@Super-Community SUPER-SPEED! Because If you have super-speed, you're crossing out like what… 5 different powers?!
First off, superspeed automatically means you can be invisible by vibrating at the speed of light- and outpaces the universe’s speed limit- light… allowing a different kind of superpower to be an option: time travel! This automatically translates to the tampering of time and space.
Additionally, the ability to match the frequency of any universe in the multiverse can- by definition- let you weld the power of multiverse jumping. Not only that but since time is relative you can basically freeze time by surpassing its speed and you can create sonic booms by exceeding the speed of sound- so you are a living F-15 military jet moving at March 7 speeds- which also makes superspeed cross out high-powered sonic screams as a power cuz I would think a sonic boom could do the same?
A sonic boom could shatter objects and incapacitate and even kill powerful foes. Let’s not forget that with superspeed you don't need teleportation cuz- come on, that’s self-explanatory, you faster than light! So it’s like a six-for-one deal.
So if being the next Barry Allen or Sonic the Hedgehog does all that, then BOOYAH!
