Somehow when Brook, Nikki, John and Wendy landed in Mobius, Nikki starts to fall in love with Sonic, but is too shy to adimit. Sonic discovered it and feels the same way Nikki feels, shy... In Sonic X: New Adventure, Avalon turns Nikki to the dark side, but Sonic made her come back by admiting his feelings to her and kiss her, turning her into a hedgehog and normal again. (In the game series, Sonic still hasn't admit his love for Nikki)
