His character could develop in a darker direction. The Venom symbiote often brings out the worst in its hosts. So Harry might become more aggressive and self - centered. He could start to view his friends as obstacles and become more isolated.
One idea could be that Harry Osborn, in his search for power to overcome his family's legacy of misfortune, somehow comes into contact with the Venom symbiote. Maybe he initially tries to control it for his own gain, like using it to take over Oscorp. Another plot could involve Venom influencing Harry's darker side, causing him to clash with Spider - Man in new and unexpected ways.
The 'Venom vs Carnage Graphic Novel' is a must - read for fans of the characters. Venom, originally a villain, has evolved into more of an anti - hero. Carnage, on the other hand, is pure evil. Their clashes in the graphic novel are filled with high - energy action. The narrative also explores the origin and nature of their symbiotic relationships, which is really interesting. It's a great piece of work that shows the complex relationship between these two powerful and menacing characters.
One of the best is 'The Alien Costume' saga. It introduced Venom in a very impactful way. The concept of the symbiote attaching to Spider - Man and then later to Eddie Brock was really cool. It explored Spider - Man's struggle with the new powers and the darker side of the symbiote. It also set up the long - running feud between Spiderman and Venom.
