History
UFO Robo Grendizer vs. Great Mazinger:

When Barendos took notice of Kabuto Koji in the TFO taking out the Minifo s he sent to lay destruction to Tokyo and lure out Grendizer, the former immediately ordered Jinjin launched to subdue and capture the latter, at which it was successful. Later, right when Barendos docked into Great Mazinger, he ordered the launch of Jinjin again to pincer-attack Grendizer who just arrived at the robot museum. Jinjin impeded Gerndizer's advance by launching missiles and restraining spazer's wings till Great Mazinger pierced the museum roof and landed outside, immediately launching navel missiles at Grendizer. Soon after, it stroke again, pulling Grendizer back by the neck just as the mech managed to knock off Great Mazinger's Mazinger Blade where Grendizer counters by grabbing its stretchable arms, lying flat on the ground, and applying Hanjuryoku Storm upwards towards it, fully stretching its arms leaving both the stretch tension and gravity outside the beam to pull it down to the ground, immediately destroying it, but giving Great Mazinger the opening it needed to retrieve the blade and start overwhelming Grendizer.
