Premise: The X-Men timeline was altered EVEN before the events of DOFP. The X-Men timeline morphed MANY TIMES, not just one. This theory explains all incongruences and errors, and also fixes them once and for all. No Father/Son crap, no similar mutants crap, no ignoring timestamps. For more details: http://x-continuity.blogspot.com NOW...... WHAT IF..... "Legion" is the true and pure "Original Timeline" where the classic X-Men trilogy never occurred and the X-Men never existed to begin with? So: 1- LEGION Timeline - The TV series. Then, David alters the past in some ways. 2- Timeline 2 - X-Men Origins + X1-X3 + Logan Then, the mysterious mutant travels back in 1903. 3- Timeline 3 - First Class + Alternate Origins + Alternate X1-X3 + The Wolverine + DOFP 2023 4- Timeline 4 - First Class + DOFP 1973 + Apocalypse + Deadpool Sounds interesting and fascinating. IMHO.
