One of the wierdest romances, perhaps ever, is Sonic the Hedgehog and Princess Elise in the 2006 game.
It was always wrote off as bestiality, bad and disgusting. But to be honest...what were the developers actually thinking with this....and what does Sonic and the other characters think about Elise and her affection for Sonic?
Sonic has a different reaction than to Amy, the other romantic interrest. Unlike Amy, Sonic isn't annoyed at Elise or writes her off, but stays stoic and nice the whole time. Does Sonic feel sorry for her? Elise to me, always seemed rather sickly and mentally confused. Sonic, and other characters know this, perhaps. That's why Amy is ok with Elise kissing Sonic, and Sonic doesn't mind blowing out the flame to erase time. Because Elise is in a bad situation mentally.
To me, she works rather well as a stand-in for the Sonic fanbase at that time, like Sonic-Man.
