EVs: 252 HP / 4 SpA / 252 SpD or 252 HP / 176 SpD / 80 Spe
Calm Nature
- Lava Plume
- Stealth Rock
- Toxic/Roar/Protect

#Moves
Lava Plume is a great STAB and has a burn damage. Stealth Rock is to make Steel’s life easier sweeping, steel always enjoys the hazards on the opponents field. Protect is to gain a little HP by leftovers, aswell as for HJK users. Also able to scout what your opponent uses. Roar is for mons that set up, and Toxic is if you cant really hit anything with Earth Power/Lava Plume, to make them lose damage and easier for the other mons to take out. Lastly, Earth Power is for other fire mons.
#Set Details
Heatrans usage is 98.9% on steel, it helps steel alot with flash fire to take on fire moves which things on your team such as skarmory, ferrothorn, doublade and scizor don’t appreciate. It is also a reliable stealth rocker, and deals with threats such as Victini and opposing Heatrans. Sometimes people tend to use 80 Speed to outspeed other heatrans and mandibuzz. Leftovers help it out with regaining HP, which protect is also used at times, yet at times people tend to run Air Balloon if their team is too weak to ground
#Usage Tips
One of the main things you can do with heatran is switch in on a fire move to boost up your fire moves with flash fire. On steel, fire mons such as Victini, Entei, Darmanitan and Chandelure are great threats to steel. Heatran basically covers those threats, and since they all tend to be choiced items, you just hit earth power, or its your chance to set up stealth rock if you did not do so already. Heatran also likes a physical defensive partner such as skarmory and doublade for things like Terrakion, Heracross and Medicham.
#Team Options
Skarmory is the best mon on steel to form a defensive core with heatran. Skarmory is weak to fire type attacks in which heatran is immune to, and heatran is weak to ground types which doesn’t have any affect on Skarmory. These two mons can also form a hazard stack team since Skarmory learns spikes and heatran learns stealth rock. Since Steel appreciates the hazards, mons like Doublade and Bisharp help alot since Doublade isn’t affected by rapid spin and Defog raises bisharps attack, not only do these mons help with hazard control but they both get access of swords dance which also helps late game sweeps, not to mention Doublade is also immune to fighting type attacks
Lava Plume, Toxic, and Earth Power are necessary IMO, as without Earth Power Heatran can't check Fire types like its supposed to and you're probably going to get 6-0d by another Heatran lol. Toxic is pretty much necessary on SpDef tran since you're really weak and without it you can't even beat Zard-Y or Volcarona, one of the biggest things heatran's supposed to do. (mention what these moves do in moves paragraph)
This makes the set Lava Plume | Earth Power | Toxic | [Stealth Rock / Protect / Roar]
Change the order in the moves paragraph as necessary, mention that Heatran is a good user of Stealth Rock, but if Skarmory or Ferrothorn sets Stealth Rock then Heatran appreciates the freed up moveslot. Also mention Taunt in the moves paragraph as a way to stop Pokemon like Mandibuzz and Venusaur from healing up, or Zapdos from defogging. Mention Stone Edge to ohko zard y and volcarona.
Don't say "Lava Plume... has a burn damage" say "Lava Plume also has a chance to burn"
Don't say "Stealth Rock is to make Steel's life easier sweeping" say "Stealth Rock helps other Steel-type Pokemon sweep easier. Heatran is particularly a good user of Stealth Rock as it can force out Mega Sableye."
Try to avoid using all these short sentence fragments, it makes it seem like the paragraph is all over the place. Something like "Also able to scout what your opponent uses" needs more integration into the paragraph.
Now, Heatran probably has the freedom to use whatever EV spread it wants on this spread with however much speed creeping it needs, but quite honestly it doesn't need any speed at all if it doesnt use taunt. I would make the only listed spread
248 HP / 8 Def / 252 SpD with a calm nature. 248 hp is an odd number for stealth rock.
Mention in set details that you should use more speed if using taunt, in particular
44 speed for 16 speed Mandibuzz (not 80) and 16 speed Mega Venusaur and
204 speed for 16 speed Zapdos and adamant Bisharp. Get rid of the specific usage mention in set details, that % changes every month and is guaranteed to be outdated.
Sorry but if you're going to be writing a lot of these you need to go over your writing and make sure it makes sense first. Reword the set details at the end, try saying stuff like "Air Balloon can be used to deal with opposing Heatran better and to give another immunity to Ground-type moves" instead of "yet people tend to use air balloon"
Remove mentions of good teammates in usage tips. In usage tips, mention how Heatran is a good pivot into most special moves, like Mega Manectric's Thunderbolt.
Mention Ferrothorn as a good partner to take on water moves in team options, and mention that it can also set up spikes in combination with heatran's stealth rock
EDIT: also didnt notice this but remove the air balloon slash. keep it in set details only, since the spdef set appreciates leftovers way too much to use balloon
