Tortunator

Sun: The shell on its back is chemically unstable and explodes violently if struck. The hole in its stomach is its weak point.

Moon: It gushes fire and poisonous gases from its nostrils. Its dung is an explosive substance and can be put to various uses.

Ultra Sun: It lives in volcanoes and eats sulfur and other minerals. Materials from the food it eats form the basis of its explosive shell.

Ultra Moon: Its exploding shell poses a real danger but is sensitive to moisture. On rainy days, Turtonator takes silent refuge in caves.

Sword: Explosive substances coat the shell on its back. Enemies that dare attack it will be blown away by an immense detonation.

Shield: Eating sulfur in its volcanic habitat is what causes explosive compounds to develop in its shell. Its droppings are also dangerously explosive.
