Ace of Hearts in What is pain, Papa? (Patreon)

Sam Harrison is Adamant's biological son by "Goldie" Harrnacker, so he is extremely hard to hurt. To the point where he's unclear on what pain is. But his strength isn't as extreme as Ace's, which is probably a blessing.

Adamant's jet-black hair combined with Goldie's bright blonde mane to make red hair, which pleases Ace greatly. Gives him a nice, if irrational feeling that there's a little something of him in his son's looks.
