He has a tattoo on his left shoulder that consists of a winged heart and a snake, with a ribbon that reads 'Amore e Morte' ("love and death" in Italian) and has a very big mouth.

[5] Chad is a quiet person with a very kind heart and is sometimes the subject of jokes or bullies because he never fights back, against ordinary humans, or often hollows and Soul Reapers until necessary.

After his encounter with the cockateel containing the soul of Yūichi Shibata, he starts to detect the approximate locations of spirits and hollows, but cannot fully see them.

This also awakens what Chad later learns to be his latent powers as a Fullbringer, a human who manipulates the soul of an object to its full potential as the result of absorbing residual spirit pressure from a Hollow while unborn.

[6][9] Chad's armor increases his strength beyond its already impressive level, and enables him to fire powerful energy blasts from his fist.

Not too long afterwards, Chad accompanies his friends (sans Uryu) to Hueco Mundo in order to save the Arrancars from the Wandenreich.

When Ichigo departs to assist the Soul Society against the Wandenreich invasion, Chad, Orihime and Urahara are grievously injured by Quilge Opie and fall to his arrows.

[32] Carlo Santos from Anime News Network (ANN) agreed on this although he found his visual design to be stereotypical, but his personality was unique.

[33] Jarred Pine from Mania Entertainment found Chad's reveal of spiritual powers as his favourite from volume 5 of the manga, additionally noting that it does not drag out the story.
