One plot idea could be that the Suicide Squad is sent back in time to prevent a major event that led to the creation of a super - villain they later had to fight. This would give them a chance to change the future for the better. Another idea is that they travel to the future and see the consequences of their actions in the present, and have to find a way to fix things. Or perhaps a member of the Squad accidentally activates a time - travel device and they all end up in different time periods, and have to find each other and get back to their own time.
For Killer Croc, it would be a bit of a struggle. In a more civilized time period, he'd have to hide his appearance and find ways to stay out of sight. But he might also discover new places to hide, like old sewers or caves. El Diablo could use his powers in a more discreet way in different time periods. He might be seen as a sorcerer or something supernatural, which could work to his advantage or get him into trouble. And Captain Boomerang would likely try to steal valuable items from different time periods to make a profit when he gets back, but he'd also have to deal with the different laws and cultures.
A really interesting fanfic is 'Task Force X: New Missions'. In this one, the Suicide Squad gets sent on a series of dangerous and unique missions that test their limits and force them to work together in new ways. It's action - packed and keeps you on the edge of your seat.
One idea for a male OC in a Suicide Squad fanfiction could be a former military sniper. He has a troubled past, having witnessed atrocities during war that led to his dismissal. His skills with a rifle are unmatched, but his mental state is fragile. He's given a second chance in the Suicide Squad. He could have a gruff exterior but a soft heart for those he considers his 'squad mates'.
Yes. But the availability of new Suicide Squad comics can vary. It could be part of a new series, a continuation of an existing one, or a special one-shot. You might need to keep an eye on comic book stores or online platforms for the latest releases.
