Albert Wesker is the main antagonist of Resident Evil. He is a power hungry man and wants to rule the human race as a god.
He returned and attacked Edenia with a plague of Zombies, but he and his zombies were defeated in "Albert Wesker Returns"In his final appearance in Albert Wesker's Final Bout, It revealed he murdered Ethan's parents Hugh and Diane Tidwell, who worked for the Umbrella and served Ozwell E. Spencer. He faced Ethan for the last time, but he transformed with the Uroborus Virus and was killed by Vegethan.
lbert Wesker is power-hungry, cunning and manipulative and seeks power and dominance over everything. He is a Machiavellian schemer, constantly plotting to achieve his own goals and everything he does is meant to serve his purposes. Wesker works constantly behind the scenes, often using others to do his dirty work for him. He maintains a calm and collected manner most of the time and is always looking to payback anyone who wrongs him. Wesker is able to manipulate others to work for him, but doesn't care for anyone except himself. He believes that he is destined to be the god of a new world, one that he would create by purifying it.
Thanks to his injecting himself with that experimental virus, Wesker has superhuman strenth, reflexes, speed, and agility and seems to take great pleasure in demonstrating his power so as to intimidate his foes. Wesker's speed and reflexes are perhaps his most notable abilities since they allow him to dodge bullets at almost point blank range, perform short dashes of speed faster than the brain could comprehend, giving him the appearance of teleporting, and leap great heights. Wesker's strength is so much so that he can throw large missiles with one hand, lift steel girders off his body, and kill a chimera B.O.W. with one strike. However, his own serum proves to be his biggest weakness, as overdoses of it weaken him significantly.
The injection also resulted in his developing of a rapid healing factor that, when combined with his great endurance, makes him almost invincible. A rocket exploding in his hands only incapacitated Wesker for a moment, thousands of pounds of steel falling on him from a few stories dazed him for a few seconds, and he quickly healed from his face getting hideously burned.
Despite Wesker mainly relying on his physical abilities, he is a skilled gunman from his days as a S.T.A.R.S. member and keeps his Samurai Edge pistol holstered with him at all times, since Wesker never, never, lets his guard down.
