A cinematic portrait of a superhero standing on a rooftop at night

A cinematic portrait of a superhero standing on a rooftop at night. Combine the classic look of Captain America with the chaotic energy of Deadpool. The character should have a determined expression, wearing a tattered American flag costume with cybernetic enhancements. They should be holding a vibranium shield in one hand and a pair of glowing katanas in the other. The background should be a rainy cityscape with neon signs.
