Ben's Greatest Enemy Returns
Vilgax resurfaces with a new army. Under the Galactic Code of Conduct, he challenges the greatest champion of each world he visits to single combat, the prize being that champion's planet. Each time he defeats a champion, he absorbs their powers, the tenth and latest being Ultimo of the Galactic Enforcers. With the strength of ten heroes at his disposal, Vilgax heads to Earth and challenges Ben, giving him 24 hours to prepare.
