Seeking to prove his strength against strong opponents, he never stops looking for a challenge However, he has also shown care and respect to others at times respect Zoro skill as swordsmen Luffy his Captain and Hayate

Saizo likes to train constantly, and when he's not sparring, he's working out. For him, physical conditioning is almost an obsession. Saizo believes in strength and power, and that one must feel the power within oneself. He respects other individuals who display their own confidence and strength.

Many times, he has suffered injuries which would kill a normal person and muscled through them through sheer willpower, such as when he was given his gaping scar, which he allowed to be inflicted on himself deliberately, and when he absorbed all of Hayate's pain from his fight with Gekko Moriah after Bartholomew Kuma pushed it out of him and made Saizo take it upon himself in return for sparing his Vice captain's life, which was so traumatic that his eyes temporarily became bloodshot. As a result, he has often been left very heavily bloodied and bandaged, as well as gained scars more times than anyone else in the Straw Hat Pirates crew other then Zoro, all of which were notably inflicted after joining Luffy on his travels. Despite this, he has a habit of ignoring these dire injuries and continuing to fight, sometimes before he is fully healed like Zoro.

Saizo tends to face death in a defiant manner and show no fear of dying even when he is in a gravely injured state.
