Holt Hyde is a Monster High doll, released in 2010. He has an alter ego (as another doll), this doll represents the mixture of a hyde-condition and fire element. As a doll, he has flame hair, blue skin, and is currently wearing a black and white two-toned t-shirt and purple striped pants. 

I remember getting this doll on Christmas nearly 14 years ago, and it is one of our oldest Monster High Dolls next to Deuce. I just remember myself being really enamored of the texture of his flame-haired hair, the way the paint is painted on the clear plastic; I had never seen anything like it. This doll has been through it, literally having threads of hair stuck to the doll that are nearly impossible to remove.
