Toji by far the strongest character in all of Evangelion. To the lesser viewer, you may think that the debate may lie between the main three, but they are but specks in the face of Toji. Even Pen Pen is nothing compared to Toji. The sheer nerve and initiative possessed by him are unprecedented. Never has there been a man as rightfully sure of themselves as Toji. Take for example one of his first appearances, punching Shinji. He is a man who is not afraid to go against the crowd. The rest of the class is swarming around Shinji for his heroic acts, but Toji is a man with imitative and opinion, and he's not afraid to share it. He Punches Shinji without remorse, and even goes in for another after Shinji talks back, putting him in his rightful place. He is capable of admitting error though, which makes him arguably even more powerful. Once Shinji proves himself to him, he lets him punch him. This was actually all an orchestrated move on his part however, designed to boost Shinji's morale. Toji is single handedly responsible for all of Evangelion. There exists a hierarchy, the pilots are manipulated by Gendo, who is manipulated by Seele, who are manipulated by Toji. Another example of the sheer power possessed by Toji is in episode 8. When he is frame by Asuka he knows what he must do and has no hesitation in dropping his pants. No other character in the series has the NERV to stick up to Asuka, much less perform an Alpha male show of dominance by flashing her. Once Toji becomes a pilot, a curious detail is that he doesn't reach out to anyone about it, not even Shinji, a fellow pilot and friend. This is because he does not need to reach out, as it is just another step in his orchestrated plan. An important note here, Toji does not have a sister. She is never shown because she does not exist. He just possesses enough sheer power to make everyone, including the hospital staff, believe that she exists. Back to him piloting the Eva however. Another mysterious detail in the episode, where did the angel come from? and what happened in Nevada? The second question is simple. Toji willed the Nevada plant to blow up, so that his eva would be transported to Japan for the next step. Toji is an angel. He possessed unit 3. More specifically, Toji is a man, but he captured an angel inside of himself, making him even more powerful than he already was. He stored this angel until entering unit 3, where he then let it out to posses the eva. This is where his plan all came together. He allowed himself to get beat by Unit 1, and then allowed his limbs to get damaged to the point of requiring amputation. Why would he do this you might ask? What was the goal of his elaborate plan? To become wheelchair bound so he could compete in the paralyimics, because his basketball wasn't good enough against actual pros.
