Sonic dodges Goku's attack and strikes him, leading to a back-and-forth exchange where Goku struggles to land hits. Sonic uses a spin dash attack, but Goku counters, resulting in a massive explosion. Goku's Kamehameha nearly hits Sonic, who dodges and realizes he can't land a blow on Goku. However, Sonic surprises Goku with a hit from behind, causing significant damage.
