First, get the right costume. Look for a bright yellow Pikachu onesie or make one yourself with yellow fabric and black accents for the ears, tail, and markings. Then, focus on the face. You can use yellow face paint to complete the look. Don't forget about Pikachu's rosy cheeks, which can be added with a bit of pink blush. Also, practice Pikachu's cute poses and expressions, like its shocked face or its happy hopping pose. This will make your cosplay more engaging and fun.
If the cosplayer traveled through the anime novels that they cosplayed, they might find some unexpected plots. For example, they might encounter their own characters and communicate with them. Or they might discover that something different was happening to their characters than they knew. In short, this kind of plot might surprise and excite them.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
Cosplay is a form of art and self - expression. The idea of an 'erotic groped story' goes against the very essence of cosplay. Cosplayers put in a lot of effort into their costumes and portrayals, and the community promotes a friendly and safe environment. Such inappropriate stories are not in line with the values of the cosplay community which emphasizes respect for others, creativity, and enjoyment of fictional characters in a positive way.
One way is to check on popular fanfiction websites. Look for ones with high ratings and a lot of reviews. For example, Archive of Our Own (AO3) has a large collection of AOT fanfictions. You can search for the most popular ones there.
A common theme is loyalty. Given their comradeship in the series, fanfictions often explore how their loyalty to each other extends beyond just being fellow soldiers. Another theme could be sacrifice, as they are in a dangerous world where they might have to sacrifice for one another.
One common theme is loyalty. Pieck is often depicted as being loyal to her comrades and her cause. Another theme is sacrifice, as she is in a situation where she may have to give up a lot for the greater good.
Love and romance are also likely themes. Writers may depict the development of romantic feelings between Yelena and Pieck. This could involve slow - burn romances where they gradually realize their feelings for each other, or perhaps more fast - paced love stories where they fall in love quickly due to some extraordinary circumstances. There could also be themes of sacrifice, where one of them is willing to sacrifice something for the other in the context of their relationship.
