Edward Whelan was raised in a seemingly average and well-off family home. However, his father was secretly abusive of Edward, and this colored his opinion of himself growing up. Edward's self-loathing brought on by the abuse eventually led him to a life on the streets. At some point, he was picked up off the streets by Baron Zemo, the son of a Nazi scientist, and Arnim Zola, the master Nazi geneticist, and subjected to a process that bestowed upon him various ratlike traits and attributes.
