Screen 1 – Three years before the Androids arrive
Goku, Gohan, Piccolo, and Sonic train together deep in the wilderness. The air is tense, but their spirits are high as they push each other beyond their limits
Screen 2 – Three years later, West City
The Z Fighters and Sonic gather, waiting for the Androids.
Krillin: "Why here of all places?"
Piccolo: "Two reasons. One, Capsule Corporation is close. Bulma and the others can back us up if things go bad."
Tien: "And two, this is a central hub. If the Androids want to make a scene, they'll show up here first."
Everyone nods, ready for battle.

Screen 3 The Androids arrive
Android 19 and Android 20 appear in West City just like in canon. Goku steps forward and clashes with Android 19. But partway through, his heart virus begins to weaken him.
Goku (clutching chest): "Ngh… the virus… not now…"
Before 19 can finish him, Sonic jumps in.
Sonic: "Don't worry, Goku. I'll take it from here. You focus on the medicine—you'll need it later."
Sonic blitzes forward. His sheer speed leaves Android 19 unable to dodge. A flurry of rapid strikes and a burst of ki slam into 19, leaving him broken and defeated.
Sonic (dusting off his gloves): "Guess you weren't built for speed. Too bad."
19 collapses, destroyed.
Trunks and Silver arrive on the scene, but both look unsettled.
Trunks: "Wait… this isn't right. In our future, the Androids were completely different. They didn't look or act like this."
Silver: "Yeah… the timeline's shifted. Sonic's fight must've changed everything."
Meanwhile, Android 20 (Dr. Gero) realizes he can't win and makes a break for the mountains.
Android 20 (thinking): "I must reach the lab… only then will I have the strength to destroy them!"
The Z Fighters, with Sonic and Silver, give chase—but 20 vanishes into the rocks.

Inside Dr. Gero's Lab
Dr. Gero activates Android 17, Android 18, and a new creation—Metal Sonic.
Gero: "Finally… my perfect warriors. Together, you will obey me and crush the Z Fighters!"
But instead of loyalty, 17 smirks.
17: "Obey you? You're old, weak, and boring. Why should we take orders from you?"
18 (mocking): "He really thinks we're his lapdogs."
Metal Sonic: "Dr. Gero… irrelevant."
Before Gero can react, 17 blasts him through the chest.
17 (smiling): "You're obsolete, old man."
Gero collapses, lifeless.
The trio notice another pod nearby. Android 18 presses the button, releasing Android 16.
Android 16 (calmly): "My mission… is to kill Goku."

The Z Fighters vs. the Androids
Outside, the Z Fighters, Sonic, and Silver arrive just as the Androids step out.
Vegeta (grinning): "So you're the ones stronger than 19? Good. Let's see how you handle a Super Saiyan!"
Vegeta transforms and challenges 18. At first, he seems to hold his ground, but 18 quickly turns the tables. With one brutal strike, she shatters his arm.
When Trunks, Tien, Piccolo, and Silver rush in, 17 intercepts.
17 (bored): "Don't all jump at once."
He dismantles them with casual ease.
Meanwhile, Sonic locks eyes with Metal Sonic.
Sonic: "So you're the tin can version of me, huh? Guess I'll have to show you the real deal."
The two clash, but Metal Sonic dominates the fight, overpowering Sonic's base form.
Android 16 watches silently, unmoved by the chaos.
18: "Well, that was fun."
17 (stretching): "Yeah, but it's getting dull."
Instead of killing the Z Fighters, the Androids pile into a car for the sheer fun of it.
18 (smirking as she starts the engine): "Let's go find Goku."
17: "Now that's entertainment."
The car speeds off, leaving the battered Z Fighters in the dust
