Old Man Phoenix is a version of Wolverine from Earth-14412, who becomes the Phoenix host at the end of the universe and joins Thor's daughters in the battle at the God Quarry. During the Avenger's long journey to save the Multiverse, they met many other Phoenixes, including the first human host, Firehair, who is Thor's 'mother' after breathing the Phoenix fire in him as a newborn.

However, in recent years, Marvel has made the Phoenix a stable part of the Avengers' lore and franchise, making its new host Maya Lopez, aka Echo.

The original host of the Phoenix in Marvel Comics was the X-Men's Jean Grey, and the Grey's bloodline still holds a special connection to the mysterious cosmic force. In the aftermath of the battle, both Echo and Logan seem to have lost their powers, and with Firehair dead the main hosts of the Phoenix Force are all gone. To give the rest of the team enough time to seal the breach, Old Man Phoenix, Echo, and Firehair have to use all the Phoenix Force at their disposal. In Avengers Assemble: Omega #1, by Jason Aaron, Aaron Kuder, Dexter Vines, Ivan Fiorelli, Javier Garròn, Jim Towe, and Alex Sinclair, Mephisto's destructive plan for the Multiverse unleashes the remnants of the First Firmament buried underneath the God Quarry, causing a massive flood that will destroy literally everything and everyone. To stop Mephisto's plan to destroy the Multiverse, several hosts of the Phoenix Force have to expend all their energy, which results in their complete depowering at the end of the story, hinting that the Marvel Universe no longer has a Phoenix. Warning: SPOILERS for Avengers Assemble: Omega #1Marvel Comics apparently gets rid of the Phoenix Force at the conclusion of the Avengers' long multiversal saga.
