1. An ant nest.
EX. Who is Ant-Man?
Ant-Man as portrayed by Hank Pym (alongside his often parter-in-heroism, love interest and/or wife (or estranged ex) The Wasp as portrayed by Janet van Dyne) is a founding member of the Avengers in the Marvel Universe. He has no super powers. So what does he bring to the table when you have a god, a guy in a robot suit, a super patriot and The Hulk are already sitting at the table? While Tony Stark is a brilliant scientist, Hank Pym is probably an even more brilliant, though as you'll find out very tortured, scientist.
Originally, Ant-Man's specialties included shrinking and communicating/controlling ants and other insects. These are useful abilities but it is probably obvious as to why he probably had some trouble standing out on the Avengers. Hank Pym's feelings of inadequacy and emotional instability have weighed heavily on him over the years and he tried to rise to the challenge by changing his identity dozens of times: he has been Giant Man, Goliath, a male version of the Wasp, just Hank Pym, the infamous Yellow Jacket and many other personas. He also, contrary to the new Avengers film, is responsible for the creation of Ultron.
Often, his creation of Ultron is meant to be to one-up the robotics skills of Iron Man but, unfortunately, his relationship with Ultron is worse than Frankenstein and his monster. Ultron is one of the most deadly super villains in the Marvel Universe and has attempted to eradicate mankind dozens of times. This is really indicative of Hank Pym's unfortunate fate in comics as he never gets the respect he deserves, despite being one of the smartest people in the Marvel Universe (as I said he is arguably much smarter than Tony Stark and often butts heads with Mr. Fantastics for supremacy as super scientist numero uno). He always is the guy who reaches too far or not far enough and winds up creating a problem while trying to be the hero.
And honestly? That makes him a pretty interesting character.
Unfortunately for fans of Pym but convenient for Marvel, since Pym is unfortunately always associated with abusing Janet in the comics despite the fact that was an example of his emotional instability and not really a full picture of the man or the fact that many Marvel heroes have done worse, Hank Pym will be the mentor in this film. The hero instead will be small time crook turned hero Scott Lang, who got his start stealing super science to help him get the help for his sick daughter, and his redemption story should make for a pretty fun film.
Especially starring Paul Rudd as the titular Ant-Man.
