Coalossal's Gigantamax form
Coalossal (Japanese: セキタンザン Sekitanzan) is a dual-type Rock/Fire Pokémon introduced in Generation VIII.
It evolves from Carkol starting at level 34. It is the final form of Rolycoly. It also has a Gigantamax form.
Coalossal is usually peaceful, but the vandalism of mines enrages it. Offenders will be incinerated with flames that reach 2,700 degrees Fahrenheit. While it's engaged in battle, Coalossal's mountain of coal will burn bright red, sending off sparks that scorch the surrounding area.
