Valgeness is the third Meteokaiju that Kosei obtains. Valgeness has the power to control natural phenomena, and attacks by manipulating elements such as fire, water, wind, and earth. It possesses an exceptionally high level of energy compared to the other Meteokaiju.

Similarly to the Rekiness Armor and Trigaron Armor, Valgeness can transform into the Valgeness Armor, which Omega can equip and fight with.
Valgeness can also transform into a long, spear-like weapon with an integrated axe, the Valgeness Halberd, becoming a source of power for Omega and allowing him to unleash various special moves using different elements.
