Amy Rose
Amy Rose is a Sonic character created in 1993, making her first appearance in the game Sonic CD. She serves as the self-proclaimed love-interest of Sonic the Hedgehog. In fleshing out the world of Sonichu, Christian Weston Chandler quickly ripped off the character to serve as Sonichu's girlfriend, Rosechu.
Influence on Rosechu
While Sonichu is essentially a recolor of Sonic the Hedgehog with a Pikachu tail shoved up his ass, Chris couldn't even be bothered to employ that tiny amount of creativity in creating Rosechu. Like Amy Rose, Rosechu has green eyes and pink fur, with the spines on her head arranged to resemble a bob haircut. Both wear red boots and dresses, with Rosechu's having a blue trim in a slightly different pattern to Amy's white trim. Visually, the only obvious distinction between the two is the Raichu tail Rosechu has, and the spines on the center of Amy's forehead, which Rosechu lacks. It should be noted, however, that when Chris draws Amy, he fails to draw the forehead spines properly, so he probably left them off Rosechu for the sake of convenience rather than any feeble attempt at innovation.
“ | MAJOR Differences between Amy and Rosie; Amy never had spikes on her back, the clothes are Different; Rosie’s Headband is White, not Red, and Rosechu has a modern girl kinda attitude, and lucky for her, Sonichu RARELY runs away from her charms. And, of course, she has her Electric-Type Attacks to boot. | ” |
Christian Weston Chandler, damning himself with faint praise |
As Christian points out, the only real difference between Amy and Rosechu in terms of characterization is that while Amy's crush on Sonic is not reciprocated, Sonichu has been sucking face with Rosechu since the day they met. Obviously, this hardly marks a difference in their personality. If anything, it says more about the differences between Sonic and Sonichu, since they respond differently to affection. At minimum, by using a different dynamic betwen Sonichu and Rosechu, Chris at least forces himself to steer clear of ripping off Amy Rose's storyline as well as her appearance and character. Since she's already made her romantic conquest, Rosechu is free to pursue the life of a "modern girl", which apparently means face-raping people and producing amateur pornography.
Appearance in Sonichu
As an epilogue to the Sonichu/Sonic team-up in Sonichu 1, Rosechu happens to meet Amy in a chance encounter at CWCville Mall. With no hint of irony, the two remark upon how similar they are, and engage in a vapid conversation about shopping and relationships.
