With more recent years, Luke Cage has gained a great deal of exposure and recognition, with both his own self-titled Netflix series and the crossover mini-series The Defenders being notable examples. Much of the recent surge in popularity can likely be attributed to the Brian Michael Bendis run on the Avengers, during which Luke first joined the team in 2005 with New Avengers (vol. 1) #3.
Despite his long-time crime-fighting partner and friend Danny Rand aka the Iron Fist appearing on a few occasions, Luke Cage has only had one brief appearance in the MC2 and it's not even really him...let me explain.
In Avengers Next #1 (January 2007) the MC2's current roster of Avengers are unable to stop the theft of various Avengers blood and tissue samples by the teleporter known as Warp. These samples are delivered to Sylene, a sorceress and the daughter of Loki, who uses the samples to create 'magical clones' to attack the Avengers as a diversion.
Logically, if these were samples from past and present Avengers members and Luke Cage's 'magical clone' appears amongst the shambling monstrosities, Cage was at some point a member of the team in the MC2. This is likely a nod to Cage's longstanding membership over in the Main Marvel Universe. We get the only mention of the real Luke Cage shortly after, when American Dream points out that the monstrosities can't be actual corpses, 'Not with duplicates of Haweye, Cage and the rest of us who are alive.'
And that's about all we know of the Hero for Hire. He's still alive in the MC2 and he was a member of the Avengers prior to the current team founded in A-Next #1. It also seems Luke is known simply as 'Cage', in the same way he was referred to in the 90's. To stray into the world of wild speculation, the most likely placement for Luke's time on the team would be at some point between the (admittedly vague) divergence point between the Main Marvel Universe and the MC2 before the original team was almost entirely wiped out on their last mission. Alternatively, Cage may have served as a member of the interim team that existed for some 18 months afterwards alongside members such as Speedball, Nova, Jolt, Jubilee and the Steel Spider.
Possibly completely irrelevant, but I felt I should point out that Cage's copy is wearing a version of his original costume, complete with tiara. Whether this indicates when the sample was collected from the hero or that he returned to his original costume at some point is unclear. Considering other 'magical clones' aren't wearing their heroic counterparts current costumes, this is probably nothing more than an artistic choice.
If anyone has any insight on this, admittedly very minor point of continuity, please let me know! Until I stop picking apart the very fabric of the MC2-niverse, I remain
