Is Regigigas Good?

No, Regigigas is severely crippled by its Slow Start ability, making it practically unviable in standard play. Relegated to the ZU tier in Scarlet and Violet, it acts as a very niche physical attacker. Halving its Attack and Speed for five turns completely ruins its massive raw stat potential.

Slow Start ensures Regigigas remains a massive liability rather than a legendary threat.

Rating 2/10 · Tier ZU (Scarlet/Violet) · Role : Niche Stallbreaker / Physical Attacker

Strengths

• Massive natural bulk allows it to survive neutral hits comfortably.
• Incredible base Attack and Speed once Slow Start finally deactivates.
• Access to excellent utility and STAB moves like Knock Off and Body Slam.

Weaknesses

• Slow Start halves Attack and Speed for five agonizing turns.
• Switching out resets the Slow Start counter entirely.
• Extremely vulnerable to common Fighting-type attackers.
• Completely shut down by Taunt or phazing moves like Whirlwind.

Regigigas resides firmly in the ZU tier for Pokémon Scarlet and Violet, clinging to a microscopic 0.6% usage rate. This abysmal placement stems entirely from its notorious Slow Start ability.

While its raw base stats rival those of box-art legendaries, halving its Attack and Speed for five consecutive turns completely neuters its immediate threat level. In standard competitive play, giving your opponent five free turns is a guaranteed death sentence.

Consequently, its primary role is relegated to a highly niche physical attacker or stallbreaker. It relies entirely on surviving long enough to unlock its true stats, forcing players to build heavily around keeping it on the field rather than exerting immediate pressure.

To make Regigigas function in ZU, you must mitigate the agonizing five-turn wait. The most consistent approach utilizes Leftovers alongside stalling moves to waste turns safely.

• Item: Leftovers or Sitrus Berry
• Ability: Slow Start
• Moves: Protect / Substitute / Body Slam / Knock Off

Protect and Substitute are mandatory to burn through the Slow Start counter without taking lethal damage. You alternate these moves to safely run down the clock against slower opponents.

Once the five turns elapse, Body Slam becomes a devastating STAB option that also threatens paralysis on switch-ins. Knock Off provides crucial utility even while Attack is halved, crippling opposing walls by removing their Heavy-Duty Boots or Leftovers.

If you prefer to forgo the Protect/Substitute stall strategy, an Assault Vest set offers a completely different approach. This set focuses on pure longevity against special attackers.

• Item: Assault Vest
• Moves: Body Slam / Knock Off / Drain Punch / Earth Power (or Thunderbolt/Focus Blast)

Drain Punch is vital here, providing the only source of recovery while simultaneously chipping away at the opponent. The Assault Vest bolsters its already impressive Special Defense, allowing it to trade hits with special attackers effectively.

Interestingly, Regigigas possesses a surprisingly deep special movepool. Earth Power, Thunderbolt, and Focus Blast offer mixed attacking options that catch physically defensive walls off guard, as Slow Start only halves physical Attack.

Players looking for immediate, albeit highly risky, burst damage might experiment with a Choice Band or Weakness Policy. However, these sets require flawless prediction and heavy team support to succeed, often failing against competent opponents.

Regigigas shines brightest when positioned against passive walls that lack the offensive pressure to break its Substitute. If an opponent relies on status moves or weak attacks, Regigigas can comfortably sit on the field and count down its turns.

Once the ability deactivates, it instantly outspeeds and threatens a massive portion of the unboosted ZU metagame. Body Slam becomes a highly spammable move, punishing anything that attempts to switch in with heavy damage and a 30% paralysis chance.

It also performs well against teams heavily reliant on items. By utilizing Knock Off early in the match, it permanently weakens the opposing defensive core, making it easier for its teammates to clean up late-game.

Building a team around Regigigas requires partners capable of eliminating its hardest counters and providing safe entry. You cannot simply throw it onto a team and expect results.

• Dugtrio: Excellent for trapping and eliminating grounded threats that threaten Regigigas with its Arena Trap.
• Drifblim: Provides crucial support, potentially burning physical attackers to soften blows while Regigigas stalls.
• Muk: Acts as a specially defensive sponge, absorbing hits that Regigigas cannot afford to take during its vulnerable setup phase.

Clawitzer and Persian-Alola also serve as excellent pivots. Persian-Alola can disrupt opponents with fast utility and Parting Shot, while Clawitzer provides the immediate wallbreaking power that Regigigas severely lacks during its first five turns.

The weaknesses of Regigigas are glaring and easily exploitable. Fighting-type attackers are its absolute worst nightmare, easily blowing past its natural bulk with high-base-power STAB moves before Slow Start ever ends.

Beyond type disadvantages, Phazing moves like Roar or Whirlwind completely ruin its game plan. Because Slow Start resets every time Regigigas switches out, forcing it off the field erases all your stalling progress instantly.

Taunt is another fatal counter. By preventing the use of Protect and Substitute, Taunt users force Regigigas to attack with its halved stats, rendering it completely useless. If you see a dedicated Fighting-type or a fast Taunt user on the opposing team, leave Regigigas on the bench.

For standard in-game playthroughs of Scarlet and Violet, Regigigas is incredibly frustrating to use. Most wild encounters and trainer battles end in two or three turns, meaning you will literally never experience its full power.

Looking ahead to Pokémon Legends: Z-A (2025), players remain skeptical about its viability. In the previous Legends title (PLA), Slow Start remained a massive hindrance despite the drastically altered battle mechanics.

Unless Game Freak introduces a new mechanic or item specifically designed to bypass Slow Start, it will likely remain a bottom-tier choice. For a normal playthrough, you are much better off using Snorlax or Slaking, which offer immediate damage output without the agonizing five-turn wait.
