Astromons (アストロモンス Asutoromons) is a plant-reptilian kaiju and a RP character used by Gallibon the Destroyer.


Astromons is constantly hungry and is very, very violent in battle, going as so far as willing to eat his opponents. Brutal and unpredictable, there's no telling what Astromons can do in combat.


Debut: Ultra Kaiju Battle Royale

Astromons along with Snowgon and Femigon were led into battle with Dorobon to fight against the other four Ultra monsters Gomora, Red King, Eleking and Antlar at Hokkaido. Astromons was the second monster to appear there, disguised as the Tigris Flower before then spraying knock out gas and then rising up, revealing his true monster form.

Astromons began his attack by attacking Eleking, wielding up his hook hand and then slashing it against Eleking. Eleking then moved to his side and then wrapped his tail around Astromons, sending volts of electricity against Astromons, shocking him. Astromons then sprayed his acidic mist at Eleking's area, causing Eleking to stagger away from him. Astromons then swung his hook arm against Eleking then staggered back in case.

Eleking retaliated by firing light blades at Astromons, causing Astromons to flail around. Astromons and Femigon then regrouped with each other to better combat against both Antlar and Eleking. Astromons and Femigon then fired both of their fireballs and acidic mist towards Antlar and Eleking, only for Antlar to retaliate by firing a big energy blast against the two, causing a big explosion to occur in front of Astromons and Femigon.

Astromons then got back up and then ran towards Gomora and Antlar, swinging his hook arm around like a madman. Antlar then bit on Astromons's hook arm, causing Astromons pain. Astromons then lashed out his whip arm against Gomora's face. Gomora was hit, but reacted by lashing out his own tail against Astromons. Then from out of the blue; then came Ultraman Joneus appeared to deal with the Ultra monster situation. Ultraman Joneus took quick notice of Astromons and then blasted his Planium Beam against him, causing Astromons to stagger back.

Astromons then activated his flower gorge and then ran up to both Gomora and Ultraman Joneus. Ultraman Joneus dived at Astromons, punching at him hard; sending Astromons flying back. As Femigon, Dorobon and Snowgon then all left retreating, Astromons was the last member of his team still standing; Astromons then got up and went ballistic and attacking EX Red King, who he was not scared of. However, Astromons was no match for EX Red King who in bit down on Astromons's shoulder and tore it off.

Astromons slashed his hook hand down across EX Red King's chest, causing EX Red King great pain. EX Red King then punched against Astromons's chest, creating a big impact and sending Astromons flying against Ultraman Joneus. Ultraman Jonues then grabbed Astromons and then used his Boomerang Guillotine against him; causing Astromons to stagger back. Finally, Ultraman Joneus used his Planium Beam against Astromons, creating a big explosion. Astromons then got up and flew away, retreating.
