Shadow Heatran

Shadow Heatran is a top tier Fire attacker, boasting not only excellent DPS, but also great survivability. Thanks to its impressive bulk and seemingly endless resistances, Shadow Heatran can can sometimes stick around on the battlefield approximately twice as long compared to glassier Shadow Fire-type options such as Chandelure or Darmanitan - while still outputting the same DPS.

Best PvE Moveset

• Fire Spin and Magma Storm* is Heatran’s optimal set.
• Fire Blast is a bit behind in DPS, but also less efficient as a 1-bar move. It can be Heatran's best option in Party Play due to its high damage.
• Bug Bite is the worse move in the situations where Heatran is useful. However, it can charge up Party Power more quickly than Fire Spin, which can make it more useful in some matchups.
• Iron Head is better for attacking Fairy-types.
• Stone Edge has no role on gym or raid offense.
• Flamethrower is objectively worse than Magma Storm*, but it's a fine non-Elite substitute with a close overall performance

Fire Spin has greater damage and energy than Bug Bite and benefits from STAB.

Magma Storm is recommended due to its cheap cost and STAB. Stone Edge grants the most overall coverage, nailing several Flying-type Pokemon that may not mind Heatran's Fire-type attacks. Earth Power can be used to dispatch opposing Dialga and Heatran more reliably, but its coverage is somewhat redundant otherwise. Iron Head benefits from STAB and costs the second least amount of energy, but its DPE is poor and its coverage isn't amazing. Flamethrower is outclassed by Magma Storm.
