Obtainable in Sword/Shield, I would have to say Coalossal. It has 110 HP, 120 Defense and 90 Special Defense. Also, it has access to moves like Will-o-Wisp, Iron Defense, Smokescreen and Rest for extra bulk. Also, it has access to attacking moves like Flamethrower, Earthquake and Rock Slide. Also, it can learn Burn Up to lose that 4x water and Ground Weakness.
