Tony Stark/Iron Man (Marvel)

Iron Man (Anthony Edward Stark) is a superhero appearing in comic books by Marvel Comics. He is a self-described super-genius, philantrophist and playboy who is usually depicted as the CEO of Stark Industries, a powerful conglomerate. After being kidnapped by terrorists and forced to build weapons of mass destruction, he escapes using a makeshift suit of armor and saves himself. Now finding himself into superheroics, he advances and uses his technological genius to build sophisticated exoskeletal suits of armor and protects the world as Iron Man, becoming a founder and prominent member of the Avengers. In the Marvel Cinematic Universe, he is portrayed by Robert Downey Jr.

Why He Rocks

 * 1) Tony Stark, the man underneath the armor, is a smart, quirky but brave and courageous playboy billionaire that is readily likeable due to his suave and heroics.
 * 2) He was one of the original founders and member of the Avengers, alongside Thor, Hulk, the Hank Pym version of Ant-Man and the Janet Pym version of Wasp.
 * 3) He is basically Marvel's answer to Batman, but less of the brooding, dark and cold-blooded exterior.
 * 4) Legendary actor Robert Downey Jr. portrays Iron Man exceptionally well, so well in fact, it jump started his career after a slump caused by his addiction. Stan Lee himself admitted that he was born to play Iron Man.
 * 5) Although Tony causes trouble on many occasions, he is more than willing to make up for his mistakes, which is also why he became a superhero.
 * 6) Tony is also known for being exceptionally intelligent and innovative, having built an Arc Reactor from scratch in captivity. His intellect has earned him nicknames like the "Da Vinci of Our Time".
 * 7) His Iron Man suits are exceptionally diverse and variying both in appearance, advancement and weaponry. He continues to experiment upon and wear these in his personal leisure.
 * 8) He is very witty, sarcastic and snarky when it comes to dealing with situations both in and out of heroics, which is bound to generate laughter from readers and audiences alike.
 * 9) Thanks to the success of the MCU, the fairly obscure Iron Man has since escalated and became one of Marvel's most iconic and popular superheroes and is now a superhero icon in his own right, appearing extensively in comic books, video games, cartoons and other media.
 * 10) He is also shown to be a capable leader when it came to him the necessity, leading the Avengers when Cap is absent, even yelling the trademark "Avengers, Assemble!"
 * 11) His iconic quote: "I am Iron Man."
 * 12) His sacrifice in Avengers: Endgame is both shocking, and heart-wrenching.

Bad Qualities

 * 1) Tony can rely way too much on his suit at times.
 * 2) As with most Marvel heroes, he was very flawed and did stupid things; most notably, he was an alchoholic and a wominizer before getting sober and settling on one person.
 * 3) His problems and worldviews often caused him trouble with other heroes and his social circle. This is most primarily with his foil Captain America.
 * 4) He manages to set off the wrong people such as the two civil wars he was involved in against heroes like Captain America and Captain Marvel.
 * 5) But despite his rather carefree and overly confident personality, inside Tony's heart lies loneliness, as Ho Yinsen pointed out: "A man that has everything, but has nothing".
