In fanfiction where Snape never betrays Voldemort, how would his relationship with other Death Eaters change?

His relationship with Hermione would be very different. Instead of being friends, they might be enemies at first. Since he was raised by Death Eaters, he might look down on Hermione as a Muggle - born. But as he gets to know her better, he could start to question his beliefs.

Snape could be very cautious in his interactions. He would be constantly aware of the power dynamics. He might flatter the more powerful Death Eaters subtly to avoid suspicion. For instance, he could compliment Bellatrix on her loyalty to the Dark Lord. At the same time, he might try to intimidate the weaker ones to show that he's not to be trifled with. He might use his knowledge of the Dark Arts to his advantage in these interactions, like casually mentioning a difficult spell he's mastered to gain some respect.

In a fanfiction scenario, Harry's actions could cause a complete breakdown in any potential for a positive relationship between them. Snape's loyalty to Dumbledore and his role in protecting Harry from the shadows would be put at risk. Harry would have to face the fact that he may have made a huge mistake. And Snape, who has sacrificed so much already, would be in an even more precarious position, both with Voldemort and in the wizarding world in general. This could lead to a chain of events that completely alters the course of the wizarding war, with far - reaching consequences for both Harry and Snape.

Well, it would be a lot less antagonistic. Without the whole Death Eater past and the spying for Dumbledore while seeming to be on Voldemort's side, Snape wouldn't have that built - up resentment towards Harry. He might actually see Harry as a talented young wizard worthy of proper mentorship, instead of constantly being so harsh on him.

His relationship with Voldemort could change significantly. Voldemort might not immediately perceive Harry as a threat if he looks like a girl. He has a certain image of the boy who will be his downfall, and a girl - like Harry would disrupt that. This could give Harry an opportunity to get closer to Voldemort, perhaps infiltrate his ranks in a way that he couldn't as a boy.

If Snape loses his memory, initially Harry might be very confused. He's used to Snape being his enemy. But without his memories, Snape might not show the same animosity towards Harry. Harry could even feel a sense of pity and try to help Snape regain his memories. Their relationship could shift from one of hatred to a more complex one of trying to understand and help each other.

His Pikachu might feel a bit jealous at first. But eventually, they would all accept Mew as part of the team. Ash would have to spend more time getting to know Mew's unique abilities, which might mean less training time for the others temporarily. However, in the long run, Mew could teach the other Pokemon some new tricks.

The Hogwarts students would be divided. Some would be in disbelief and would still hope that Harry has a good reason for joining. They might secretly support him. Others, especially those who have lost family members to the Death Eaters, would be furious and see Harry as a traitor. Harry's old enemies at Hogwarts, like Draco Malfoy, would also be confused. Draco might initially think that Harry has finally seen the 'right' side, but as he realizes Harry's true intentions (if they are good), he would be conflicted as well since he's been brought up in a Death Eater - influenced family.

His magical education would be very different. Instead of learning at Hogwarts, he might be taught in some dark and secret location by Death Eater instructors. They would likely focus on dark spells and hexes.

It's hard to say exactly. Maybe the kidnapping leads to revelations about Snape's past or uncovers a deeper conspiracy within the Death Eaters. It could also trigger a series of magical battles and strategic escapes.
