Beak

Beak and Angel were given a cabin in the woods next to the mansion to live in with their kids.

Later on, all of the students from the special class joined Xorn's new Brotherhood of Mutants, and Beak also joined the Brotherhood but he soon rebelled against them.

After some time the reality-hopping team known as the Exiles came to Earth-616 and Beak helped them on a mission, after which the Exiles were forced by the Timebroker to trade team-member Nocturne for Beak against his will. He had no choice and went with them and was crucial in the defeat of both Tanaraq and King Hyperion.

Many missions later he was returned to his reality just in time for the Scarlet Witch's de-powering of mutants resulting in Beak, Angel Salvadore and five of their six children being de-powered. Beak, however, was just happy to be reunited with his family and returned to live in the hut near Xavier Mansion.

One of Beak and Angels kids, Tito Bohusk, still has the mutant gene.

New Warriors

Sometime after that, Beak, along with Angel Salvadore, joined the newest incarnation of the New Warriors under the new code-name Blackwing. He also now calls himself Barry. Still de-powered he now has a costume that allows flight. Apparently he has worked out and got a nose-job. He also recruited depowered New Mutant Renascence to join the new New Warriors. Beak and Angel and their kids now lives in a big house.
