Bwhaha. A mere robot challenges the great Luca Blight? How sad. X is no match for the mad prince in either power or durability, as Luca possesses as much as his live and death would lead you to believe. X wins his fights by surviving the starting barrage, morphing, getting an extra turn or two from X's heart and then finishing up his foe. He'll have no such luck, requiring a massive amount of WP to put down Luca for the count. He'll be roasted by Flame slashes and deadly sword strikes all the while. Even worse is Luca's triple attacks, making X's Heart boost worthless. Sure, the super fighting robot's a little quicker once he morphs, but that won't nearly be enough to prevent him from being turned to scrap heap by a former godlike champion.
