My Take on The Cell And Trunks Timelines

Timeline 1 (Original Timeline) - Goku kills Frieza and King Cold but dies from virus. All Z fighters dead by Androids except for Trunks. Trunks goes back to the past to warn about Androids. Trunks returns from the past and defeats Androids using remote control technology made by past Bulma but because he doesn't get Ascension training due to lack of knowledge about Cell's existence, Timeline 1 Cell sneaks up on Trunks and kills him, steals his time machine, and time travels to past. Bulma is left alone with nobody.

Timeline 2 -Timeline 1 Trunks arrives, kills Frieza and King Cold, gives medicine to Goku, and warns about Androids. Z fighters and Trunks prepare and defeats Androids using remote control that Bulma made but they all never learn about Cell's existence. Trunks takes remote control technology and goes home to Timeline 1 but Z fighters never see him again because he's killed by Timeline 1 Cell. We don't know what happened to the Z fighters or baby Cell in Timeline 2.

Timeline 3(The TV show we all know and love) - Timeline 1 Cell arrives to a point before Timeline 1 Trunks arrives creating Timeline 3. The Trunks that we see in the show would later arrive from the future into this timeline to warn about the Androids is no longer Timeline 1 Trunks but Timeline 4 Trunks because the original Timeline 1 Trunks was killed by Timeline 1 Cell.

Timeline 4 (The History of Trunks) - Goku defeats Frieza and King Cold but dies from virus. All Z fighters dead by Androids except for Trunks. Trunks goes back to the past to warn about Androids thus turning himself and his timeline into timeline 4.

Back to Timeline 3- Timeline 4 Trunks arrives, kills Frieza, gives medicine to Goku, and tells Z fighters about Androids. Timeline 1 Cell is suprised to see Trunks because he thought he had killed Trunks but Timeline 1 Cell had no idea he had indirectly created Timeline 4 when he time traveled to a point before Timelime 1 Trunks arrived. Bulma makes a remote control to kill the Androids but Timeline 1 Cell foolishly tells Piccolo he is from the future where he killed Timeline 1 Trunks. Timeline 4 Trunks and Krillin goes out to kill Timeline 3 baby Cell in Gero's lab. Timeline 4 Trunks trains with Vegeta to become Ascended, Krillin destroys the remote control, Timeline 1 Cell becomes Perfect but is killed by Gohan. Timeline 4 Trunks goes home.

Timeline 4 (Ascended Future Trunks) - Trunks returns home and kills Android 17 and 18 using Ascended power instead of remote control. Timeline 4 Cell tries to sneak up on him like in Original Timeline 1 but is no match for Ascended Trunks. I feel bad for Timeline 4 Cell because he had no idea a Timeline 1 Cell existed and had time traveled to indirectly make Timeline 4 Trunks train to become an Ascended Saiyan during Timeline 3.
