Marvel Mega

Marvel Mega is a relaunch of all of Marvel Comics' titles. Much like DC's the New 52, the relaunch features quite a lot of continuity from the original universe (Earth-616) and incorporates it into the new universe (Earth-727). Due to this, all of Marvel's most popular heroes and villains already exist and have made at least some name for themselves.

Main

 * Anthony "Tony" Stark/Iron Man - a self-described genius, playboy, billionaire, and philanthropist who requires an implant in his chest to keep his heart beating.
 * Peter Parker/Spider-Man - a geeky teenager who has spider-like abilities and is a vigilante after the death of his uncle.

Supporting

 * Virginia "Pepper" Potts - Tony's secretary who has a very dry and sarcastic sense of humor. She helps Tony on his missions by giving him advice over an earpiece.
 * James "Rhodey" Rhodes/War Machine - a former member of the military and Tony's best friend who doubles as his partner. As his suit's name implies, it is built more for combat.
 * Harold "Happy" Hogan - Tony's limo driver and bodyguard whose nickname is rather ironic, has he never smiles and is constantly serious no matter what.
 * Edwin Jarvis - Tony's butler who has been with him all his life. He was a member of the Royal Air Force and, despite his age, he is extremely good in a fight.
 * Arno Stark - Tony's older brother who is smaller and weaker than him. Due to spending a good chunk of his life in a hospital, he is rather anti-social and shy around people.
 * Lana Osborn - Harry's long-lost sister who instantly befriends Peter, eventually growing a crush on him.
 * Harry Osborn - Peter's longtime best friend who is unaware of his dual identity.
 * Harry Osborn - Peter's longtime best friend who is unaware of his dual identity.
