Synopsis[edit | edit source]


Gadess has used the Gyandlar mothership to devastate the largest city on the planet[1]. At the ruins of the neighbouring Emerald City Rom, Pro Truck Racer, Triple Jim, Combat Buggy, Rom Stol, Blue Jet and Rod Drill oversee the arrival of casualties via Land Giant 32. Rom, Jet and Drill wonder what exactly to do about the Gyandlar. Further away Leina is watching the arrivals with Fire Robo and Kempō Robo when they spot something falling out of the sky near the Gyandlar ship and set off to investigate - the fire has burned enough of the forest to reveal an old ruin. They go underground to investigate but the incident has also alerted Garudi, who runs into the patrolling Blackbird Robo. Both are damaged in a brief fight but Garudi parachutes out of his shuttle and lands right on top of the ruins. His shuttle crashes nearby, causing part of the underground building to collapse on Leina and her friends. The next morning Garudi wakes to find Rom, Jet, Drill, Pro Truck Racer and Combat Buggy searching for the missing trio; they find Garudi's crashed ship and begin to investigate. Leina and Fire Robo wake up unharmed while Kempō Robo has found a mysterious helmet and an altar that is a representation of Water, related to a legend of the creator's reappearance on Cronos and indicating it is the Dragon Helmet, one of the four elements of the Hyribead. Above the injured Garudi takes shelter in a cave and contacts Diondra for rescue.


Instead of reporting his problem, Diondra tells Gadess she doesn't know where Garudi is and suggests firing a missile into the forest to take out Rom and his friends - but Gadess sees through her jealous plotting, and refuses to destroy his valuable warrior. Rom's search party finds the injured Blackbird Robo, who tells them of his fight the previous night with Garudi. Leina's group meanwhile make their way to the surface only to find themselves emerging in the same cave Garudi is using as a shelter. He is fascinated by the helmet Kempō Robo is wearing and attacks but any wounds he causes the Machine Robo magically heal. Meanwhile Diondra has reluctantly set out on a rescue mission in the Varigale-X to find Garudi; Rom, Jet, Drill and Pro Truck Racer spot the huge force and attack. Garudi manages to knock the helmet off Kempō Robo and take it for himself before Rom finds the trio and battles Garudi. Diondra then attacks with missiles anyway; Pro Truck Racer helps Rom's friends escape but he is worried about the fate of the injured Garudi, who stands laughing as the missile hits. Enraged at the destruction of the altar, Kempō Robo rushes back into the forest but is soon crippled by the missile's effects - Rom changes to Baikanfu and is able to dissipate the after-effects of the warhead. Kempō Robo finds the helmet unharmed, but unknown to them Garudi has also survived, and swears vengeance against Diondra.

Featured characters[edit | edit source]

(Numbers indicate order of appearance.)

Notes[edit | edit source]

  • This is the first appearance of Kempō Robo. Bizarrely, given the large role he has here, it would also be his only appearance in Revenge of Cronos.
  • Rom is also given a Blazer Cannon. Jet's can attach to his jet mode as well as his robot form, which is inaccurate to the toyline as the backpacks could only be attached to non-transforming versions of the character.
  • The destroyed neighbouring city was populated by Rock People; no particular types are seen, most being generics using composite models loosely based on Battle Rock with red/blue colour schemes.
