What you are asking is "what causes sonic booms?"
They are caused by pressure waves from an object traveling through air. When these waves reach the speed of sound the energy released is in the form of an "explosion".
super sonic with bombs and he throws bombs every where and you bump into everyone
Meteor impact, volcanism, bombs.
It occurs when Sonic is in his super form and is extremely stressed. The exposure of chaos energy in his body along with the feeling of anxiety causes him to become Fleetway Sonic✨
Yes, it is the transition from subsonic to supersonic and then back that causes the sound.
For Sonic you have to deflect the bombs back at Eggman, for Blaze you have to throw fireballs at Eggman Nega. Both of them will have simultaneous turns when fighting both Eggmans,you will probably have to do it six times.
Guns bombs anything that causes pain really
Below I have added some links about some unconventional bombs that were used during World War 1. Bombs basically have chemicals/powders that ignite when the bomb lands or a detonator causes the bomb to explode. You will be amazed at what bombs were around then when you see the links.
An aircraft traveling at super sonic speeds will crease pressure waves or shocks that send off huge explosions.
Ash, cinder and bombs erupt explosively to form a cone shaped hill
That's a sonic boom. Sound waves are never supersonic in themselves, objects can be supersonic ... which causes a pressure wave (which moves at "sonic" speeds) and which can be heard (firing a gun will do it).
Either get a weapon made out of the khezu materials and use sonic bombs to stun him then hit him in the head(sonic bombs only work when he is under water) or bring some bowgun and us thunder S rounds and every possible round until he dies(this takes a while so don't get frustrated).
Radiation will always harm people no matter where they are, as it causes cancer.
