You. Are a loner. You don't like interacting with living beings... keyword living. But hey! Now your here. At a party.
...
Time to go home. BUT NO!!! Instead of just WALKING HOME you stray off the path a TOUCH A GLOWING RI- SCRATCH THAT. YOU TOUCH A HOLE THAT LOOK LIKE IT WAS MADE WITH A BENT, BROKEN, DULL RUSTY SPOON THAT IS FLOATING... and you touch it. You accidentally fused with the void, the all-spark, and all the infinity gems at the same time you touched the rift.
So now you don't only have to adjust to taking care of one pair of skeletal bothers and a handful of autobots, and the avengers. You also have to deal with alternate versions of the bros, decepticons, and thanos.
...
This is what you get.
