History
Bolivar Trask was the owner of Trask Enterprise and also the employer of Richard Parker and Edward Brock Sr. (the fathers of Peter Parker and Eddie Brock Jr. respectively) who they created the sybmiote suit as a cure to cancer project. Though, Trask, from his own agenda, sought to steal and use the basis of the sybmiote suit as a weapon.
Sometime later Trask hired Silver Sable and the Wild Pack to capture Eddie Brock Jr., who became Venom, in obtaining the symbiote suit. After meeting Brock face to face, Trask explains that he wishes for Eddie to test the suit and to learn how to control it. He set Venom on Electro.
Trask entrusted Silver Sable with acquiring vital information on Spider-Man from Eddie, and after Spider-Man's capture, he allowed Adrian Toomes to experiment with Spider-Man to find a way of 'completing' the Suit.
After Eddie gains full control of the Suit, Spider-Man breaks into Trask's office and demands information on Richard Parker. As Trask is about to hand a file over, Venom attacks Trask, who flees to the rooftop helipad in panic. Spider-Man follows Trask, as does Venom. From within the helicpoter, Trask opens fire on Venom, but Venom is unfazed, and he attempts to tip the helicopter off the roof. Only timely intervention from Spider-Man prevented this, although Trask ended up in SHIELD custody, and he was sentenced to several years in prison for his crimes.
Eddie visits Trask in prison, saying that he can't believe that for all Trask did, all he got was three years in a golf course prison. Trask protests that Eddie can't do anything to Trask there, but Eddie transforms into Venom and kills Trask off screen.
