Upgrade

Upgrade, played by Erin Burke, was a pink stylized robot and was one of the original four members. She wore a black dress and cap and was known as the pretty one. As she puts it. Upgrade daydreamed of growing up and becoming a princess or a hover tank. Erin Burke left the band in 2011 due to creative differences and to pursue her acting career. Upgrade is no longer considered to be a canon character in terms of official lore.
