The Scenario
Greater Sci-Fi combatant
Actually, the Manga is officially recognized as canon. But, no, I'm not not using it. This is mostly Metroid Prime series stuff. Scan data directly from the games. I got quotes.
"The VOLT DRIVER draws energy from the planetary electromagnetic field and converts it into multi-terawatt bursts of HIGHVOLTAGE." A terawatt is is 1 trillion watts and 3 terawatts is enough to power the entire United States for a year (all of human civilization uses 15 terawatts a year.) So yeah, Samus is pulling out that kind of energy for a basic weapon.
"The JUDICATOR is powered by cold-fusion synthesis. It fires SUPERCOOLED PLASMA at temperatures approaching absolute zero." Absolute Zero is the coldest state imaginable. It's impossible to reach without breaking physics and freezing all of reality. Just getting close causes quantum effects I'd need a physicist to explain. It's roughly -459.67 degrees Fahrenhiet.
"The BATTLEHAMMER is powered by a miniature nuclear reactor. This HEAVY-DUTY repeater is recommended only for those familiar with high-caliber weaponry." Not much to say for this one. It's a rapid fire mini nuke.
"The MAGMAUL, powered by a hyperstatic hydrogen core, fires cohesive projectiles of SUPERHEATED MAGMA." Not much for this one, either. I think I recall hydrogen cores being found in stars, but I'm not positive about that one.
"This proscribed weapon of mass destruction was called an abomination by the ALIMBIC ELDERS because of the harm it could inflict on anyone desperate enough to use it." This the Omega Cannon.
"The Quadraxis went rogue and entered the service of the Ing. Its primary weapon system fires destructive matter-antimatter blasts." This is actually an enemy, not a weapon, but Samus steals that matter-antimatter cannon for use as the Annihilator Beam.
"Warrior Ing are challenging foes. They can render themselves into amorphous puddles and move over most terrain, including walls. Warrior Ing's can turn their bodies into dangerous projectiles sheathed in dark energy. The tips of their legs are razor sharp, making them formidable in melee. Finally, Warrior Ing are capable of channelling transdimensional energy and firing it at their enemies. Their only real weakness is bright, pure light, which they hate and fear." This is another enemy, but I feel I should point out that 'transdimensional' means beyond dimensions. They basically rip a hole in space to attack.
That's pretty much it.
