Mauro is possessed by a huge number of Empty Shadows. They twist his mind, causing him to became an enemy of mankind. Hiro and Luca fight to bring him back.
And you can't save the world 
without the seven legendary cards.
ولا يمكنكم إنقاذ العالم دون
البطاقات السبع الأسطوريّة
Wenn nicht die sieben
legendären Karten vereint sind,
Sans l’ensemble des sept légendaires,
la Terre est condamnée !
Non potete salvare il mondo
senza le sette carte leggendarie.
E vocês não podem salvar o mundo
sem as sete cartas lendárias.
А мир нельзя спасти без всех
семи легендарных карт.
