So you believe Flashes punches are light?
Let's throw the IMP away and assume that he gains no mass.
Let's just assume that the only kinetic energy experienced from the punch is from the normal mass of flash's fist/forearm and the speed of the punch.
So if Flash hits someone at 299,792,457m/s (less than the speed of light) while his fist and forearm has a normal 2kg mass. The kinetic energy is more than 21 million tons of TNT. This is more than several times many nuclear weapons.
So if a character failed to be KOed or killed from such a punch then it's a durability feat for them. That means 21 mega tons of TNT is cotton candy for them. It's on you to prove that's it's cotton candy for Hulk, Thor, etc.
Adding in the IMP calculations (more mass) then Flash is hitting with over 260 million tons of TNT per punch.
