Teddy might try to have a friendly conversation with the Dursleys, but they would probably be hostile.
The Dursleys could be very dismissive of Teddy at first. However, Teddy, being a curious wizard, might keep trying to engage them. He could end up using his magic to do small things around the house to get their attention. Maybe they would start to see him in a different light, or maybe they would be even more afraid. And Teddy would be constantly comparing their behavior to what he knows about how they treated Harry.
Well, Teddy might be shocked by the Dursleys' coldness at first. He could show them some magic in a very subtle way, just to see their reactions.
Well, perhaps Teddy would be shocked by the Dursleys' coldness. Teddy, being a more open - minded wizard, might not understand their narrow - mindedness at first.
Well, Teddy could learn a great deal about his family's history from the members of the Order. Maybe he'd discover some hidden secrets or untold stories.
Well, it could be about Teddy Lupin traveling back in time and meeting his father's friends, the Marauders. Maybe he gets to experience their pranks first - hand and learns some new magical tricks from them.
Obviously, Teddy is one of the main characters. He is likely to be the one driving the story forward with his actions and reactions.
Well, one possibility is that Teddy, being the son of Remus Lupin, would likely be filled with a sense of justice. He might immediately be on guard around Umbridge. Since Umbridge was known for her cruel and unjust ways at Hogwarts. Teddy could use his Metamorphmagus abilities to play tricks on her, like changing his appearance to something that scares her when she's being particularly mean.
In this kind of fanfiction, perhaps Teddy Lupin discovers a magical way to time - travel and meets his father. It could show Teddy learning about his father's character and values through their interactions. Maybe his father teaches him some unique magic that was passed down in the family.
Pinkie Pie and Sonic could have a really fun interaction. Pinkie Pie is all about having a good time and making friends. She would probably be super excited to meet Sonic and might throw a big party in his honor. Sonic, who is used to action - packed situations, might find Pinkie Pie's energy and enthusiasm a bit overwhelming but also endearing.
A more complex interaction could be when they face a moral dilemma. For example, Superman has his strict code of not killing, while Robin, having grown up in the darker world of Gotham, might be more inclined towards harsher methods at times. This could lead to some intense discussions between them. But in the end, they could learn from each other. Superman could show Robin that there are always alternatives to violence, and Robin could teach Superman about the importance of being adaptable in different situations.
It could be a rogue Death Eater who escaped justice and is now seeking revenge on the Order and anyone related to them. So, Teddy, being Lupin's son, would be a target.
