This is Sonic inbetween the Sonic 3 and Sonic Adventure DX and same goes for Tails.And the Super Forms differ in power for each Saga.No Super Forms in this chapter,though!

The Z-Fighters saw that Sonic and Tails had arrived.Sonic watched in silence,though intrigued.Tails waved to Gohan as Sonic actually...chuckled.Vegeta was unimpressed.Nappa said,"RATS are your last resort besides Kakarot.HAHAHAHA!" Sonic glared at Nappa and kicked him in the face.Nappa stumbled.Sonic speed-blitzed Nappa.Vegeta was slightly confused."This isn't right,the blue rodent's power level is 1,500." The Prince Of Saiyans said curiously.Sonic let out a yell of power. "NAPPA,HIS POWER LEVEL ROSE TO 4,500!" Vegeta informed Nappa. "Your scouter must broken.Oh well.BOMBER DX!" Nappa hurled the giant blast at his foe,whom slapped it away.Sonic jumped into the air,curled into a ball,and hit Nappa."...How'd you......like that?....That was...my Homing Attack..." Sonic said,as though his voice often left to nowhere.Nappa went all out,and Sonic yelled once more."6,500?!" Vegeta said.'How can a rodent contain more power than a Saiyan?' The Prince of Saiyans thought to himself. Sonic smirks. "Ready...?" He asks before unleashing a Spindash on Nappa.Goku arrived."Nappa's having trouble! I will deal with Kakarot." Vegeta said. They flew off.Meanwhile,Sonic and Nappa's battle continued until Sonic felt some power burst.Upon seeing that,Tails got the Z-Fighters away. "Oh no,not n-AAAAAAARRRRGH!" Sonic screamed.Rainbow Choas Energy exploded from within him,which engulfed and killed Nappa.Meanwhile,Goku and Vegeta fought,with Goku being the victor,but Vegeta escaping.
