Alhaitham

Alhaitham is a very fit (to put it lightly) man who can constantly be found wearing headphones and reading a book. He's got gray hair that whitens at the ends, with some light turquoise undertones on patches. His eyes are also light turqoise, with the area around pupil an autumn orange.

In terms of physical combat, he's a very capable single and dual-sword fighter, in a style that utilizes a lot of spins and turns while focusing on efficiency. A preview of his combo can be seen here.

He's a man who puts a much heavier emphasis on mental exercises over physical, so anyone attempting to peek in on his mind will find it running in several different directions, constantly considering numerous factors. He's exceedingly rational and logical in almost every interaction, while pursuing a comfortable and laidback lifestyle, which leads to a very interesting, albeit probably infuriating, person.

Alhaitham carries a Dendro vision, Dendro in Genshin-world typically means plant-based powers. For Alhaitham specifically, he manifests his in combat in the form of chisel light mirrors and 'light' projection/manipulation, using them to be able to 'teleport' within a certain range, manifest a second sword to use with his primary one, and inflict additional attacks alongside his physical ones via light-generated projections. He is also able to generate an area in which he can refract light projections to deal damage for a brief period of time. A general visual overview can be seen here
