Brocken, The Devil's Revenger

Brocken, The Devil's Revenger is the sixteenth chapter of Mazinger Angels.

Summary
Maria fell asleep during her training so Sakurako gives her a blanket with a proud look on her face. On her next day of training, Maria manages to completely control the holographic Minerva. An emergency alarm then goes off as a Mechanical Beast appears in Tokyo. Honey and Sakurako tell the Angels about information from intelligence agent Annie Texas, who found leads of a large-scale attack being prepared but the time of execution was unknown. Honey and Sakurako were preparing them to fight back against them with remodeled robots and special training. But with the threat happening sooner than expected, something had to be done.

Sakurako offers Maria the use of Proto-Minerva, even though it was only used in simulations. Sakurako then requests that she carry everyone back to Tokyo in order to launch their robots as soon as possible. Sakurako also goes in her own robot, even though her Fire Venus might not be as powerful.

Launching their robots, Maria has Proto-Minerva assume Sirene Mode to fly everyone to Tokyo. The city is being ravaged by Harkenschmitt X9 controlled by Brocken, who is tempting the Angels to come out for another chance of revenge. Fire Venus is dropped onto the city, Sayaka wants Sakurako to hold out until they can get back but Sakurako is not worried. Angered that the Angel team is not present, Brocken has Harkenschmitt attack Fire Venus. Fire Venus manages to destroy the Mechanical Beast's shielded gauntlet and its right arm but is then stuck to a building with adhesives shot from Harkenschmitt's finger. Taunting Fire Venus, Brocken has Harkenschmitt attack Venus with electricity. While Sakurako is in a pinch, she gets Venus' right arm free and the rest of it before going in for a powerful body blow called the Fire Attack which completely destroys Harkenschmitt.

The benefactor from all of the crimes seems amused that the old Fire Venus is being used and that Prof. Nonaka seems to have a plan. The man then proceeds to have his Mechanical Beasts attack Fire Venus as it is cooling down from its attack, pinning it to a building. Sakurako sees the Mechanical Beasts ready for a fight.
