Death Para-Machine
From Transformers Wiki
The Death Para-Machine (デスパラマシン Desu Paramashin) is a massive space-going weapon. Energy from BlackZarak's stinger is focused and amplified by two massive parabolic dishes at the back of the weapon. From there, the energy is projected forward through twin barrels towards its target. The weapon's main effect is the destruction of ozone, which will spell humanity's doom.

After Devil Z's first plan to destroy all humans failed, BlackZarak - Destroyer from Space it ordered BlackZarak and the Guardminders to begin construction on a massive orbital cannon to destroy Earth's ozone layer as part of Operation M2.
Under BlackZarak's supervision, the Death Para-Machine was assembled in space and prepared to fire. Devil Z sent the Decepticon Godmasters and Headmaster Juniors into space to observe the cannon's firing. The departure of Darkwings and the space jet was detected by Grand Maximus, who alerted the other Autobots, and soon the Autobot Godmasters and Headmaster Juniors were blasting off aboard Maximus to stop them.
When the Autobots arrived, despite fighting bravely, they were too late to stop BlackZarak from firing the Death Para-Machine. A massive energy blast erupted from the cannon and obliterated a chunk of South America; in addition, it caused severe damage to the ozone layer, which resulted in the polar ice caps melting and flooding at the base of the Himalayas.
The first test a success, BlackZarak attempted to fire it a second time, but God Ginrai was able to destroy it using Chōkon Power. A last burst from the exploding weapon struck Grand Maximus, sending the Autobot and the three Headmaster Juniors plunging towards Earth. Crisis! The Day of Human Extinction
