With the threat of Dark Specter looming over the Power Rangers Universe, the heroes have been pushed to dangerous extremes in the hopes of saving their future. In fact, some of the worst villains of all time have also joined in the fight for survival, including Lord Drakkon. While this is certainly shocking on its own, the fact that any hero in the entire Multiverse would sacrifice themselves for him is even more so, especially when that hero just so happens to be one of the greatest Rangers of all time.
