Well, it could be that in certain DC Verse fanfictions, Oliver Queen's abuse of Roy Harper might be more emotional. Maybe Oliver isolates Roy from his friends or makes him feel like he's not good enough by constantly comparing him to others. This can really take a toll on Roy's self - esteem and mental well - being.
One possible reason could be jealousy. If Roy starts to gain more popularity or shows more potential than Oliver expected, Oliver might lash out in an abusive way. Another reason could be a sense of possessiveness. Oliver might see Roy as his protege and want to control every aspect of his development, which could turn into abuse.
In certain comic arcs, Oliver Queen's fate includes his death. But it's important to note that comic storylines can be complex and sometimes characters come back or alternate timelines exist.
One idea could be a story where Oliver Queen finds himself in Kara's universe by some sort of multiverse accident. He teams up with Kara to fight a common enemy that is causing chaos in both their worlds. Their different fighting styles, Oliver's more grounded archery and hand - to - hand combat and Kara's super - powered abilities, would make for an interesting dynamic in battles.
One great 'dark Oliver Queen fanfiction' is 'The Dark Archer's Legacy'. It delves deep into Oliver's darker side, exploring how his experiences on the island could have made him more morally ambiguous. Another is 'Shadows of the Hood', which shows a more ruthless Oliver in his crime - fighting activities, with a lot of complex character development.
Oliver Queen's demise in the comics was a combination of various factors. It involved a final stand against a powerful enemy and his unwavering commitment to justice, leading to his ultimate sacrifice.
