BlueFire

BlueFire is the het ship between Fireheart/star and Bluestar from the Warriors fandom.

Canon
During Into The Wild, a ThunderClan patrol finds a curious kittypet named Rusty, and they allow him to join the clan.

Bluestar introduces him to the rest of the clan, naming him Firepaw, and taking him as her apprentice, teaching him how to become a good warrior.

Eventually, a few books later, he gets his warrior name, Fireheart.

Then, when the deputy, Whitestorm dies, Bluestar names Fireheart her new deputy.

When Bluestar becomes sick, Fireheart is very worried for his leader, and is checking on her often. When she is too sick to go to gatherings, Fireheart filled in a few times before Bluestar was better again.

When RiverClan invades Sunningrocks, Bluestar gets attacked by Mistyfoot and Stonefur, who Fireheart know are Bluestar's kits. He stops the attacking by revealing this.

Then, Bluestarsacrifices herself to save Fireheart from a pack of dogs, falling into the gorge, and into a river. They manage to fish her out, but it was too late, and Bluestar slowly dies.

When Firestar is getting his last life, he gets it from Bluestar, who gave him the life for nobility, certainty, and faith.

Fanon
BlueFire is an unpopular ship within the Warriors fandom, barely getting any fanart and fanfics. Those that are out there may be hard to find due to the unpopularity of the ship.
