The Forgotten Avengers
The MCU has so far given us a total of eleven Avengers -- Black Widow, Captain America, Falcon, Scarlet Witch, Vision, War Machine, Iron Man, Hulk, Hawkeye, Thor, and briefly Quicksilver.
With over fifty years of comic books, it's understandable that some members of our favourite superhero team might be left out. Let's take a look at some of them...
Hercules
Like Thor, Hercules is based on a mythological figure -- in this case, it's the guy from that Disney film! First appearing in 1964, Harry "Hercules" Cleese was a regular with both the Avengers, and Thor's solo adventures.
While many of the new Avengers to join the roster at the end of Age of Ultron were near-equilivants to the leaving members, Thor didn't have a like-for-like replacement. Maybe they could have replaced one legend with another?
Ms Marvel
Ms Marvel is up there with similar characters Doctor DC, Professor Sony Studios, and Mr Self Congratulator. We jest, of course. Carol Danvers has also been known as Warbird, which we happpen to think is a much cooler name.
After a number of eponymous adventures, she was an occasional member of both the Avengers and the X-Men. It is easy to see why she may be overlooked in any adaptions of either franchise however, as her character was developed to mirror the then-modern woman's "quest for raised consciousness, for self-liberation, for identity", which in an age of equality might make her seem dated.
The Wasp
One of the original founding members of the Avengers. With her simmering wings and ability to shoot bioelectric blasts, comparisions have been made to the portrayal of Angel Salvator from X-Men: First Class.
One of her key abilities is being able to change size -- she can shrink super small, or grow hugely huge. As this is quite similar to Ant-Man's sole reason for existing, she probably won't be joining the MCU any time soon, unless she is portrayed in a similar manner to the aforementioned Angel.
The Swordsman
Everyone loves an anti-hero. The Swordsman was original a villain, and enemy of Hawkeye. Once a freedom fighter, he was a longtime adversary of the Avengers, before meeting and falling in love with Mantis, and joining the Avengers permanently.
Hawkeye was (in our opinion) certainly the most interesting and best developed Avenger from the movies, so it's hard to see where him having a specific foil would fit in without losing anything. Could he have stayed for an extra movie, in order to introduce Swordie?
