Overview
Jackson Jekyll is a 2010-introduced character, part human and part fire elemental, with an alter ego named Holt Hyde.
Jackson Jekyll is a 2010-introduced and all-around character. He is the great grandson of Dr. Henry Jekyll. He is part Humans and part fire elemental, as his father is one. Due to his mother's Jekyll/Hyde lineage, he has a monstrous alter ego named Holt Hyde (G1). Jackson longed to be a monster until he discovered his alter-ego whom he now wars with. Believing himself to be fully human most of his life, he has grown up among monsters in a world where the two groups mutually dislike each other, probably causing him to be cautious and shy but not easily intimidated just because someone's a monster. As well as careful and kind, Jackson is a dedicated scientist and one of the best students at Monster High (G1).
