Darkseid then invades Mars and destroys most of the Martians. Jonzz, however,  is able to escape the planet using a Boom Tube. He travels to the dwarf planet of Eris, thinking that every Martian has died. Ma'alefa'ek, however, is alive and goes to the planet of New Mars in another galaxy to begin a new race of Martians.
