the merc with a mouth VS the jerk with that jaw Wade Wilson's early life is mostly unknown. His mother died of cancer while he was young and his father (who was in the military) was physically abusive. Wade was a deliquent in his teenage years, possibly to spite his father. However one night while drinking with his friends his father attempt to take him out of the club one of his friends stole Wade's Fathers handgun and killed him. Following a brief stint of military service, Wade began his mercenary career while still in his late teens. Accepting assassination jobs only against those whom he felt deserved death, he made a habit of using plastic surgery and technology to take on a new identity whenever he failed an assignment. Many years later Deadpool's nemesis T-Ray accused Deadpool of killing his wife and stealing his identity after a failed mission, but Deadpool's restored memories revealed this to be a lie; in T-Ray's account Wade was wearing his Deadpool costume, which he didn't have in till after he joined Weapon X.
On Saturn's moon of Titan lived a colony of Eternals, and Thanos was born as one of the last sons of the original colonists, Mentor and Sui-San. However, he was born misshapen and monstrous in comparison to the other Eternals, particularly his handsome and carefree brother, Starfox, and Thanos grew into a melancholy, brooding individual, consumed with the concept of death. More than any of his people, Thanos sought out personal power and increased strength, endowing himself with cybernetic implants until he became more powerful than any of his brethren. At some point, he was exiled from his community, although the accounts differ as to its cause. Some say it was because he committed a crime by being the first to create a weapon. Thanos himself once claimed that he vivisected his own mother in an attempt to investigate how someone consumed with death such as himself could have come into being. marvel wins such as deadpool !!!!!
