Swaplust Persik

This is Persik! He is based off a swapped version of those Black and red things. In Swaplust, he replaces Mettaton and the reason he's not interested in sex is because Persik is 16 and only adults were given the ability to feel lust, Despite being considered a legal adult where he is originally from. And instead of a quiz show he is hired for commercial advertisements.

In the normal Underlust AU, He is the 3rd brother of "Them" and is still not interested in sex for the same reasons. Persik has also like Mettaton but never had the courage to say so. After the rape incident and the fact his brothers almost died, he was distraught and felt bad for his brothers and Mettaton. Now Persik is scared to say that he is a fan of  Mettaton and is terrified to go introduce himself to MTT because he is related to "Them"

Also Persik is sexually attracted to boats because of some weird-ass hentai he saw..
