Legal, but nobody plays it

Heracross is legal in Regulation M-B and did not appear often enough on the ladder to produce usage statistics. It is legal and simply out of favour, which makes it unmeasured rather than unusable.

The Pokémon itself

Heracross is number 214 in the National Dex, a Johto Pokémon, Bug and Fighting with a base stat total of 500 — 125th of the 234 Pokémon legal in this regulation. Its best stat is Attack at 125, 24th in the format; its weakest is Sp. Atk at 40, 230th. It can have Swarm, Guts and Moxie. The Champions module tiers it UU.

It has no evolutions on either side; what you see is the whole line.

What gets through

As Bug and Fighting, 4 of the eighteen attacking types do extra damage to it, and Flying lands for quadruple. It resists 5. The board above has all of it. No other legal Pokémon has this typing.

What threatens it

Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is computed, not measured: the most-played Regulation M-B Pokémon carrying a damaging move of a type Heracross takes extra damage from.

Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
Whimsicott — Moonblast (Fairy, ×2), on 93.9% of its sets
Farigiraf — Psychic (Psychic, ×2), on 54.4% of its sets
Floette-Mega — Dazzling Gleam (Fairy, ×2), on 95.9% of its sets
Pelipper — Hurricane (Flying, ×4), on 98.1% of its sets

Speed and weight

At level 50 with a boosting nature and full investment, Heracross reaches 150 Speed; left uninvested with a neutral nature it sits at 105. Invested, it outruns 11 of the 20 most-used Pokémon in the regulation when they are invested too — which is the comparison that decides who moves first.

It weighs 54 kg, so Grass Knot and Low Kick hit it for 80 base power. That is a real consideration in a format where both are common.

Its move pool

Heracross learns 99 moves in the Champions data. 63 of them do damage, across 11 of the eighteen types, and 19 share a type with it and so get the same-type bonus. Its hardest-hitting same-type move is Focus Punch at 150 base power. It also has priority: Upper Hand at +3, Feint at +2 and Vacuum Wave at +1.

That pool is what the team builder reads from when you seat it, and the damage calculator will take it as the attacker with the form already chosen.
