On Homeworld Royal fugitives are fleeing their pursuers, followers of the mass uprising against the ruling order but this is no normal revolution. The rebellion has been fostered by blackmail by the Baron Kaza who offers the people of the Microverse immortality but only on one condition, they obey him as ruler.
Immortality via the science of the body banks is a great temptation to give u one's freedom especially if entertainment in the form of gladiatorial combat is the main release for this new civilisation. The Royals and their supporters opposed this barbarism and are now in danger as they are gradually hunted down.
Their world has been ruled by Baron Karza for a thousand years and as an ancient explorer returns from the stars and Commander Rann finds all has been in vain since warp drive has been invented in the years of his absence and Homeworld has conquered, enslaved and ravaged many alien worlds and civilisations.
Coming together in the arena the central characters of our story Commander Rann, Mrionette (the Princess in disguise), Bug, Acroyear and Biotron make good their escape to the edges of their universe and escape through the space-wall.....with a little help from the enigmatic Time Traveller.
Arriving on an unknown world they soon discover how small they are in comparison to the inhabitants of earth as they confront a monster or dog as we would know the creature and tangle with a lawn mower. It's not long before the now permanently breached space-wall allows Baron Karzas Battle cruisers through and the lad doing the gardening becomes the ally of our heroes.
Escaping they leave a wrecked back garden with a teenager wondering how to explain what just happened.
At long last I am now aware of the background of the toys turned comic book characters by Marvel. One of two I read back in the seventies, though only a handful of these as Rom was more to may taste but these things were toys and or cartoons like The Transformers and passed me by as a long haired student.
Biotron Toy (Souce Wiki: Fair Use)
The Micronauts were made by by Mego from 1976 to 1980 and I actually don't recall seeing these things. Seems the comic outlasted the toys as they were revived by IDW a few years back. The is particular comic book series lasted 59 issues which is a respectable run and there revivals and team-ups later on. I may well pick up some more of this series.
