Archie Sonic X Issue 20 was the twentieth issue of the spin-off Sonic X comic series.
- "Speed Lines!"
Now that Sonic is Station Square's hero, Sam Speed starts becoming really jealous and pushes his car too hard and crashes it. Doctor Eggman sees this as an chance to destroy Sonic. Meanwhile Sam has been acting like a jerk to his team, and bossing them around too much. Dr Eggman, in the disguise of "Robbie Nick", fixes Sam up a car that can go faster than Sonic. Sam proving that he is faster than Sonic uses his new car to fly to the burning oil rig and puts out the fire before Sonic arrives. Sonic is really impressed, but Sam's teammates still think of him as a jerk. Sam is confused by his team's reactions when Dr Eggman reveals his true identity to Sam. He activates Sam's car and it transforms into a giant robot. Sonic too weak to move after a missile attack from the robot is saved by Knuckles. Sam trapped in the robot contacts his team through his wrist communicator to call Chuck to build a negative device to stop the robot. Chuck activates the device and the robot is destroyed and Sam admits he was a jerk and promises he will cool it down.
