The events of Captain America: Brave New World could be devastating for an MCU hero introduced in Phase 4. Of all the Phase 5 installments released so far, Captain America: Brave New World may be the one that may have the biggest non-multiversal implications on the MCU’s Earth. The discovery of adamantium, an international war near-miss, Captain America’s decision to reassemble the Avengers, and President Ross’ destitution after transforming into Red Hulk in Captain America: Brave New World‘s ending are all events that will probably start significant chain reactions across the world.
