Captain America's Evil 'Brother' Debuts New Codename as a Permanent Marvel Villain

Screen Rant

Uncanny Avengers #5 ends with the Unity Squad "defeating" evil Hydra Cap, revealing Grant escaped imprisonment and is Marvel's newest Flag-Smasher.

Captain America's Unity Squad defeats Evil Hydra Cap, but Grant Rogers emerges as Marvel's new Flag-Smasher, reinforcing the twisted state of Marvel's America.
Despite stopping Hydra Cap's terrorist plot, the corrupt American justice system allows Grant to go free, highlighting its failure.
Grant's new villainous persona as Flag-Smasher makes him even more dangerous, as he can spread his anti-mutant propaganda and serve as a figurehead for Orchis. The battle may be won, but the war against Orchis continues.
