I have seen plenty of SonAmy fanart, and I have seen my fair share of Super Sonic fanart, but this is the first one that both puts them together and captures my attention.
First of all, I'm sure many people may ask, "Why is Amy glowing? She doesn't have a Super transformation!" Well, believe it or not folks, there is a series of hacks for Sonic the Hedgehog, Sonic the Hedgehog 2, and Sonic 3 & Knuckles that replaces Sonic with Classic Amy as a playable character, complete with Piko Piko Hammer AND working Super transformations. Look them up on SonicRetro!
Getting back to the main topic, this artwork takes both a typical pairing and Sonic's signature superpower and weaves them into an otherworldly image that seems to smoothly blend both the mystery and infinity of outer space with (ONLY for this image) the purity and power of true love, which can be seen in how Super Sonic and Super Amy's auras and contrails weave together as they fly away from Mobius. The glare of the sun behind Mobius seems to enhance the overall glowing effect of the image, making both super hedgehogs really shine in this picture.
Long story short: A shiny masterpiece of one of SEGA's most popular pairings, Sonic the Hedgehog and Amy Rose!
