With official reports pouring in that Michael Keaton is set to return as Bruce Wayne/Batman in 'The Flash', speculations are rife that this will be a Flashpoint film and will adapt the comic storyline that had some unbelievable ramifications. One of these might even tie Matt Reeves's 'The Batman' as it suggests Robert Pattinson's version of the Dark Knight will be part of the multiverse although the film is ideally a separate entity. For now, DCEU's last Batman was Ben Affleck.

Affleck played the role in three films, 'Batman v Superman: Dawn of Justice',  'Justice League' and a cameo in 'Suicide Squad'. But with him most likely hanging up his cape and cowl, the film may look at bringing in Flashpoint to better explain the multiverse theory, a world where we saw the possibility of three Supermen existing (Watch 'Crisis on Infinite Earths'). The comic plotline for Flashpoint sees Thomas Wayne becoming Batman in an alternate universe after Barry Allen fractures the timeline.

While there is no confirmation that Jeffrey Dean Morgan will play the part, it may actually fit Keaton here who will play the role of a mentor.Fans have already theorized him to be like Bruce Wayne in 'Batman Beyond'. The bigger question is, will this bring Robert Pattinson's version to the DCEU? Ideally, it's complex and unlikely.  Even though popular fan theories on Reddit do suggest that they tie 'The Batman' to the DCEU events (assuming Flashpoint is the story they go with).

If this is indeed the case, then we might just witness the presence of multiple Dark Knights in alternate universes. This can also add a whole new layer to the Batman story. Comicbook has a rather interesting theory where it speculates The Batman trilogy could be an origin story that would answer how Pattinson's Bruce Wayne will be Gotham's masked vigilante. His character could set up the introduction to other DC heroes through Flashpoint. In addition, the film just might also establish that a multiverse does indeed exist.
