Their first encounter might be full of tension. Harry, being aware of the name Riddle and its association with Voldemort, would be on guard. Professor Riddle, on the other hand, might be intrigued by Harry's fame. He could approach Harry with a certain air of mystery, perhaps asking him some probing questions about his past and his abilities. Harry would likely respond defensively, creating an immediate sense of unease between them.
One possible plotline could be that Professor Riddle, perhaps a relative of the infamous Voldemort (Tom Riddle), initially has a strained relationship with Harry. He might be suspicious of Harry due to his family connection to the Potters. However, as the story progresses, they could discover they have more in common than they thought, like a shared interest in some arcane magic. And they might end up working together to solve a mystery within Hogwarts that threatens the entire wizarding world.
It could be a very tense encounter. Harry might sense a strong and different kind of power in Bankotsu, and Bankotsu would be baffled by Harry's wand and the spells he can cast. For instance, if Harry uses a spell to defend himself when Bankotsu approaches, Bankotsu would think it was some sort of strange attack and immediately draw his weapon. But then, they might realize that neither of them really wants to fight without proper understanding.
Harry would probably be very defiant at first. He has faced Voldemort (Tom Riddle) before and he won't go down without a fight. He would likely try to use his magic skills to escape or at least hold Tom Riddle off until he can find a way out.
Their first encounter might be really tense. Jake Park would probably be on high alert as soon as he senses Michael Myers' presence. Michael, on the other hand, would just silently approach. Jake might try to run or hide at first, not knowing what Michael's intentions are. It could be a moment of pure fear for Jake as he realizes he's in the presence of a very dangerous being.
At first, it would probably be very difficult. Tom is a complex character with a lot of pride. Harry, on the other hand, has a deep - seated hatred for Voldemort. But as Harry gets to know the young Tom, he might start to see him as a lost child. Their relationship could slowly shift from one of suspicion to a more paternal - like bond as Harry tries to mentor Tom.
In a fanfic, the encounter between Harry Potter and Death could be shown in a more philosophical way. Death could be portrayed as a wise being, not menacing but rather calm. Harry and Death might sit down, like in a dream - like landscape, and have a long conversation about life, death, love, and sacrifice. The scene could be filled with soft light and a gentle breeze, symbolizing the peaceful nature of the discussion despite its heavy topic.
Their first encounter could be really intense. Hades might be sitting on his throne, all imposing, and Will would be a bit scared but also curious. Hades could use his powers to make the area around him seem even more menacing, like making the flames around his throne burn brighter.
One common theme is discovery. Since it's about the first encounter, it often focuses on the characters discovering new things like magic, Hogwarts, or new friends. For example, in many fanfics, Harry's discovery of the wizarding world for the first time is a central theme.
The first encounter might be one of confusion. Percy could be startled to see Artemis suddenly appear in the woods. Artemis, on the other hand, may be trying to figure out why Percy is there. She might question him immediately, and Percy would have to explain his presence, perhaps stuttering a bit as he is in the presence of a major goddess.
Their first encounter could be very tense. Tobirama is a strict and powerful figure, and Naruto might be a bit intimidated at first. But Naruto's natural boldness would soon take over, and he would introduce himself. Tobirama would likely be curious about this strange - looking boy with so much chakra.
