Destrosaurus was the 22nd Kaiju to appear in the Fireman TV series, been the Monster of the Week in Ep.22, "It has Arrived! Transformed Alien.

_Bio and Abilities_
Destrosaurus was among the few Kaiju to be form in an union of, in this case, four Alien Individuals from Planet Prima, whose motives to come to Earth weren't conquest or Kill Fireman, but to take Earth Culture to their world and become an advance Society as they were primitive; still, their actions were hostile in nature and kidnapped a man and two kids to force SAF to Comply.

In their true form, the Prima Aliens are odd and eccentric with Monkey like attributes and mannerisms despite their Human like aspect, albeit with stretched out faces – this last detail was a camera trick to give a simian like appearance to them. Moreover the Prima were far resilient compare to Humans, as a man hit the Main Prima with a cleaver onto its head, leaving no mark on him; a bit later, the Main Prima is hit with a laser beam, while it stunned him it did not killed him.

Along with been dangerous and mean spirited, the Prima have powers to boot: Such as Radiation Ray that they could fire from the mouth and Hands; Mind Control Powers; Stupid Ray, which was a blue ray that would wrap around a life form and make them act (well) stupid; but their final and truly dangerous card, was to Combine into Destrosaurus itself. The Main Prima wore a blue Robe with yellow golden outlines, where as the 3 Subordinates wore a Red Robe with different Golden Pattern and white pants.

In their Combine form, Destrosaurus was a bipedal Dark grey color lizard, with Red Scaring over its body and Red eyes; it could release radiation from its mouth, as well the standard fire breath practically seen with almost every Fireman Monster thus far. His roar was among the few in the Fireman Kaiju Roster to be unique and not derived from the Gamera Sound Library.

The Destrosaurus suit would be reused for two more Fireman Kaiju: Gadorasaurus and Dark Mander.

# Veteran Actor Senkichi Omura, who plays the Main Alien Prima and Toho Regular, steals the Episode. He is just going all the way with his role with the facial expressions. That's why his image in the pic is most effort I done for a character, compare to the other members of the Prima Team; but really, he and the other 3 guys are just the best thing to watch about this episode.
Which makes it funny that their monster form is a Lizard and not a Monkey.

_History_
A Meteor crashes onto a Wooded Mountain chain and four Eccentric Humanoid Aliens, the Prima, screech and jump around across the land. SAF comes to investigates the incident, noticing signs of Radiation in the area and dead trees.

Elsewhere, a man wandering the woods stumbles upon the Prima and tries to defend himself with a cleaver, doing no harm to the Main Prima; the latter then reacts by using its mind control powers, disarming the man and damaging the cleaver with a Radiation Ray fired from the hands, the man is kidnapped, his screams alerting Misaki and Chiba nearby, but only finding the now Radioactive Cleaver. The Man is put under the influence of the Stupidity Ray, knocking him out, the Prima then kidnapped Two Children, and while Misaki and Chiba try to stop it, the latter is hit by Radiation Ray.

Misaki is then Corner by the Prima, who explain their motives to come to Earth and take the Culture for their primitive one to become a Culture Society, demanding SAF to submit to their demands if he wants to see the kids, the Aliens then escape into the thick brush. The rest of SAF comes to the mountains to provide assistance as well treat Chiba; the SAF members received a Telepathic Message from an unknown Source (Sadly I can't make out what the voice says due to the lack of Subs, also, this part felt random, as the Prima showed no sign to be telepathic), SAF then finds the Meteor.

As Misaki, along with Mizushima, are ambushed by the Prima, the latter escape as the former holds the Aliens, but just before he is about to be killed, the rest of SAF appears, springing an ambushed of their own; feeling cornered, the four Prima combine and transformed into Destrosaurus; as SAF take cover, Misaki takes the Beast's attention from them, then Transform into Fireman for the battle.

Fireman beats and tosses Destrosaurus around, but the beasts uses both its Radiation and then Fire Breath, but the hero avoids it; Fireman then takes the monster down with a kick. Fireman is then pinned down by the monster, but briefly, as he pushes him, grabs it by the legs then tosses it. After a few more hits, Fireman finishes off Destrosaurus by blowing its head off with FireFlash. The two Children celebrating his victory.

After the battle, the Old Man and the Children are return safely home.
