Something that appears in the movie. He gets blasted by a missile while he was in perception, for context.
Sonic: 116 px/1 meter (Given using his game height seems inconsistent, as he looks much shorter, like his classic counterpart)
Explosion: 936 px/8.06896551724 meters (radius is 0.00403448275862 kilometers)
((0.00403448275862/0.28)^3)/1000 is 2.99150338e-9 megatons/12.51645014192 megajoules, or Wall level+.
But this isnt nuclear, so we divide by 2. That is 6.25822507096 megajoules, or Wall level.
Huh, neat.
