Of course, it wouldn't be. It would be the Superheroes that have been created in that universe. It does not appear random when it's all you've got.
Is there a common theme in my movie example? Cap is a hero out of history. Big green is a mutated human, but as much villain as hero. Blondie is an ancient god. You've got a sharpshooter with no exceptional powers, and a highly trained KGB operative who is as much actress as anything else. There is no theme.
When randomly selecting decks to play SotM, most don't bother with excuses. But I come from a much different background. I played Champions (Hero System). Have been since 1988.
In Champions, creativity is required, if the GM enforces the rules the way they are intended to be. Every Power must have a back story to justify it. Every weakness must be explained. Stories are limited only by the creativity of the author. So, let's hit the random button on SotM video game and see what we get…
Old Man Legacy, Fanatic, and Expatriate vs. Ambuscade in Ruins of Atlantis. Yep, I got an easy one. Heh. Limited only by your creativity.

Paul Parsons was a man of conviction. He was in France, and the invasion in Normandy was going badly. Even with all of his help, the land groaned under the weight of the the war engines of the Reich. They were prepared for this, and ready to throw the Allies back into the sea. Legacy alone was the keeping the front line from falling apart.
Then he felt he was needed elsewhere. The feeling strengthened, and he knew it was true with a certainty he rarely felt. How anythign could be more important than this moment in the war, Paul did not know. The feeling strengthened into an insane conviction he told no one. He was needed elsewhere because others were in dire need, too. And somehow, if he did not make it right, this whole invasion would not matter at all.
When a hole ripped into reality near him, Legacy charged through into the sweltering heat of a desert. He did not know where he would find himself, but America's past was certainly not expected. He did not recognize much, but he did not trust men that wore masks and shot at angels that bled. He also didn't think young girls with modern pump action shotguns should be in a mid-western town, either. And the greenish blue guy wiht tentacles for hair that took a round from a very modern slide action pistol? Definitely not a sight you would see in Kansas, Dorothy.Then the masked man disappeared, but Legacy could tell where he was by the shimmer it left in its wake. When the invisible man laid a round into the non-human, Legacy acted. racing forward, he planted himself between the victim and the coward behind the mask. A single punch shattered the field, and threw the masked man back into a conveniently placed powder wagon. Legacy sighed, knowing his eyebrows would need to grow back. Again.
"Is everyone alright?" He asked.
The young, gun-toting woman said, "Is that…"
"I am Helena," interrupted the angel. "This is Amanda, and the one you saved is M'kk, but if you have trouble with that, he accepts Mack. tempest, are you able to heal?"
"No rain," said Mack. "I just need to wait for it." The sun beat down in a way that everyone knew denied rain for weeks.
"And the masked man?" asked Paul.
"He goes by Ambuscade, but he was once Ansel," stated Expatriate. "Assassin. Hunter. Remorseless killer. We got thrown here from…"
Again, the angel interrupted. "Another time. Another place. One that we should not discuss."
"You know who I am, Amanda?" Paul asked as he ignored the angel named Helena.
"You are important," said Helena. "You may be less important if she answers your questions. You are in 1883. You need to get back to…?" Helena trailed off.
"1944. Normandy. But the portal closed behind me."
Helena nodded. "Yes, you must get back. As must we, and Ambuscade. A friend of ours, with the unlikely handle of Chrono-ranger, told us where to go if we ever found ourselves in the wrong time. We need only go there, leave a message for him to find, and he will return us all."
"And where is that?"
Amanda answered, "Atlantis." Paul smirked. "Seriously." Paul chuckled. "She's got wings. I've got the heavy calibre guns. Which one of us is less likely to think Atlantis exists?" Paul paused for a second, realizing she was stating this as fact.
"I guess I get to find Atlantis," stated Paul.
"No, Atlantis finds you. You're lost. It knows exactly where it is," advised the angel. "Can you carry Ambuscade?"

Not hard. You can also switch it up so Expatriate and Fanatic are accidentally thrown back in time by an Apostate / Citizen Dawn team up at the Tomb of Anubis, and land in WW2 Europe needing Legacy's assistance toget home. I dislike WW2 Legacy jumping forward to the future. But you could ice Cap him. Heh. The AG Legacy unlock just matched the villain too well, so i incorporated that into the story.
So the answer to the random question? In comic books, any team-up can be justified.
