High Evolutionary; the clone is nicknamed Allene and is like Doreen in most every way except she is lacking in the restraint and empathy which largely defines Doreen's career as a superhero. Allene strives to create a world where squirrels are the dominant species, sending an army of squirrely into the cloning device to rid them of their restraint and imprisoning every superhero who stands in her way in the Negative Zone. When Doreen gives her last effort to appeal to Allene's humanity, Allene instead banishes Doreen to the moon, where a dying Doreen summons Thor's hammer Mjolnir, becoming Squirrel Thor.
