Amy Rose is considered Sonic's "girlfriend" (or rather annoying fan) by many in the Sonic fanbase. In her usual appearances, she is always chasing after Sonic or helping out her friends (sometimes both). In SRC, she takes the form of a human due to her appearing in the real world without any memory of how she got here. It can be assumed Chaos Control was used to teleport her to the real world, although this is unknown.
