He is harsh and aggressive towards everyone he meets. He has a cocky, self-serving attitude. However, most of this personality is a front, as evidenced by the later seasons. He brings out the worst of all his teammates, usually forcing them to react by hitting them hard where it hurts. He uses peoples' pasts to annoy them to the point of rage when they are in his way and respects almost no one until later on in the story.
He has brown (and gray) hair in a mohawk and dark gray eyes. In the Aliea arc, he has a red lighting bolt scar on the left side of his forehead.
When he was a child, his father took the blame for his boss's failure and was forced to resign. His mother told him to become powerful. Caleb took his mother's words in a twisted sense and joined Ray Dark for power (which is all revealed by Hillman in season 3)
In season 2, he set up Royal Academy Redux in Ehime, and recruited David and Joseph to play a match against the Inazuma Caravan using forbidden moves like Emperor Penguin 1 and Beast Fang.
However, after they fail to beat them, Ray Dark abandoned him and Redux for not being good enough. He brandishes him nothing but a mediocre player, which demorlised him.
In season 3, Caleb was selected as a candidate to represent Japan in the FFI (Football Frontier International).
In the Asian preliminary finals he finally worked together with Jude and overcame their differences to beat Korea's team.
During the final tournament, Jude and David were thinking that Caleb was in contact with Ray Dark. In the next episode he, Jude, David and Mark helped Italy's natinal Orphes in their match with Team K.
In this episode, along with David and Jude, he creates the legendary Emperor Penguin 3 move to defeat Mr. D (Ray Dark) and show him how they don't need him anymore.
- Killer Slide : Caleb slide tackles the opponent head on with his legs moving extremely fast, too fast for the human eye to distinguish them and their positions.
- Breakthrough 2 : Caleb, much like Breakthrough 1, passes the ball onto the opponents chest, who, confused, doesn't pay attention to him jumping in to overcome them with a multitude of strong kicks to the chest, which stay legal thanks to him always aiming for the ball and nothing else. Finally, he leans back for a second then comes back strong with one last extremely powerful kick to the chest which propulses them back and onto the ground, while he controls the falling ball with one foot.
- Field of Force : Caleb runs towards Jude (who has the ball) and scissor kicks with great power the ball while Jude kicks it in the middle and does the same thing. This power turns into an explosion of purple light which forces the opponents onto the ground for some time.
- Emperor Penguin No#3: Jude, Caleb and David jump into the air. Jude then whistles out five purple penguins. The three of them rotates around the ball, levitate higher then smash the ball downwards to the goal with their ankles with the penguins following the ball for support.
