Ashes fell down, from which Percival again regenerated. The ashes came together as if they were being mixed like cement, and a black blob appeared.
Two dark hands shot out of the thick and disgusting blob, then came the legs, but unlike the arms, they turned from a black fog to a white skin tone. (No the author is not trying to be a racist)
Gereon watched calmly as the enemy was regenerating. He hated this type of guy in the past, but now, they were his favorite toys. "Regeneration huh? Must have been a good life, not worrying about hospital fees." His eyes were gleaming with joy.
