10 Characters That Could Make Up MCU's Young Avengers
7. Speed
Tommy Maximoff is currently in the same situation as his older brother Billy, in that he technically doesn't currently exist in the MCU as we know it. He disappeared when Wanda brought the Hex down, but it would appear that there could be some other universe from which he can be reached.
With Doctor Strange and Tommy's mother set to play around with the Multiverse of Madness in 2022, there is no reason to believe he won't be back in the near future.
Speed, whose powers are reminiscent of those of his Uncle Pietro's, wasn't a founding member of the Young Avengers in the comics like his brother. Instead, he was recruited from prison to help the team rescue Hulkling, before ultimately finding out that he and Billy were long lost brothers.
This likely won't translate to the MCU, as they have already grown up (kind of) together. Instead Tommy will come to the Young Avengers as a pair with his brother, regardless of whether they help initially form the team or not. This will give Speed the opportunity to properly use his powers, rather than just acting as a transport system for Wiccan as he did several times in WandaVision.
