In DC's Metal event from Scott Snyder, we were introduced to the Dark Multiverse and a number of twisted versions of Batman, including The Batman Who Laughs and the Red Death. The latter was a version of Bruce Wayne desperate to accomplish more, who absorbed Barry Allen's Speed Force abilities, killing him in the process.
During last night's episode of The Flash, Barry and Iris found themselves in the Flash Museum's Hall of Villains and saw a video with Central City Police Captain David Singh talking about Cicada's killing spree - and he namedropped the Red Death!
"The Flash did everything he could, but Cicada killed more people than Zoom or even the Red Death and the way the city saw the Flash - his legacy - was never the same," Singh explained.
If this is indeed a hint that the Red Death will be season six's lead villain, then The CW series is clearly going to return to using a speedster as the big bad and that may be no bad thing due to how underwhelming both The Thinker and Cicada have been.
Chances are, it won't be Bruce Wayne beneath the mask and will probably be a twisted version of Barry instead. However, we might see a mystery unfold regarding his identity - another plot beat which has been sorely missed after the first three seasons. Thoughts?
