant, and Sucker Punch is situational. Heatmor can't afford to fail even more than it already does.
Abilities:
*Gluttony: Heatmor consumes its pinch berries at 50% health. Useless, as not only is there no pinch berry in existence that can help Heatmor that much, but in what reality is Heatmor gonna be left at 50% health anyway?
*Flash Fire: When Heatmor takes a Fire move, its own Fire moves gain power. It is also immune to Fire moves. The better of Heatmor's abilities, as it does at least give it an immunity. Sure, it's an immunity to its own type which it resists anyway, but better than nothing.
*White Smoke: Heatmor's Hidden Ability. Not legal yet, but it's not really an issue. Heatmor's stats can't be lowered by its opponents. Heatmor's own actions, however, will still lower its own stats, which means no Overheat spammage. Nobody's gonna try to lower Heatmor's stats anyway, opting instead for the quick and easy KO.
Partners:
Smashpassing, Wish support, Rapid Spin, Magic Bounce, and in the case of the Choice Scarf set, Drought. And even then, there's still the matter of Heatmor's Arceus-awful movepool to contend with.
Counters:
Just play as normal. Chances are at least two of your Pokémon can function as a Heatmor counter.
Opinion:
An awesome concept of a Pokémon gone horribly wrong. I love Heatmor's design, but its stats are mediocre, and it's like they weren't even trying when they slapped its movepool together. Seriously, Heatmor is the only Fire-type on the face of the planet to not learn Flame Charge. What were they smoking?
Prediction for next week:
