The Serious Man
Captain Chronos actually hesitated in recruiting The Serious Man, because his world's end was very dangerous even to Chronos. His world was literally dissolving into nothingness, his entire universe ceasing to be. But nevertheless, the good Captain felt it was the only way.
The Serious Man's powers are subtle. Everything around him becomes, for lack of a better term, a little more real. Powers that warp the laws of physics stop being able to do so. Chemistry starts working on very hard and strict laws. Energy beams can exist, but if you want to bounce a shot - well, better make sure that mirror is pretty much optically perfect.
Why was this important? Because he was up against a force that was making everything UNreal. making it fake, false, a creation of a diseased mind. The universe cannot hold itself together without effective constants, and now there were no constants. For years earlier, a strange and warped mind had discovered a way to impose his worldview on the entire universe. Now, The Serious Man must find and stop that crazed individual.
He must stop Foxbat.
