Monica Rambeau's New Powers Explained

Even though WandaVision takes place in the Marvel Cinematic Universe, the show draws much inspiration from the comic source material, perhaps even more so than the movies. For example, Wanda's children Billy and Tommy (Julian Hilliard and Jett Klyne) have developed the superpowers of their comic counterparts' reincarnations. Likewise, Monica Rambeau's new powers are ripped straight from the pages of Marvel comics.

In the mainline Marvel continuity, Rambeau goes by the nom de guerre of Spectrum, which is on the nose, given her powerset. Basically, she can transform herself into and use virtually any form of energy within the electromagnetic spectrum. These include X-rays, gamma rays, infrared and ultraviolet radiation, and, of course, electricity. Rambeau/Spectrum has standard abilities such as flight and superspeed, but she can also phase through objects, become invisible, and blast opponents with the energy she currently exhibits. After all, it's not like you can see or feel X-rays. And yes, Rambeau/Spectrum can pick up on things humans can't, such as changes in the electromagnetic spectrum.

While the Marvel Cinematic Universe's Monica Rambeau hasn't phased through objects yet or blasted Wanda with electricity, she might get there eventually. But will the powers develop naturally, or will they require a few more trips through the Hex? We will have to wait and see.
