Ivy is a young girl who lived on Quarantine after being placed there by her parents, who were concerned by her persistent stories about conversations with plant life.
Ivy displayed high intelligence when examined, but would display anger and hostility when other did not believe her claims about talking with plant life.
While on Quarantine, Ivy developed a close friendship with Kent Shakespeare. Kent was the first to suggest that Ivy does actually communicate with plants, and requested time and funds to study her abilities further.
Ivy was quite upset when Kent started spending more time with the reformed Legion. But after teaming up with some of the other super-powered kids at Quarantine in battle against Grimbor, she told Kent that she was okay now that she had a team of her own to lead.
