Cronicle is a soldier who will do as he is ordered, though he is noted of being critical of pilots who will bomb an area just to draw out a single renegade mobile suit. However, he is also a person who will not complain or criticize an order handed down from a superior officer to do the very same action. He is a man capable of ignoring the taunts of others about his failures. Cronicle has little interest in non-combatants and will order civilian children away from areas of danger.
He has an unusual habit of wearing a face-mask whenever he is piloting, but he does not wear it at other times.
Cronicle Asher is the younger sister of Maria Pia Armonia, the queen of the Zanscare Empire, making him the uncle to Maria's daughter Shakti. After Zanscare was formed, Cronicle rose through the ranks of Zanscare's military, obtaining the rank of Lieutenant and becoming Zanscare's flying ace.
He clashed with Uso Evin several times throughout the series, forming a rivalry with him that mirrored that of Amuro Ray and Char Aznable. He was later killed by Uso during the Battle of Angel Halo.
