Hellmageddon
From the Keroro Wiki
The Hellmageddon (
It can destroy a planet in a matter of seconds. When not destroying a planet, she often uses a scaled-down version of this attack (that can be as small as 1:1 trillion). Sometimes when she sees someone hitting Keroro, she transforms and uses this version of Hellmageddon, which usually catches others, including Keroro, in the blast. Once, she almost used a scaled-up version (100:1) when she was angered.
To execute the attack, she slams the meteorite end of her Lucifer Spear into the ground. The most common reason for her to use the Hellmageddon ability is when someone in any way threatens Keroro.
