In Uncanny X-Force #20, a member of the Captain Britain Corps claims that Fantomex is an anomaly and does not exist in any other dimension. Yet, alternate reality version of Fantomex have been shown numerous times.
- Days of Future Now (Earth-5700): Fantomex became the host of Sublime.
- Here Comes Tomorrow (Earth-15104): Fantomex has become one of Sublime's U-Men and is known as Apollyon the Destroyer.
- Even in an earlier issue of Uncanny X-Force we see Fantomex fighting a Deathlok version of himself.
Is there an in-universe explanation for this or is it simply a retcon?
