Sir Theodore III

Sir Theodore III is a fictional character/alternate persona created by KSI for the Sidemen Bake Off and Sidemen Dragons Den videos. Given that JJ plays him, they obviously both look identical. However, Sir Theodore III has noticeable black Afro hair, wears glasses and speaks in a posher accent compared to his counterpart.

Description
Sir Theodore III has a large vocabulary, as seen in the Sidemen Bake Off intro, where he used words like baroque, boondoggle, fastidious and sycophant. However, he later admits that he does not know what these words mean, although they do share a relation with the content of the video in general.

He also appears to be very insensitive towards middle/lower class citizens and those in need, as he expressed disgust in the Sidemen Bake Off video when he realised the Sidemen took public transport and requested for them to change their clothes, saying that one of them might have touched a 'commoner'. In the Dragons Den video, he also mentioned in a pitch by Callux and Calfreezy that none of the profit of their sales go towards charity, and would like to support cancer.

During the both videos he featured in, he is shown to be short tempered. He pushed a table out of rage numerous times throughout the Dragons Den video when his outlandish investment pitch was denied. He also lost his temper easily at most members of the Sidemen throughout the Bake Off when they would become distracted from cooking.

Theories & Speculation
According to the Sidemen Bake Off video, he mentioned that he was knighted by Queen Elizabeth the 500th, and strongly shows that he is from the future. Besides that, he has also repeatedly mentioned his hatred for children. When countered by Zerkaa, saying that he was a child once, he replied stating that he was never a child and was born a man. He might be literally saying that as in the future, technology may be so advanced that the process of childhood is skipped.
