Another of my son's contributions to "Digimon Empire," these guys serve as cannonfodder villains during part the obligatory "travelling the Digital World" segment of my story when Trailmon's train-tracks take the heroes to a city under siege by armies of these guys.
Their leader, Saturnmon, looks like a planet-version of Saucermon, but when the heroes go Ultimate and attack him, knocking him back to Saucermon level, a Black Card turns him into the Mega-level virus-type, NovaSolarmon...leaving the heroes with the dilemma of how to fight a malevolent, sentient sun before the entire Digital World goes up in flames.
I think I'll ditch the walker legs on Alimon, though, just have them fly around in that egg-cup thing like the beginning credits of "The Jetsons."
