Okay, so I'm only on episode 10 of season 3, so I dunno what happens, but I'm just gonna create an AU where iris dies and Caitlin goes all killer frost. Barry/Julian

A war is coming and a fangirl is determined to stop it.

This takes place when Cas is still crazy. A woman appears out of nowhere and claims she's from an alternate universe. She says she's around Jo's age and insists on getting to know them better.

Dean is caught by surprise by a shapeshifter while trying to kill it. Sam doesn't realize that anything is wrong at first. He figures out fairly quickly though.

The avengers go back in time to Tony's school because Tony accidentally exploded a machine during a debriefing. The new additions are there as well. Loki is also there. This is set after infinity war but no one is dead. They appear in a secluded area when the students are having lunch. Oh, and also, Pepper is about to give birth.

Inspired by a head cannon on Pinterest. John is on a date but Sherlock texts him to come back to Baker Street for urgent business. When he gets there, Sherlock tells him that they are out of milk. John is pretty upset with Sherlock.

One shots of Dr. Strange and Ross meeting Sherlock and John.

This takes place in the middle of infinity war. Instead of Thanos going for vision's stone, he sends the avengers and Thor and Loki back in time. They are teleported back in time to Asgard when Loki and Thor were little. Loki is then brought back to life in front of all the asgardians.

Annabeth is having a family reunion and is bringing Athena and Poseidon. Percy is a true seaweed brain and brings Loki and Thor along. The rest is history. Oh and also, a certain high functioning sociopath just happens to live next door.

The same thing at the end of Thor: Ragnarok except they are ready and have a few people to help. A few demigods. The rest is just them meeting the avengers.

One shots of Peter and the avengers. After Infinity War, but in an AU where no one is dead.

Peter hadn't expected to be kidnapped. He certainly didn't expect to be kidnapped with two enemies. But along the way, he discovers that one is not so bad after all and the other, well, the other is no different. After this, there are just one shots of the ship in action.

John finds out that Sherlock is a demigod and they visit camp. Sherlock has a lot to catch up on. Also, a certain doctor with magic pays them a visit.

Sherlock visits Tony.

This is before the last vow. Sherlock and the others watch Sherlock get shot and sees what will happen.

Peter goes on a field trip to SI with his classmates. What could possibly go wrong?

If you haven't watched infinity war, don't read this. So this is basically how I think people would react if Spiderman, groot, star lord, and others came back to life
