Little did you know you'd go from this to mastering Omega Flowey ;) GL on your Geno Photomega Flowey project! Take all the time you need, and take care of yourself, alright? :)
To anyone thinking these are from Banana man, do yourself a favor and just put them side by side. Pay attention to where the shadows are, and the makeup. They are similar but definitely not the same images.
I think if Flowey absorbed ASGORE's soul, he would appear as the real Asriel because he has a soul again, or maybe he wouldn't have the same design as Omega Flowey.
