There are several characters who die in Invincible comics. Some major ones include [mention specific characters if applicable]. But it really depends on which story arcs you're referring to.
Percy might become more independent. Without his mom's presence, he has to rely more on himself. He could start to take on more leadership roles within the demigod community.

However, through his experiences and the support of his friends, he gradually learns to balance this new, harsher side with his original kind - hearted nature.
Well, 'invincible mark and eve fanfiction' could cover a wide range of themes. It might explore their relationship in different scenarios.

Mark might use his powers in unique ways to protect Eve, and Eve could use her intelligence to assist Mark.

Another theme is growth. After his mom's death, Percy often has to grow up faster and become more independent.

For example, he may become more decisive in battles or in dealing with other challenges. In some fanfics, there's also the theme of legacy.

One possible plotline could be Percy's journey of grief and how he copes with the loss. He might become more withdrawn at first, then gradually find strength in his friends and his quest.

Maybe he also has to face the fact that his mom's death was part of a larger plan by the villains and he has to stop them from achieving their ultimate goal.
Percy often becomes more somber. He may lose some of his initial naivete. For instance, he might be more cautious in his actions, thinking twice before jumping into a fight like he used to.
There could be a fanfiction titled 'Percy's Struggle After Losing His Mom'. In this, it could show Percy having flashbacks of his mom during battles or difficult times, and how those memories both haunt him and give him the will to keep going. It might also include how he tries to honor his mom's memory in different ways.
