Nikola Tesla is a rather tall, young and lean man with curly brown hair that's parted at the front. He wears a formal wear with a white shirt, black tie and waistcoat. He also wears white pants with a pair of boots along with a long jacket, where the bottom left side is made out of a black netted material. A feather is pinned to his left lapel and he wears a glove on only his right hand. Both hands have two rings on each finger. Tesla also wears a pair of goggles that usually hang around his neck. These goggles and his hairstyle seem to be inspired by his older brother, Dane Tesla, who he looked up to. Tesla is a man of science, who deeply loves his work and the laws of physics. Because of this, he refuses to let someone compare it to magic.[1] His passion for science can sometimes make him behave in an insensitive or rude manner, as seen when he started touching and staring at Göndul to see if she was a "material" capable of making his theory into a reality.[2] Nikola explains that it is by mistake that humanity evolves Nikola Tesla believes that Humanity is able to evolve through failures According to Marie Curie, Tesla is a man who is very obsessed with his research[3] and as a result, this trait can lead to Tesla having a tendency of forgetting about everything else and only focusing on what interests him. For example, after Beelzebub overpowered him in the early stages of the eighth round, Tesla, despite being injured, got excited over how the Staff of Apomyius increased the energy of his opponent's vibrations. He even asked Beelzebub to let him borrow the staff so that he could study how it worked.[4] Due to his love of science, Tesla is also severely intrigued by anything that could allow Humans to advance, and is especially proud of them when he figures them out. This love of advancement even went as far as him explaining the exact strengths and weaknesses of his teleportation ability, one of the few advantages he had over Beelzebub, right in the middle of their fight. His pride in advancement stayed with him to the end, using his last moments to deliver a speech to the rest of Humanity, claiming that, so long as advancement continued, Humanity would live forever.
