When Hank Pym arrives in 2018 to rescue her, he finds a zombefied version of his wife, who attacks him causing him to be infected as well.

King Killmonger: 2009 (While deep undercover, Killmonger discovers a plot to assassinate Tony Stark and decides to use it to his advantage to start a war between Wakanda and the United States)
Party Thor: 965 (Rather than taking the abandoned Loki for himself for future diplomatic relations, Odin decided to return him back to his family thus establishing a more peaceful relationship between Asgard and Jotunheim. Odin would continue on to have close, peaceful relationships with former enemies, creating a time of peace among the realms and leaving Thor a reckless, spoiled only-child.)

Nove Corps Nebula: 2014 (Ronan somehow manages to kill Thanos and conquers the universe. An injured Nebula is rescued by Nova Corps a made a member, though because they are unable to beat Ronan, they instead decide to lock down Xander, closing it off from the rest of the universe)
1988 Avengers: 1988 (Yondu finds Peter Quill and rather than adopting him, he does what he's done before and take him to his father. Given the powers of a Celestial, Peter decides to visit Earth one last time with his father allowing him to so he can destroy and absorb it for him)

Tony Stark on Sakaar: 2012 (Iron Man blows up the Chitauri fleet during the Battle of New York but this time fails to make it back through the wormhole, leaving him to get warped to Sakaar. Gamora, who is sent by Thanos to assassinate him, follows him to the trash heap of the universe)
Kahhori: Thousands of years ago (Ragnarök occurs and Surtur manages to destroy Asgard, causing the Tesseract the float through the depth of space, eventually landing on Earth where the Haudenosaunee Confederacy would be located. Members of the Mohawk people would eventually accidentally stumble upon where the Tesseract was located and be transported to an alternate realm that they call the Sky World. This group decides to live there in peace, closing them off from any hardship from their original dimension.)
Hela Banished on Earth: 959 (Rather than banishing Hela to Hel, Odin decides to do what he did to Thor in the original timeline, stripping Hela of her godhood and sending her to Earth, where she'd land in China and encounter Xu Wenwu)
1602: 2018 (This dumb as **** episode has Captain America accidentally hitting the time stone while battling Thanos, causing a ripple that would fuse the present with the year 1602. Captain Carter is involved for some reason)
Mecha Avengers: 2015? (They don't explain it in the episode, but since Ultron appears in cartoon, the events of Age of Ultron must have occurred. As such, its reasonable to assume that this is a timeline where Hulk decides to return to the Avengers rather than head into space. Grief stricken over the events that occured in Africa, Bruce Banner is at a new low but Sam Wilson tries his best to help him out. Though whe another Hulk incident occurs, Bruce Banner decides to get rid of the beast once and for all, but all this does is release a new gamma monster onto the world, leading to the first gamma war.)
Celestia Agatha: 1947 (The episode takes place on that date, but the events that leads up to it probably happened earlier. Agatha finds out about the god living in the core of the planet and decides she wants a piece of that. She proceeds to absorb the Eternals powers to perform a ritual to take Tiamut's power for her own, but requires the resources to create such a large ritual and the last of the Eternals, Kingo. She decides to play with Howard Stark's ego, making him get into the movie industry.)
Russian Roadtrip: 1991 (Red Guardian finds out about the plan to steal the Super Soldier Serum from Howard Stark and decides to join that mission rather than live in Ohio undercover)
Emergence: ??? (You'd think this shit happened in 2024 like the normal timeline, but apparently it happened earlier from what I've heard which makes no sense to me at all. My only guess would be that they killed Thanos before he performed the snap and the emergence happened in 2018)
1872: 1872 (That's right, not even a universe where everything is still the wildwest but instead everything is in the past for some reason.)
