Sonic the Hedgehog - Sonic! Catch Madonna!!

Madonna the human was a character that had the purpose of being the supposed love interest to the Blue Blur: Sonic the Hedgehog in early production of the franchise, this idea was discarded quickly and only some pixel model and concpt art exist of her.

Only for Sonic the hedgehog (2006) to make the same mistake, but worse due to him being way younger than her, dead, next to another love interest and somehow worse written than if the game had no dialogue at all.
