Mega Steelix Best Moveset in Pokemon GO (2026)

Mega Steelix is one of the most defensively imposing Pokemon in the game, but that fortress-like Defense stat comes at a direct cost to its offensive output. As the Mega Evolution of Steelix, this Steel/Ground behemoth reaches a max CP of 4,149 at Level 50 — backed by a base Defense of 327, the second highest among all Mega Evolutions. The problem for raid trainers is straightforward: Pokemon GO rewards offense, and Mega Steelix’s base Attack of 212 leaves it trailing behind dedicated Steel-type attackers like Mega Metagross, Shadow Metagross, and Zacian (Crowned Sword).

That said, Mega Steelix has a clearly defined role and it performs that role well. It provides a Mega Boost to all Steel and Ground-type moves used by raid teammates — meaning even if Mega Steelix is the weakest attacker in your lobby, it is quietly buffing everyone else’s damage. Combined with its extraordinary bulk and 10-type resistance profile, it can stay in battle long enough to keep that Mega Boost active even under heavy fire.

For PvP, the story flips entirely. Mega Pokemon cannot participate in standard Go Battle League (GBL) matches, so the PvP analysis below applies to regular Steelix. And Steelix in PvP is genuinely excellent — particularly in Ultra League where it climbs into the top 50 overall. The moveset decisions apply equally whether you are playing the Mega or the standard form.

This guide covers every move available to Mega Steelix, the optimal moveset for raids and PvP, Max Battle recommendations, and everything you need to get the most from this armored giant in 2026.

Mega Steelix Base Stats

Fast Moves

Mega Steelix has access to three fast moves, each serving a distinct purpose. Iron Tail leads in raw damage output while Thunder Fang’s rapid energy generation makes it the preferred option for PvP. Dragon Tail sits between the two and is worth considering when Iron Tail is resisted.

DPS = Damage Per Second | EPS = Energy Per Second

Charged Moves

Mega Steelix’s charged move pool includes two STAB options with strong damage and two coverage moves that provide utility, particularly in PvP. Shadow variants carry Frustration in place of a coverage slot; Purified variants can access Return.

Recommended Moveset

Best Moveset for Raids: Iron Tail + Heavy Slam

Iron Tail delivers the highest fast move damage output available to Mega Steelix, and Heavy Slam’s 50-energy cost means it fires noticeably more often than Earthquake. Both combinations produce the same overall DPS of roughly 13.0, but Heavy Slam’s lower energy threshold results in more consistent charged move usage within a raid’s time window.

There is one meaningful exception: if your raid group is running a Ground-type squad (Groudon, Excadrill, Garchomp), switching Heavy Slam out for Earthquake activates the Ground-type Mega Boost for all Ground-move users on your team. The decision is about team composition rather than Mega Steelix’s individual DPS. If the rest of your lobby is already using Steel-type attackers, Heavy Slam is the correct default. If they are Ground-type specialists, run Earthquake instead.

Best Moveset for PvP (Regular Steelix): Thunder Fang + Psychic Fangs + Crunch

In Go Battle League, Thunder Fang’s energy generation is what makes Steelix threatening. At 13.3 EPS it charges moves quickly, allowing repeated Psychic Fangs and Crunch pressure before opponents can respond. The 45-energy cost on both charged moves means Steelix can access them two or even three times in a single match against a defensive opponent.

Psychic Fangs applies a Defense drop to the opponent on every use, and multiple stacks accumulate. What starts as neutral damage output against a Steel-resistant target becomes significantly more threatening by the third or fourth Psychic Fangs in a long match. Crunch handles opponents that resist Psychic-type damage and acts as the closing move against lower-HP targets.

Iron Tail + Heavy Slam is technically viable in PvP but is not recommended. Iron Tail’s 6.0 EPS is too slow for GBL’s pacing, and Heavy Slam’s Steel typing frequently lands neutrally rather than super effectively in the metas where Steelix is most played.

Raid Performance

As a raid attacker, Mega Steelix sits in B-Tier among Steel-type attackers — ranked approximately 40th on the Gamepress attacker tier list. Its 327 base Defense allows it to survive longer in raid lobbies than almost any other Mega Evolution, but the 212 Attack cap means raw DPS output is modest compared to the Steel-type elite. Where dedicated Steel attackers like Shadow Metagross or Zacian (Crowned Sword) maximize personal damage, Mega Steelix maximizes team uptime.

The Mega Boost mechanic is the real argument for bringing Mega Steelix to a raid. When it is the active Mega Evolution, all Steel and Ground-type moves used by your raid partners receive a damage increase. The boost remains active even during Mega Steelix’s faint animation, provided it was the most recently active Mega in the lobby. For Steel-heavy squads targeting Ice, Rock, Fairy, or Flying-type raid bosses, the boost contribution can exceed what a more fragile but higher-DPS Mega would have provided over the same time window.

Recommended alternatives for higher personal Steel-type DPS include Shadow Metagross, Mega Metagross, and Zacian (Crowned Sword). Use Mega Steelix specifically when you want a long-lasting Mega Boost anchor — one that stays active through multiple raids in a session without needing frequent revives.

Mega Steelix is vulnerable to Fighting, Fire, Ground, and Water-type moves at 160% damage. These weaknesses come up most often when running Steelix into matchups where Ground or Water-type moves are common raid boss tools. Plan accordingly.

