Stoneheart

Stoneheart (voiced by Matt Mercer) is a rock golem supervillain. Stoneheart is a huge, muscular gray rock golem with glowing yellow-green eyes. As Stoneheart, he is extremely aggressive and furious, his enemies, including Kim and Chloé, being the ones he is the most furious at. He still loves Mylène, but his reasoning has been clouded when it comes to her and he believes that Hawk Moth will bring the two to be together forever.

Powers and Abilities
Stoneheart is a golem endowed with superhuman strength. He has a strong grip with his hands, being able to securely hold human victims or the wad of paper that is the akumatized object. Although not very fast when running, he still has fast enough reflexes to grab things in mid-air, and can throw things, like a human or vehicle, with a lot of power. Additionally, when he gets hit with an attack, he grows in size and his strength increases.

Due to Ladybug not purifying the akuma, the akuma multiplies and transforms civilians into frozen versions of Stoneheart. When Ivan becomes Stoneheart again, the copies of Stoneheart begin to move, and they are under the original Stoneheart's control.
