Lacey's personality is different from that of her original. She is very sneaky and clever whenever Xero disguised as her to foil Baron Vain's evil schemes. She is somewhat athletic, tough, and sarcastic. Unlike Xero, she is really tomboyish and loves to mess with Rat at any oppurtunity. She is also not much of a team player, noting that while she and Rat both were on the same team, "and I'm the team captain ."
