She has switched codenames several times to help out another troubled hero. She’s also transformed into a few new costumed identities due to the Marvel universe’s frequently shifting reality. Rambeau is one of Marvel’s most powerful heroes, but she hasn’t had much luck with her various alter egos.
Rambeau was hoping for a fresh start after her time with Nextwave, so she rebranded herself with a new name and an updated costume. She took on the identity of Spectrum with a sleek black and white costume that referenced her former Captain Marvel look. She joined Luke Cage as the leader of the Mighty Avengers when she made her debut as Spectrum.
Her Spectrum identity also referenced her abilities, and she excelled in the role. She joined the powerful team of Ultimates alongside heroes like Captain Marvel, Blue Marvel and Black Panther. She began wearing her Nextwave trenchcoat over her Spectrum costume, though she also added Blue Marvel's vest to the costume when she joined the latest roster of the Thunderbolts.
