S3 E1 • Alerte évasion ! (partie 1)

There is a jailbreak at the maximum security prison of Hero Factory! Criminals like the crazed Toxic Reapa, the evil Jawblade and the schizophrenic Splitface have broken free and are spreading chaos and destruction all across the galaxy! It is revealed that the villainous Black Phantom is behind the prison break, and that it was merely a distraction for the heroes, so he could attempt to destroy Hero Factory's Assembly Tower while they were recapturing the escapees. Evo, Surge and Furno are sent on missions to catch and cuff the villains, while Rocka remains at Hero Factory to stop Black Phantom, who already has the mission managers neutralized, and destroy his Arachnix pet.
