In Sunset City, a Zombot Shadow holds Sonic by the throat up against a truck as Rouge looks on in astonishment.

"Thought you can take them on, with raw power, when this all over I can't wait to I told you so. If you don't crush me first..." Sonic exclaimed then kicked him off. "A healthy Shadow would've seen that coming and countered it... dealing with you and a bajillion zombots? Not so good..."

"Is everyone loaded up?" Sonic asked.

"We just finished!" Tempest said.

"Then get out of here! I'll cover you!"

"Thank goodness for these noble self-sacrificing types," Rouge said as she and Tempest got in.

"Let's just hope that Twilight and others can help before it's too late," Tempest said as the truck took off.

As Rouge drives off with the truck and rams several Zombots, Sonic realizes that he would be fighting an entire city by himself. Luckily, Omega reveals that he stayed behind as "Eggman's robots" were still present and he needed to deal with them violently. Sonic teases Omega and says that he stayed back to help him specifically, which annoys the robot. As the two fight side-by-side, Sonic soon spots Shadow running after the truck of the uninfected citizens.

"Not so fast when you don't know work your rocket skates are ya?" Sonic asked as he attempts to drag the Zombot back with him but Shadow instead tosses him back to Omega. The robot detects that Sonic's infection was spreading further due to him fighting several Zombots and suggests for him to retreat. Sonic refuses as he did not believe the truck was far enough away and he did not want to leave another friend behind as he tried to cure himself. Omega clarifies that they are not friends and that Sonic was only getting in his way. As Omega cannot destroy the Zombots, Sonic suggests that they both retreat instead but the former stubbornly refuses. Following this, when Shadow lunges at Omega, he grabs him and slams the Zombot into the ground. Sonic reminds Omega that he was fighting Shadow but the robot only saw him as another Eggman robot that needed to be destroyed. The duo keep up the pressure on the Zombots but Omega soon has his chest ripped open by Shadow and his arms ripped off by two other Zombots. Sonic pushes Shadow away from Omega and tries to get through to his rival but to no avail. The hedgehog tries to get Omega to retreat but the robot refuses again, wanting either victory or death. Sonic finds himself on his knees surrounded by several Zombots and the virus nears its completion.

"Sonic!" Sliver shouted as he and Twilight levitated them all.

"We've cleared a path for you! Run!" Twilight exclaimed.

"The Tornado is just outside of the city to the east! Meet us there!" Tails shouted then Sonic boosted out of the east side.

"He's clear! Drop them all and cover me while getting Omega!" Rainbow said as Twilight and Sliver dropped them and Rainbow grab the remeant of Omega.

Observation: You are strong to lift all my mass with little effort.

"Yeah about that..." Rainbow sheespliy said then regroup with the others. "I got the bot! Let's blow this joint!"

...

Later at the Restoration HQ.

"I just want to thank you for rescuing me at the last moment, I owe one," Sonic thanks Sliver.

"Actually it's twice you owe him," Pinkie came in.

"Your keeping count?" Spike asked.

"Cleary Sonic isn't."

"There been some things have been on my mind," Starlight spoke to Sliver. "For instance remember- you told us when you returned to the future, only to find the world metallic and lifeless. Do you think it was The Metal Virus?"

"I'm sure of it, and while things are bad now, hopefully with me here we can stop it before it destroys the world," Silver said.

"But never mentioned Zombots though," Rarity implied.

"That's the thing, I didn't see anyone."

"Hopefully, we won't need to solve that mystery," Applejack said.

"Back on the matters at hand, today was a close call. Too close are we any closer to figuring out the Metal Virus?"

"No," Twilight told him. "The analysis that Trixie and I took wasn't robust enough but I have a solution. Your speed is not completely combating the Metal Virus but consistently beating it back. I'm creating a sensor that can read your biometrics while you run. Hopefully, it'll give more insight into the Metal Virus and how it's reacting to your system."

"Only problem is, the computers can't handle that kind of data," Tails said. "I've got a lab in a Central City that can... If Eggman doesn't attack there. If that happens it will be dicey getting in there and doing the analysis."

"I can cover for you!"

"But what if you're called somewhere else?"

"Let's Hope that It won't happen?"

"Silver's right!" Pinkie hugged her friends except for Sonic. "We have to stay positive, and the doo hickey that Twilight gave Sonic... I'm sure that things will get better from on out!"

As that does for the Infection Story Arc, Tomorrow the Last Minute Arc
