From the information provided, it's clear that Jabbar, the middle-aged man, possesses substantial skill and strength. He's considered to be a practical fighter of the quasi-Red Robe level. His standing isn't a result of mere luck but a testament to his competence. However, a quasi-Red Robe is not quite a full-fledged Red Robe, and despite his substantial skill, his age made him less noticeable. Many assumed his success could be attributed mainly to his battlefield experiences.
In terms of choosing the Mecha model, Jabbar naturally opted for a high-performance model. Regardless of the opponent, as long as he didn't make mistakes during the battle, he believed victory wouldn't be too difficult.
But Sky Shadow was different; unexpectedly, he chose to enter the battle in a Federation main combat Mecha, a Beast.
