What's sad is eggman probably has a post mortem plan... So there goes even more trauma for both Metal and Sonic not only it is possible that eggman has it IT IS CERTAIN remember Archie when the first robotnik died a new one from another dimension came out of nowhere or probably there are robo eggmans or just he has a way to revive himself it is so impossible to manage to kill him forever that literally the whole future of Sonic has shit happening because of eggmans legacy... It is so sad and yet it reafirms how evil and egocentric eggman is... So much that he will never truly die until he feels like it
