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".
She was attacked by the pack of dogs along with Swiftpaw, who was killed. They went after the pack because Bluestar had not given them their rightfully earned warrior names due to the fact Tigerclaw was a traitor. Bluestar thought everyone in her clan was a traitor because of tigerstar and so swiftpaw and brightpaw went after the dogs and brightpaw was able to climb a tree(i think,i can't remember) but swiftpaw was dragged out of the tree he was trying to climb to get away from the huge dogs so he died.