PvP Viability

Important note: Mega Steelix cannot be used in any standard Go Battle League format. The analysis below covers regular Steelix, which uses the same moveset options.

Great League (1,500 CP Cap)

Steelix is viable in Great League, ranking approximately 151st out of 1,089 eligible Pokemon on PvPoke. At 1,500 CP it sits around Level 27–28, still carrying substantial bulk relative to other Great League picks. The Steel/Ground typing generates 10 resistances and complete immunity to Poison and Electric damage, making Steelix a reliable check against a wide spread of attackers.

The challenge in Great League is the prevalence of Fighting and Ground-type coverage moves, which hit Steelix for 160% damage. Medicham, Galarian Stunfisk, and Water-type staples all pressure Steelix hard. It works best in limited formats or cups with fewer of those specific threats. In open Great League, expect mixed results depending on team composition and opponent pool.

Best Great League moveset: Thunder Fang + Psychic Fangs + Crunch.

Ultra League (2,500 CP Cap)

Ultra League is where Steelix genuinely excels. It ranks 43rd overall out of 802 eligible Pokemon — top six percent — and sits comfortably in the competitive upper tier. At 2,500 CP, Steelix is around Level 40, and its Defense stat creates a near-impenetrable wall for Pokemon that cannot hit it super effectively.

Key Ultra League wins include Togekiss, Cresselia, Registeel, Giratina (Altered Forme), and most Dragon-type flex picks. Its bulk means it can absorb two or three charged moves from neutral attackers, forcing opponents to expend shields just to secure the KO. Repeated Psychic Fangs Defense drops compound this pressure — multiple applications erode even resistant targets faster than the flat DPS numbers suggest.

Shadow Steelix performs even better in Ultra League due to the 20% Attack bonus, though survivability decreases proportionally. For trainers investing in a Steelix specifically for PvP, Ultra League is the target environment.

Best Ultra League moveset: Thunder Fang + Psychic Fangs + Crunch.

Master League (10,000 CP Cap)

Regular Steelix maxes out at approximately 2,414 CP at Level 40 — well below the 4,000–5,000 CP range where Master League’s top threats operate. Its Defense stat helps it absorb a few extra turns against neutral attackers, but Steelix cannot win the damage race against Master League’s dominant picks.

Steelix is not competitive in Master League. Shadow Steelix performs slightly better due to the attack multiplier but still falls short of meaningful results. For a Steel/Ground-type option in Master League, Zacian (Crowned Sword), Dialga, and Garchomp are the appropriate choices.

Max Move Recommendations

Regular Steelix can be Dynamaxed in Pokemon GO’s Max Battles, where its fast move determines the type of Max Attack it uses during Dynamax turns. Selecting the right fast move for your intended Max Battle role is therefore a meaningful decision.

When Dynamaxed, Steelix’s fast move generates the following Max Attack:

• Iron Tail → Max Steel Spike (Steel-type): Deals Steel-type damage and raises your entire team’s Defense. This is the recommended choice — STAB damage output plus a team-wide DEF buff makes every subsequent turn safer for all four trainers in the lobby.
• Dragon Tail → Max Wyrmwind (Dragon-type): Deals Dragon-type damage and lowers the boss’s Attack stat. Useful for managing high-attack bosses during the Dynamax window, but gives up STAB and the team DEF benefit.
• Thunder Fang → Max Lightning (Electric-type): Deals Electric-type damage and boosts your team’s Speed. Speed boosts have minimal value in Max Battles’ turn-based structure. This is the least useful option for Steelix in Max content.

The recommended Max Battle setup is Iron Tail with either Heavy Slam or Earthquake as the charged move. Iron Tail generates Max Steel Spike, which provides STAB damage and the team Defense buff. Charged moves in Dynamax form always convert to either Max Guard (Defense boost) or Max Spirit (HP recovery) rather than their standard effects, so the charged move choice matters less during Dynamax turns specifically.

FAQ

Is Mega Steelix worth Mega Evolving for raids?

Yes, but specifically for the Mega Boost rather than personal DPS. Mega Steelix activates a damage bonus for all Steel and Ground-type moves used by your raid team, and its extraordinary bulk keeps that bonus active longer than most fragile Mega alternatives. If you are running a Steel-type squad against Ice, Rock, or Fairy-type raid bosses, Mega Steelix is a legitimate support anchor. As a pure personal DPS contributor it ranks B-Tier among Steel attackers — adequate but not elite.

Can Mega Steelix be used in Go Battle League?

No. All Mega Evolutions are excluded from standard Go Battle League formats including Great, Ultra, and Master League. The moveset you develop for best PvP performance will apply when Steelix reverts to its standard form, but Mega Steelix itself cannot compete in GBL. In PvP, regular Steelix performs best in Ultra League with Thunder Fang, Psychic Fangs, and Crunch.

Should I use Iron Tail or Thunder Fang on Mega Steelix?

It depends on the content. For raids and Max Battles, Iron Tail is the correct choice — it provides higher DPS, benefits from STAB, and generates Max Steel Spike which also buffs your team’s Defense. For PvP with regular Steelix, Thunder Fang is the right pick because its 13.3 EPS charges moves far more quickly than Iron Tail’s 6.0 EPS, allowing Steelix to pressure opponents with Psychic Fangs and Crunch from the first exchange. The same Mega Steelix cannot be optimal for both at once — choose based on which content you prioritize, or keep two Steelix with different movesets.
