At first, Tempest's power consisted only of Goblins and Fanged Wolves, whose originally swore loyalty to Rimuru. However, after the Ogres joined and evolved into Oni, Tempest's military was able to confidently challenged 200.000 Orc forces head on. After their defeats, some of the Orcs and Gabil's Lizardmen also joined Tempest, thus effectively increase Tempest's military might.
