Amy is the first friend Sonic met through his adventures, after he saved her from his robotic doppelgänger Metal Sonic, she fell in love with him, and, usually out of coincidence, ended up participating in his adventures alongside the others. Once she found out about his suppossed death, she quickly joined the Resistance, becoming its voice, since, aside from fighting like usual, she is the one that keeps the entire Resistance updated and communicated, often acting as a navigator in missions where she isn't required to fight.
