Plot
After stopping Dr. Eggman, Sonic comes face to face with a new threat: a red hedgehog identical to Sonic named Speed, who is faster than Sonic. Later it is revealed that Speed is Sonic's long lost older brother. Sonic is contacted shortly after by an unknown Mobian who is revealed to be Sonic's thought to be dead father, Zoom, who helps Sonic remember a memory of his brother. In the memory, Sonic witnesses his mother murdered by Speed. Speed then proceeds to wipe Sonic's memory by vibrating his hands against Sonic's head, and making him believe that Eggman killed his mother.Zoom trains Sonic to be as fast as Speed is and eventually Sonic exceeds the speed of light and travles back to the night his mother was murdered only to find that it was Zoom who really killed his mom. Zoom erased Sonic's memory of having a brother and of witnessing the murder and then proceeded to frame Speed for it. Zoom then when he met up with Sonic somehow planted a false memory of Speed killing his mother. Sonic comes back in time and teams up with Speed to stop Zoom. Zoom is revealed to be working with Eggman. Zoom says that he killed his wife because she was pregnant with another son and was worried that the three brothers might team up and defeat Eggman. (Zoom was Eggman's secret apprentice at the time.) Zoom reveals that he trained Sonic as he hoped he would kill Speed so the truth about the murder would not be uncovered. After Zoom is beaten Sonic travels back in time to stop Zoom only to be met by Speed who holds up his hand telling him not to. Speed then leaves and Sonic stays long enough to see that the baby was delivered and put up for adoption.
