In Atlas, we see the headquarters of the Schnee Dust Company as the CEO sat at his desk. 

???: I can't believe this! They just had to go off and leave, didn't they? All of their traces are blocked off! DAMN! 

Jacques Schnee (Weiss and Winter's Father, as well as Willow's ex-husband! He is a vile and bitter man who desires nothing but to keep himself in power over the Schnee Family! Married into it, to gain more power! Enslaved several Faunus to keep the Dust flowing! Voiced by Jason Douglas!) 

Jacques: Am I just surrounded by idiots?! 

???: Maybe that's the problem. 

Jacques: WHAT?! 

He saw the silhouette of a certain fat mustached man. 

Jacques: WHO ARE YOU?! WHAT ARE YOU DOING HERE?! 

???: My dear Mr. Schnee, I believe that we can work together. Your company can be much bigger than it is right now. 

Jacques: You didn't answer my question! Who the hell are you?! 

???: Oh, my apologies. 

The man revealed himself. It was Dr. Eggman! 

Eggman: I am Dr. Eggman, the greatest scientific genius in the multiverse! 

Jacques: How skilled are you really? 

Eggman: I know exactly how to make your company go even faster. You see- 

He snapped his fingers to reveal some Faunus, and- 

Jacques: WHAT?! 

Eggman: They can keep going even faster than before. 

Jacques: These are my workers. How did you- 

Eggman: I roboticized them. Really, as robots, they are even more efficient than ever. 

Jacques: And what would you like in return? 

Eggman: If you swear yourself to become part of the Eggman Empire, then you will receive everything you could ever want. 

Jacques: That is a high price, Doctor. 

Eggman: I know, but believe me, it will be enough to put your daughters in their place. Trust me, I've seen what they can do. I've been foiled by them before. 

Jacques: So, that's another reason. 

Eggman: We have common enemies, Jacques. But you'll be even stronger alongside me. But, you should know- 

As Eggman turned, the security protocols of the building turned off. 

Eggman: I don't take kindly to traitors. 

Jacques: How did you- 

???: Everything has been taken care of, Father. 

A young girl appeared by Eggman's side. 

Sage (An AI created by Dr. Eggman that he takes great pride in! She is considered to be his daughter! Despite coming off as stoic, her love for her father is as strong as his love for her! Voiced by Ryan Bartley!) 

Jacques: Who is- 

Eggman: This is one of my two greatest creations. Her name is Sage. I had her infiltrate your security systems. 

Jacques: That's how you got access in here? 

Eggman: Yes, well, that and- 

Jacques: AGH! 

Right next to him was Metal Sonic, now repaired and upgraded! 

Eggman: I had Metal Sonic here, absorbed several of your machines. He's ready to end your life, if you even think of double-crossing me. 

Jacques: How are you this prepared? 

Eggman: Because failure is something that haunts me all the time. Maybe you can understand. Losing it drives you even further and further. That's why I've been so quiet. Waiting for your enemies to let their guard down. AND THEN YOU STRIKE! 

Jacques: I see. Is there anything else you have in case of an emergency? 

Sage: Now that I think about it, wasn't there that other thing? 

Eggman: Yes, thank you, Sage. 

Sage: My pleasure, Father. 

Eggman brought out a Medusa! 

Eggman: I happened to find one of these little things while during my planning periods. A little test, and it can turn anyone to stone! Alien technology is something to behold, isn't it? 

Sage: A-Alien? So, you're not from- 

Eggman: No, I'm not from your world. I'm a dimension hopper as you could put it. And our enemies are from other worlds as well. That's why I've been building an army with my own devices. Anyway, let's cut to the chase. Do we have a deal? 

Eggman extended his gloved hand to Jacques, and as he paused- 

Jacques: Very well, Doctor. 

They shook hands. 

Eggman: Good, welcome to the Eggman Empire!
