Holt Hyde

Holt Hyde is a character from the Monster High franchise.

Due to his mother being of the Jekyll/Hyde lineage, he has a human alter ego by the name of Jackson Jekyll. Holt himself is a mixture of the Hyde-condition and a fire elemental, making him much more willing to break the rules and shirk responsibilities than his counterpart named Jackson. He and Jackson do not get along very well because of this, but they do care for each other. Holt is an enthusiastic and popular DJ around New Salem and is often asked to take care of the music when his fellow students have another party. In the books, his name is D.J. Hyde.

In the AWA fics, Holt is a student at the AWA Academy.

Appearance
Holt has blue skin, sunrise-like eyes and a black symbol on his face. It's most likely a tattoo, however if it was, then Jackson would probably likely have the tattoo as well. His hair is made of flames and he has a yin-yang tattoo between his shoulders where Jackson has the tattoo on his back. He has an eyebrow piercing on his left eyebrow, which Jackson shares.

Personality
Holt is a DJ, so he's very social and into promoting his music. He admits that he is "hot-headed" and can have a bit of a temper. However, when it comes to his music, Holt has access to a quiet side in favor of the creative process. He enjoys to spend time at a small, secluded spot near Epic Falls during those periods. Holt Secret Hyde-a-Way His choice in clothing style is a black-and-white shirt may be a reference to his split personality alter ego side of Jackson.

Abilities
Throughout each storyline, Holt and Jackson have no control over their transformations and change from one into the other under specific circumstances. In the cartoon series, it seems to be music that causes Holt/Jackson's transformation. This is first seen in "Hyde and Shriek".

In his ' Basic ' diary, Holt's transformation into Jackson Jekyll normally occurs at sunrise and lasts until sunset. Holt noted that when he was trying to see what the town was like during the day, he blacked out at the moment of sunrise. However, in Jackson Jekyll's 'Between Classes ' diary, it's revealed that the trigger for Jackson's transformation has since changed, so that it is now also music as in the cartoon. Specifically, "music with a 4/4 time signature played in excess of 90 decibels" triggers the transformation into Holt. However, according to the diary, because of Jackson's "elemental heritage + Hyde transformation + teenage boy" status, it is likely to change again at least once more before he hits adulthood.

In Holt's 'Basic ' diary, he displayed one example of having some elemental powers from Jackson's parental heritage, as he melted the pen he was using and his entry indicated this had happened before. His bio also uses several fire related puns.

In the Monster High book series, the change is caused by temperature shifts, be it from him getting hot from embarrassment or from outside forces like a hot day.

There are times when Jackson's and Holt's memories and abilities leak over to the other. For example, in the diaries, Jackson is able to keep up with Deuce Gorgon in a basketball game (to Deuce Gorgon's surprise), while Holt recognizes Draculaura at a club despite the fact it's the "first" time he meets her.
