Coalossal: Pokédex, Stats, Evolution, Abilities, Weaknesses & Moveset

Coalossal is a Rock- and Fire-type Pokémon introduced in Generation VIII. It evolves from Carkol at level 34, has a 510 base stat total, and is known for high physical Defense, entry-hazard utility, and the Speed-boosting Steam Engine Ability. 

At a Glance

Attribute	Detail
National Pokédex No.	839
Type	Rock / Fire
Generation	Generation VIII
Category	Coal Pokémon
Height	2.8 m
Weight	310.5 kg
Abilities	Steam Engine, Flame Body
Hidden Ability	Flash Fire
Evolution	Rolycoly → Carkol → Coalossal
Base Stat Total	510

Pokémon’s base stats are 110 HP, 80 Attack, 120 Defense, 80 Special Attack, 90 Special Defense, and 30 Speed. Its high physical bulk is useful, but its low Speed and major type weaknesses make positioning essential. 

Coalossal Evolution

Coalossal completes the Rolycoly evolution line:

• Rolycoly evolves into Carkol at level 18.
• Carkol evolves into Pokémon at level 34. 
• Pokémon Scarlet and Violet evolution guide

Carkol gains the Fire typing when it evolves from Rolycoly. Pokédex retains the Rock/Fire combination, gaining valuable resistances but severe Water- and Ground-type weaknesses.

Colossal Weaknesses and Resistances

Pokémon’s Rock/Fire typing creates a mixed defensive profile.

Damage multiplier	Types
4× weak	Water, Ground
2× weak	Fighting, Rock
1× neutral	Electric, Grass, Psychic, Ghost, Dragon, Dark, Steel
½× resistant	Normal, Ice, Poison, Flying, Bug, Fairy
¼× resistant	Fire

Because Water and Ground moves deal 4× damage, strong attacks of either type can threaten a one-hit knockout, even against the Pokédex’s high base 120 Defense. The actual outcome depends on the attacker’s stats, move power, Same-Type Attack Bonus (STAB), held items, Terastallization, and Pokémon’s training spread. 

Coalossal Abilities Explained

Steam Engine

Steam Engine raises Coalossal’s Speed by six stages after a Fire- or Water-type move hits it. This can transform a Pokémon with only 30 base Speed into an immediate threat, particularly in Double Battles where a teammate can activate the Ability deliberately. 

The risk is obvious: Water moves deal 4× damage. In the Sword and Shield era, Pokémon often relied on Dynamax, Weakness Policy, careful bulk investment, or redirection support to survive the activation and turn the Speed gain into momentum.

Flame Body

Flame Body gives Pokémon a 30% chance to burn a Pokémon that makes contact with it. This makes it useful against physical attackers and gives defensive sets a way to punish contact moves. 

Flash Fire

Flash Fire is Pokémon’s Hidden Ability. It grants immunity to Fire-type attacks and boosts the power of Coalossal’s Fire-type moves by 50% after activation. 

Is Pokédex Good?

Coalossal is a niche but useful Pokémon rather than a universally dominant competitive choice. Its high HP and Defense, access to Rapid Spin, Stealth Rock, Spikes, and Flame Body create real defensive value. Steam Engine is the Ability most closely associated with Pokémon’s historical doubles and VGC strategy.

However, Pokémon’s 4× Water and Ground weaknesses, low base 30 Speed, and limited recovery can make it inconsistent. In singles, it needs the right matchup and team support. In doubles, its Steam Engine strategy was most effective in formats where Dynamax helped it survive an activating hit, trigger Weakness Policy, and become immediately threatening. 

Colossal Competitive Moveset: Scarlet & Violet PU

In Scarlet and Violet singles play, Pokémon can operate as a niche defensive hazard setter and hazard remover. One current defensive approach uses the following framework:

Attribute	Choice
Ability	Flame Body
Item	Heavy-Duty Boots
Nature	Bold or Calm
EVs	252 HP with defensive investment based on team needs
Move 1	Rapid Spin
Move 2	Stealth Rock or Spikes
Move 3	Flamethrower
Move 4	Earth Power or Body Press

This is one practical defensive set, not the only viable Pokémon build. Its competitive movepool also includes options such as Earthquake, Fire Blast, and other utility moves, depending on the format and the rest of the team. 

Colossal Movesets

Scarlet & Violet Singles

For a support-focused singles team, Pokémon usually prioritizes utility:

• Rapid Spin for hazard removal and a Speed boost.
• Stealth Rock or Spikes for entry-hazard pressure.
• Flamethrower for consistent Fire-type damage.
• Earth Power or Body Press for coverage.
• Heavy-Duty Boots to reduce entry-hazard damage.
• Flame Body to punish physical contact. 
• Smogon Strategy Pokédex
  

Sword & Shield VGC

Pokédex’s best-known competitive role came in Sword and Shield VGC. Steam Engine and Weakness Policy enabled a high-risk, high-reward Dynamax strategy:

• Steam Engine
• Weakness Policy
• Heat Wave
• Meteor Beam
• Solar Beam
• Protect

A teammate could use Surf or another compatible Water-type move to trigger both Steam Engine and Weakness Policy. Steam Engine sharply raised Pokémon’s Speed, while Weakness Policy raised its Attack and Special Attack after it took super-effective damage. Dynamax increased Coalossal’s durability, allowing it to become a serious offensive threat in one turn. 

Wolfe Glick used Pokédex-based teams during the Sword and Shield VGC era, including the April International Challenge. He later won the Pokémon Players Cup II with a Pokémon-centered team, and a Coalossal based on his successful team was distributed to Sword and Shield players through Mystery Gift. 

Coalossal and Gigantamax

Coalossal has a Gigantamax form in Pokémon Sword and Shield. Gigantamax changes its appearance and gives it access to G-Max Volcalith, rather than the standard Rock-type Max Move. 

G-Max Volcalith damages opposing Pokémon over subsequent turns after the initial attack lands, making Gigantamax Pokédex especially valuable in the Sword and Shield VGC environment. Gigantamax mechanics are not available in Pokémon Scarlet and Violet, so this is now primarily a historical and format-specific part of Coalossal’s competitive identity.

Coalossal Availability by Game

Coalossal’s availability differs by title. In several games, evolving Carkol is the most reliable route; in others, Pokédex can also appear in the wild, Max Raid Battles, or Dynamax Adventures.

Pokémon Sword and Shield

Pokémon can appear in the Wild Area, including Dusty Bowl and Lake of Outrage, under specific weather conditions. It is also available in selected Max Raid Battles. In Pokémon Sword, Gigantamax-capable Coalossal could appear in certain raids, including at Giant’s Seat. 

The Crown Tundra

In the Crown Tundra expansion, Pokémon can be encountered through Dynamax Adventures. It can also appear in overworld locations, including Lakeside Cave and Ballimere Lake, depending on the version and weather. 

Pokémon Scarlet and Violet

In Pokémon Scarlet and Violet, the standard method is to evolve Carkol at level 34. Rolycoly is found in East Province (Area Three), northwest of Levincia and west of Zapapico, then evolves into Carkol at level 18. Pokémon is not generally found in the wild, although it may appear in five-star Tera Raid Battles. 

Games Without Coalossal

Pokédexis not available in Pokémon Brilliant Diamond and Shining Pearl or Pokémon Legends: Arceus. Availability can change with new titles, downloadable content, transfers through Pokémon HOME, and limited-time events, so always check the Pokédex for the specific game you are playing.
