Mishima Zaibatsu's orbital laser satellite is a weapon of mass destruction created by Doctor Abel.
The death-ray is first seen in Tekken 2, Jack-2's ending. It appears again in Gun Jack's ending in Tekken 3, where it is revealed to be made and used by Doctor Abel.
In Tekken 7, Heihachi Mishima orders the satellite to fire at G Corporation HQ, which destroys the whole building. However, Kazuya Mishima survives due to his demonic nature, as does Akuma.
The satellite is later destroyed by Kazuya's Devil Blaster.
