I imagined how New Omnitrix(a.k.a Omniverse Omnitrix) would look like if it was a human girl.
Since it almost never gives Ben an alien he wants, I thought she'd be an unpredictable, impish girl who loves to confuse Ben. But when Ben is in a real trouble, she genuinely tries to help him. Unlike Ben believes, she doesn't hate him. It's just that she thinks it's fun to see him flustered.
