Screen 1 – Saiyan Arrival
One year ago: Raditz has already been defeated. Suddenly, Vegeta and Nappa arrive on Earth with their Saiyan pride and intent to conquer the planet.
The Z Fighters immediately gather: Piccolo, Krillin, Gohan, Tien, Yamcha, and Chiaotzu.
Sonic is also present, excited to test his power and strategy in a real battle.
He is here not just to protect Earth, but also to see how far he can push his abilities.
Screen 2 – Saibamen vs Z Fighters
Nappa plants the Saibamen near the Z Fighters.
Yamcha fights his Saibamen and is almost killed, but Gohan intervenes in time, saving him.
Meanwhile, Nappa notices Sonic and challenges him.
Fight starts:
Sonic initially uses 50% of his base power, dodging Nappa's attacks and landing precise counters.
Nappa is slightly injured and shocked that an Earthling-level being can even block his strikes.

Screen 3 – Dark Sonic Awakens
Sonic decides to unleash his full power.
Vegeta observes his scouter: 4,000 PL — enough to rival Nappa.
Sonic activates Dark Sonic aura, throwing punches that Nappa can barely block.
Dark Sonic effortlessly solos Nappa, leaving him heavily injured.
Nappa (panting, shocked): "Low-class Saiyan… beaten by… a hedgehog?!"
Vegeta is stunned: he realizes Sonic's potential far surpasses what he expected from Earthlings.

Screen 4 – Goku Arrives
Goku arrives just in time to witness Dark Sonic in action.
Base Sonic remarks: "I'm not even at full Dark power yet," hinting at further capabilities.
Goku vs Vegeta begins as canon.
Meanwhile:
The Z Fighters finish off the remaining Saibamen without any deaths this time, thanks to Sonic's speed and strategic interference.

Screen 5 – Great Ape Vegeta & Dark Sonic Power-Up
Vegeta transforms into Ōzaru (Great Ape); his base 18,000 PL multiplies 10x → 180,000 PL.
Sonic watches carefully and decides to combine all Chaos Emerald colors (purple, blue, red, yellow) in Dark form:
Dark Sonic PL: 100,000
He also creates a sphere of shadow energy splitting into 30 Dark Sonic clones for attack patterns.
Sonic uses Spin Dash + Kamehameha fusion (Dark + Emerald energy) to push Great Ape Vegeta.
Even with this, the full power of Great Ape Vegeta overwhelms him.
Key points:
Dark Sonic's attacks are devastating but cannot outright defeat Great Ape Vegeta.
The Spirit Bomb + Kaio-ken x3 Goku combo is still needed to balance the fight.

Screen 6 – Climax
Sonic continues to assault with all his Chaos Emerald energy and Dark form abilities, creating a Kamehameha fusion blast to help weaken Vegeta.
Yajirobe cuts Vegeta's tail, returning him to base form.
Vegeta loses the fight, just like in the original Saiyan Saga.
