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.
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 super power often seen in such fanfiction is elemental manipulation. A character could have the power to control all four elements - fire, water, earth, and air - with great precision. They might be able to create huge firestorms to fend off dark wizards or summon tsunamis within the Hogwarts lake. There are also super strength powers where a wizard or witch can lift extremely heavy objects, like the entire Hogwarts castle, which comes in handy during battles against powerful dark forces. And of course, there's the power of invisibility without the need for an invisibility cloak, which gives a character an edge in spying or sneaking around.
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.

He could gather information without being detected, giving Batman and him an edge in their fight against evil.
When it comes to super powers in Harry Potter fanfiction, they often disrupt the original storylines in various ways. Consider a power like telekinesis. If a character has this power, they can manipulate objects from a distance. This could change how the Triwizard Tournament tasks are completed. Instead of using magic in the traditional ways shown in the original story, they could use telekinesis to move things around. Also, if a character has the power of mind control, they can influence the actions of other characters, including the main characters like Harry. This can lead to a completely different set of actions and reactions, ultimately changing the whole direction of the story.
