So, the government makes an oops. They try to create a superpowered special forces, but instead they create a group of five insane terrorist with
Near invulnerability/only heavy artillery and nukes can take them out
The 5 go on a rampage in many major cities, and the military is getting their Gluteus Maximus’s kicked trying to stop them. Their is one person, Bryan, who they think can do the job. All he has to do is inject 5 specially made needles into the Metahumans, and it will give them seizures so powerful, they will be in comas, forever. But, he has to be close up to inject them, and if he does it to one, the others will kill him. He needs to be able to match their powers, but injecting him would make him insane to.
So: How could Bryan possibly match the powers of the Metahumans
