My take on “New Yoke Sonic”
His legs got transformed in robot legs but managed to escape the transformation chamber. Both Amy and Sonic escaped but was cornered after Sonic learned his new legs can’t handle the force of his speed. Amy later sacrificed herself to allow Sonic to escape.
Sonic later took in Nine but is over protective bc of Nines involvement with the Rebellion. Sonic fears the Eggmen because of what they did to him and Amy. Sonic doesn’t want the same to happen to Nine.
New Yoke Sonic learns how to be brave again without his speed. Though it is his identity, it does not define him as a hero.
