Artificial Sun

The Artificial Sun is a weapon from Space Warrior Baldios and is a super weapon featured in Knights of the Multiverse Season 1. It's a satellite-type weapon that is essentially a flying bomb created by the evil organization L.O.S.R. to melt the North Pole and flood the entire planet.

Abilities
The Artificial Sun's only ability is to generate extremely powerful heat blasts, with the heat rising to temperatures of 4000 degrees (presumably, this power is never seen in the series proper. Thankfully).
