When Firestar became leader of ThunderClan he renamed Lostface (Brightpaw) Brightheart
Her name is Brightheart (Brightpaw when she was hurt by the dog pack).
It depends. If you mean someone to have their warrior name changed, then it's Brightheart. But the first apprentice to be made a warrior by firestar is actually Thornclaw.
No, Lostface and Brightheart are not the same cat. Lostface was a former ThunderClan cat who suffered a disfiguring injury and later joined ShadowClan as a warrior named Brightflower. Brightheart is a current ThunderClan cat who also faced a serious injury but remained in ThunderClan and is known for her resilience and courage.
Brightpaw's face was badly scared by a pack of dogs, and Bluestar, believing that Starclan had abandoned her, gave Brightpaw the name of Lostface to show what Starclan was doing to her clan.When Bluestar later regained her faith and Firestar became leader of Thunderclan, he changed Lostface's name to Brightheart.
The name Marchella can be traced all the way back to the Ancient Roman god of war, Mars. His name means "warrior, fighter"; therefore Marchella means "warrior, fighter".
