Venom's character in the comics is a bit ambiguous. He has moments where he aligns with heroic causes, but often his actions are driven by his own agenda and aren't purely good.
Not really. Venom has had complex character arcs and isn't strictly a bad guy. Sometimes he acts against heroes, but his motives and actions can be ambiguous.
The Marvel superhero Venom was not a bad person. Venom is part of the superhero symbiotic in Marvel Comics. It comes from an alien race with various abilities and characteristics. Although the venom has some shortcomings such as it sometimes causes harm to humans, it is usually righteous and often acts with its host, Spiderman, to protect the earth.
Well, the plot could involve the Venom symbiote OC trying to protect a small town from a group of villains. Maybe there's a big bad corporation that's polluting the environment and the symbiote OC uses its powers to stop them. It could also form an unlikely alliance with some local heroes.
It could develop powers through exposure to different types of energy. For example, if it gets hit by a blast of gamma radiation, it might gain the ability to turn invisible or something similar.
Venom was often seen as good in the comics. He had a unique appeal and added depth to the comic universe. But some might have different opinions based on their expectations and interpretation.
Sure. There are. One interesting aspect in some 'Harry is Venom' fanfics could be how Harry's magical abilities interact with the Venom symbiote's powers. For example, the symbiote might enhance his magic in unexpected ways or cause some conflicts due to its own nature. You might find some really creative takes on this idea in different fanfics.
The 2018 Venom comic is pretty good. It has interesting character developments and some cool action scenes. However, it might not be for everyone. You should give it a read and decide for yourself.
