Phox was born to Peregrine (deceased before his birth) and Fox (deceased immediately after his birth) Redhawk and raised in Redhawk Caldera by his older sister, Raven. There is also some ambiguity around who his father is, seeing as though Fox was screwing Kaizer at the time, too. Phox was incredibly close to his deaf sister, Towhee, growing up. When it came time to go to war with another pack, he fled, unable to fight or deal with the fact that he might have to watch some of his family die.

He returned to the Teekon Wilds at the end of October 2018 on the brink of death. He was graciously allowed by Towhee to return to the Redhawk clan, but he was instructed that he would need to earn the right to use that name again.

After a couple of months of healing and proving himself (mainly to Towhee), Phox regained the right to call himself a Redhawk. During this time, he also found a very frightened Camilla and vowed to keep her safe from her previous imprisoners. Unfortunately, she was captured not long after, and Phox went after her. He found her, but her captor knocked him unconscious... but not before he tore a nice chunk into Phox's face. He and Camilla were eventually reunited right around the time his sister, Wildfire, formed the Firebirds pack nearby.

Camilla continued to call Phox her "husband," and eventually Phox relented and the two became mates. Not too long after, they conceived their first litter. Fig and Fennec came into the world, and Camilla died a few weeks later due to complications.

Once Fig and Fennec were a couple of months old, Phox, Towhee, and the two children left the Redhawks to start Asterism Grove. This was for a variety of reasons, including not feeling welcomed by Quixote, wanting a safer place for blind Fennec, and Towhee's fight with Tegan. Their claim was solidified in early July with both Phox and Towhee taking lead of the pack.

After tumbling down a landslide caused by earthquakes in the early fall, Phox was left with serious injuries, including going blind in his left eye. He was still cut-off from the rest of the pack, including Towhee. Unable to resume his duties, he went to live with Raven as she nursed him back to health. He was accompanied by his son, Figment, who received mentorship from Rannoch.

As soon as Phox was able to travel, he returned to the Teekon Wilds, correctly assuming that Towhee had joined the Firebirds. The surprise was that Fennec was there as well, and so the little family of four was once again whole. Shortly after his arrival, he reconnected with and expressed his long-held attraction to her. After some ups and downs and a couple months of uncertainty, Phox and decided to make things official and become mates.

Around the time was beginning to show the first visible signs of pregnancy, Towhee gave birth to a surprise(!) baby, whom she named Meerkat. Phox was immediately crowned the father, in every way except biologically. A month later, gave birth to three children: Primrose, Alyx, and Quetzal. Fennec abruptly left the Firebirds with Penn not too long after, though Phox did his best not to be too angry with her sudden departure.

Fennec returned some time later, along with Penn, though the latter did not end up remaining with the Firebirds. A flood forced them from the copse, though they were able to return not too long after. Alyx was lost during this time, and Phox thought the worst. Eventually, they moved back to Redhawk Caldera, and Alyx was reunited with them. Meerkat, Fennec, and Bronco went to live with sister packs (Moonspear and Firefly Glen). Alyx grumped about this, wanting to get away from family.

In the fall and winter, many things happened in rapid succession. Fennec went missing, hurt herself badly, but eventually returned to Redhawk Caldera. Phox and Figment went to gather some of her belongings that she'd left behind, and while they were gone, Alyx was attacked and Primrose passed away. Despite this, Phox tried to remain a rock-like figure for Niamh and the children.

Though the timing was unwelcome, and they were still grieving the loss of Primrose, Phox and Niamh conceived their second litter together. Around the same time, Towhee and Reyes conceived a litter as well. Things felt like they were getting back to normal, until Reyes and Niamh got in a spat, and Reyes broke Niamh's leg. With no other option, Phox chased Reyes out of the pack.

Unbeknownst to him at the time, Towhee had a partial miscarriage, losing two of her puppies. Niamh began to stew over Towhee not visiting her, resulting in her growing more and more angry until she told Phox she planned to usurp the Sovereign. Phox, unwilling to pick sides, flipped a piece of bark instead to decide. Niamh grew even more angry, eventually fleeing the caldera while Phox experienced one of his worst migraines yet.

He searched a month for Niamh's whereabouts, and after his only tip was in Yuèlóng, he decided to stay there and wait for her return. Another two months went by, and eventually the pack dissolved. Thinking his best bet was to follow the wolves who Niamh had last been seen with, he migrated once again, this time to Blacktail Deer Plateau. In late June, two of Mou and Maegi's children (Peregrine and Prevost) disappeared. Meerkat was reunited with her father, and it was only then that the parents revealed the children were Phox and Niamh's (and that Niamh had died on the day they were born).

Phox eventually ended up with Towhee in Mereo, where he spent much of his time perfecting his fighting techniques. In late 2022, after Towhee moved to Epoch, Phox went to spend some time there, but never made it. After getting side-tracked, and while crossing a road, he was hit by a car and taken into the care of humans. His left leg was crushed and surgically removed, but he was deemed well enough to return to the wild after he had recovered. His own memory of these events is hazy at best.

The following spring was spent going on several failed dates, although some had seemed promising from time to time. Phox even toyed with the idea of helping Fennec and his grandson, Killdeer, establish a new pack, but that plan was waylaid when Maxim went missing, not long after the birth of Towhee's two daughters: Sable and Towhee Jr. Phox stepped easily into the role of father for his two niblings, doing what Towhee had done for him years ago with Figment and Fennec.
