In this fanfiction, Robin might get powers as a result of a genetic mutation triggered by a rare chemical. These powers could include enhanced speed and the ability to see in the dark. He initially hides his powers from the team because he's afraid of how they'll react. But when a dangerous situation arises where his powers could be the key to victory, he reveals them and they all work together to defeat the enemy and accept his new status.
Maybe the main antagonist is an old enemy of Robin's who becomes jealous of his new powers. This enemy then devises a plan to steal Robin's powers or at least neutralize them so that he can regain his former status as the top threat. He could be a powerful martial artist or a criminal mastermind with a large network of henchmen.
One common plotline could be Robin initially struggling to control his new super powers. For example, he might accidentally use his strength and break things around him. Another could be that he has to keep his powers a secret from his friends at first to protect them. And then there could be a villain who is specifically targeting Robin because of his newfound powers.
Often, Robin and Raven are paired in these fanfictions. Raven's dark powers and Robin's new super powers could create an interesting contrast. They might have to team up to fight a common enemy that is attracted to their combined power levels. Additionally, some fanfictions might pair Robin with other DC characters outside of the Teen Titans, like Wonder Woman. She could help Robin understand the greater scope of his powers and how they fit into the DC universe as a whole.
Artemis is also a frequent ally. She and Robin can form a great team, especially if Robin's powers are of a certain nature. For instance, if he has enhanced agility, he can work with Artemis' archery skills to create some amazing combat combinations. And of course, Superboy can be an ally. His super - strength combined with Robin's powers can make for a formidable force against their enemies.
Sure. In fanfiction, the sky's the limit when it comes to giving powers to characters. Batman might be depicted with the power of flight, which would completely change the way he approaches fighting crime. He could swoop down on criminals from above, much like a bat. Robin could have the power of invisibility. This would make him an excellent spy within the criminal underworld. He could gather information without being detected, giving Batman and him an edge in their fight against evil.
Perhaps he gets a power related to mind control. This would allow him to influence the actions of his enemies or even make them fight among themselves. He could also gain a power that lets him absorb the powers of his defeated foes. So, every time he defeats an enemy, he becomes stronger by adding their powers to his own arsenal.
His friends like Batman and Nightwing could be main characters. Batman might use his detective skills to figure out what's wrong with Robin, and Nightwing could be there to offer emotional support.
One good plot could be Robin getting jealous of a new hero in town. This new hero is getting all the media attention and praise from the citizens. Robin starts to feel left out and unappreciated. So, he decides to take on a really difficult mission on his own to prove his worth, which leads to him getting into trouble and having to be rescued by his friends. This shows how his jealousy can lead him astray.
Well, the plot could involve Robin's friends rallying around to take care of him. Maybe they bring him soup and keep him company while he's in bed recovering.
