Yes, Quaternity is in fact a word. It’s like a fraternity, but with only four members. Congratulations to Eli Manning, Tom Coughlin and the New York Giants on being Super Bowl Champions. Along with ‘the big game’ came a plethora of ridiculously expensive commercials, one of which was a fresh new trailer for Marvel’s blockbuster superhero ensemble franchise The Avengers. The four main characters of Marvel’s the Avengers happen to closely correlate with the four basic personality types. What a strange coincidence. Let’s go right on ahead then and take a look at Earth’s Mightiest Heroes.
Captain America is the stalwart, stoic, and commanding ‘first avenger’ who defends justice with his iconic and indestructible shield. The Sentential of Liberty is characterized by his tough-minded demeanor, his unyielding physicality, and his disciplined mindset. Dutiful, authoritative, and highly dependable with a strict code of ethics Captain America is a classic Guardian. A born leader, Captain America ‘lead’s by example’ and is the back-bone of the Avengers, much like Guardians are the back-bone of society.
The Hulk is a wild, ferocious, raging humanoid monster that comes out when Bruce Banner gets excited. The not-so-jolly green giant was inspired by the classic tale of Dr. Jekyll and Mr. Hyde, and is characterized by his instinctual nature, his overpowering physicality, and his fearless disposition. Impulsive, audacious, excitable, and highly physical The Hulk is representative of an Artisan. Indeed The Hulk is often called in for serious jobs that require a creative solution, much like Artisans are in many organizations.
Iron Man is an intelligent, inventive, and ingenious engineer who created a mechanical suit to save his life. The Armored Avenger is characterized by his mechanical aptitude and inventive genius, being a billionaire industrialist Stark is constantly tinkering with and improving his mechanical suit. Innovative, scientific, analytical and systematic Tony Stark makes for a wonderful example of a Rational. Certainly Stark is the brains of the Avengers and uses his cold, analytical mind to keep him and his super-friends on the right track.
Thor Odinson is a mystical, altruistic, brave and mighty warrior from another world who fights primarily for his native realm of Asgard. The God of Thunder is characterized by his noble demeanor, his humble yet high-spirited attitude, and his selfless acts of valor. Diplomatic, enthusiastic, empathetic, and highly independent Thor makes for a great example of an Idealist. Thor is the glue that holds the Avengers together, and is always sacrificing himself for the greater good.
I’m loyal to nothing…except the American Dream. 
My kingdom for a Radio Shack.
… You won’t like me when I’m angry!
Even the life of a Thunder God can offer no greater satisfaction than this! For I have helped a fellow man!
