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.
Definitely. The comic version of Homelander is portrayed as having greater strength and capabilities. This is evident in his confrontations and the scale of his power displays throughout the comic series.
