Professor X passed away in the comics due to a powerful attack by a villain who had a vendetta against him. The circumstances were intense and unexpected.
It depends on which specific comic series or storyline you're referring to. In some, Professor X met his demise, but in others, he survived or was brought back to life through various plot devices.
To write a believable Snape, you need to remember his key traits. He's sarcastic, so use lots of biting remarks in his dialogue. For example, when talking to Harry, he could say something like 'Potter, your lack of potion - making skills is only surpassed by your arrogance.'
The interaction could be really interesting. Snape is a complex and often brooding character. The Teletubbies, on the other hand, are all about joy and simplicity. Snape might try to analyze them as he would a magical creature. He might be frustrated by their lack of understanding of his world. However, the Teletubbies' positive attitude could start to affect Snape. They could show him that there's more to life than just the dark arts and his grudges. For example, they might get him to play in their meadow, which would be a completely new experience for him.
There was a time when Professor Snape met a mysterious witch during his travels. She had an air of elegance and mystery that intrigued him. As they spent time together researching ancient spells, he found himself falling for her. However, their different loyalties in the wizarding war put a strain on their relationship. Snape was torn between his love for her and his duties, and in the end, they had to part ways, leaving Snape with a heart full of unrequited love.
Professor X's fate varies in the comics. Sometimes he does die, but comic writers often find ways to bring characters back or explore alternate timelines where his survival is possible.
The relationship could develop through mutual respect for each other's intelligence. Snape respects Hermione's academic prowess and Hermione comes to respect Snape's deep knowledge of magic. For example, in a situation where they are working on a difficult potion together, they start to see each other's strengths.
