Birth! Baron Ashura! - S1.E8

Having summoned Nonakargo in the previous episode, Baron Ashura reveals its true ability - the machine can open up its torso and capture other machines with an electromagnetic net. Currently locked inside is Aphrodai A, the result of their confrontation in episode 7. As Ashura escapes and orders Nonakargo to capture Mazinger Z, Tsubasa tells Yasu to send out "the signal" in the form of a firework. This signal turns out to be the command to summon the Pilder, which was actually hidden underneath the Kurogane house, sending it (and Ankokuji, who fell on top) flying towards Kouji's location. Meanwhile, Boss and his cohorts who were originally planning to steal Mazinger Z decide to flee, since Nonakargo is approaching them. However, they're stopped by a strange new character in a sombrero, who is revealed to be another member of the Kurogane House - the sharpshooter Django.
