Mario and Sonic have very peaceful lifes, even though they have to risk them everyday to fight for the freedom of their friends. How about we look at what theyre doing in their respective dimensions?

As our hero got his day off, he immediately wanted to go to a festival. Sadly, hes late and runs through the Green Plains as everyone is waiting for him. After a short time, he stops to breath for a second. Hes at the top of the hill, looking at some forests.

"Wait… whats that?" The forest seems to quickly disintegrate. As it seems to quickly spread, Mario runs again to get to the festival.

Sonics dimension

Sonic tries to help his friend, Tails, with his newest machine. While Sonic didnt understand what Tails was blabbering on about what the machine was and how it worked, he did understand that he had to collect the parts of the machine and where to find them. He went to Tails other workshops, Eggmans base, got some Emeralds from Angel Island, trashed some badniks and so on. Finally, he gave Tails the parts and went to get some food.

As he comes back, Tails workshop and all the space around it is gone, only a black hole is left. "Tails? Tails? TAILS!" As more and more space is disappearing, Sonic runs away.

Marios dimension

Mario finally reaches the festival. As he meets Luigi, he finally stops running. "Luigi... evacuate... theres a problem!"

"A problem? Whats going on?"

"Forest… disappearing… I… dont know why, but…"

"Calm down, bro, pull yourself together and tell me what happened, but slowly."

"Alright." Mario breathes. "I ran through the plains and paused for a second. But then I saw the forest basically getting deleted piece by piece. This process keeps going on, more and more is getting deleted. Its spreading. We need to get everyone somewhere safe-"

"Um, b-bro?"

"Yes?"

Luigi shivers. "A-are y-you talking ab-b-bout this?" He points somewhere into the mass. The festival, together with the people starts disintegrating, as something that looks like a black hole gets bigger.

Mario shivers as well. "W-where is Peach?"

"S-somewhere in t-t-there."

"Oh, no." They are unable to move as they see the horror of everyone getting disintegrated.

Luigi is the first one to act, he shakes Mario and runs away with him.

Sonics dimension

Sonic got away from the black hole, only to find more and more popping up. As he finally gets to the his friends homes, he only sees the absence of them. Sonic only has a single thought. He needs to save whoever is left.

Marios dimension

Luigi and Mario keep running through the plains, running from the black hole-lookalikes as more appear over the land. Eventually, they end up in the Mushroom Castle, as everything else is gone.

Sonics dimension

No one is left. Sonic is alone. Sonic had nothing else in his mind as he ends up on a random hill with nothing around him. Suddenly, theres some kind of portal next to him. With nowhere else to go, he reluctantly goes inside it, not knowing where it leads.

Marios dimension

Even the castle starts to get sucked into black holes. They get up on the roof to escape, it was too hectic to think about anything else. Eventually, theres nothing left, except for the roof. As the black holes keep extending, things seem worse by the millisecond. Luigi thinks about a way to save his bother.

"Mario."

"What?"

"Sorry." Luigi proceeds to throw Mario higher up the roof, protecting him from the closest black hole and getting sucked in himself.

Mario is now alone. Alone on that roof.

Or is he? Mario sees a portal opening. Figuring that its his only chance to survive, he enters.

Oh. So that's what they're doing.
