History VideoGame / TheSpaceAdventure

* SpellMyNameWithAnS: Crystal Boy's name is spelled like that in the game but the correct spelling would be "Bowie", [[Creator/DavidBowie after the singer]].

* AdaptedOut: The space pirate Sandra is replaced by two antagonists unique to this game, despite her being the final opponent faced by Cobra in the original version of the Royal Sisters arc.

** Hammerbolt Joe fights Cobra in completely different circunstances than in the manga and is blown in half instead of being shot into outer space.
* DropDeadGorgeous: Most of the female villains killed by Cobra are left sprawled on the floor in an alluring way, as in the source material. There's even a FreezeFrameBonus of the brunette cyborg Bomber's bare breast when she's defeated by Cobra... [[FanDisservice before a chunk of her torso blows up]] and she collapses with her butt pointed towards the viewer.

* LongTitle: The actual in-game title is "The Space Adventure: COBRA - The Legendary Bandit".

** Hammerbolt Joe was the villain of a short scenario in the original series. He appears as one of the antagonists here and gets to kill not just a bunch of minor character but also [[spoiler:Jane]] as well. He captures Lady and fights Cobra to the death in a straight fight instead of being a DirtyCoward who tries to hide away while his rocket fists do the job for him.

* GratuitousEnglish: The opening narration was already in english in the original PC Engine CD version, featuring a few mishaps like calling the Psychogun a "pistol-first firearm".

* {{Golem}}: One of the enemies in the final area is the Craggon, a stone man wielding an axe that can [[RollingAttack transform into a boulder]].

* NoSell: Crystal Bowie's polarized glass body can deflect laser beams, including those of the Psychogun.

* AdvancingBossOfDoom: Upon confronting Tarbeige and his powerful attack reflectors, Cobra is forced to retreat, access the morgue and hide on a coffin until he comes close enough. Moving into into the same area as Tarbeige at any point before the morgue just brings up options to either keep running or shoot him -- which results in Cobra blasting himself and resetting the scene.

** [[spoiler:Cobra's final attack against Crystal Bowie, as in the manga.]]

* BigBadWannabe: Vigaro is the actual villainous mastermind after the Ultimate Weapon and he eventually gets it, but he goes down far easier than Crystal Bowie does.

* EvolvingWeapon: The Ultimate Weapon is an one-eyed egg that transforms into any weapon that it spots, including vehicles like tanks and spaceships.

** The game uses videogame mechanics to exaggerate how resilent Cobra is even by the standards of the manga, so in several fights he'll get knocked down over and over but stand back up at full HP every time. He also manages to easily destroy the Ultimate Weapon despite it turning into a spaceship, which was something he pulled all stops to prevent from happening in the original story.

* NotTheFallThatKillsYou: In this version of the story, Jane is mortally wounded when Hammerbolt Joe punches her off a very tall height.

* LivingMcGuffin: The Royal sisters arec hunted by the Pirate Guild for the tattoos on their backs that when combined reveal the location of the Ultimate Weapon.

* AdaptationalBadass: Hammerbolt Joe was the villain of a short scenario in the original series. He appears as one of the antagonists here and gets to kill not just a bunch of minor character but also [[spoiler:Jane]] as well. He captures Lady and fights Cobra to the death in a straight fight instead of being a DirtyCoward who tries to hide away while his rocket fists do the job for him.
