History YMMV / MetalHeroes

* CriticProof: ''Series/BRoboKabutack'' and ''Series/TetsuwanTanteiRobotack'' get bashed a lot for the "kiddy" direction they went in, but while it's CommonKnowledge that they killed the franchise, they actually scored higher ratings than the three seasons that preceded them.

** ''Series/JikuuSenshiSpielban'': [[GodSaveUsFromTheQueen Queen Pandora]] is the true ruler of the [[PlanetLooters Waller Empire]], using their supposed deity Waller as a means of keeping her subordinates in line through fear. Driven [[ItsAllAboutMe purely by a desire to sustain her own life]], Pandora ravaged numerous planets for their resources, including Spielban and Diana's homeworld of Clin. Seeking the genius of Clin biologist Doctor Ben for her own ends, Pandora forcibly converts him into [[EvilGenius Doctor Bio]] and later makes him [[UnwillingRoboticization roboticize]] his own daughter into the cyborg assassin Hellvira. Her other subordinates fare little better under her rule; she tricks Shadow, Gasher and Deathzero into going on suicide missions and petrifies Rikki into a throne to sit on as punishment for questioning her.
** ''Series/ChoujinkiMetalder'': [[BigBad God Neros]], also known as Gozo Kirihara and formerly Kunio Muraki, is a truly vile EvilOverlord bent on imposing his twisted will on the world. Originally dismissed from the Metalder project and allowed to be imprisoned in Singapore, he escaped thanks to bribery and changed his face via plastic surgery, building up an empire using stolen mob funds, which masqueraded as a legitimate charity. In order to TakeOverTheWorld, Neros focused on mass starvation imposed on whole nations, along with the [[KillAllHumans genocide of humanity]]; Neros even murdered his former partner Dr. Koga, who had protested against using Metalder for evil purposes. After Shingo Ōgi discovers his secret identity, he brainwashes the man to kill Metalder. When this fails, he plans to blow up his own lair, with most of his minions inside, while he escapes disguised as his lieutenant. When this succeeded, he murdered Metalder's ally Topgunder to torment Ryusei. Having no limits to depravity, Neros tried to force Metalder to do evil, and [[MindRape mentally tortured]] him before trying to finish him off.
** ''Series/KidouKeijiJiban'': [[MadScientist Doctor Giba]] is the cruel leader of [[NebulousEvilOrganization Bioron]] who seeks to use biochemistry to [[TakeOverTheWorld conquer the world]]. Originally a being born from a chemical spill, Giba saw his nature as proof of humanity's evil and sought to subjugate them in return. To this end, Giba sent his Bioron agents to kidnap dozens of humans to experiment on, including Naoto's parents and little sister. When Jiban opposes him, Giba kidnaps his child companion Mayumi and turns her into an unwilling suicide bomber to kill Jiban. After his agents destroy Jiban, Giba wages an all-out attack on Japan, leveling entire city blocks and attacking people with killer bees carrying a HatePlague. Giba is even cruel to his own minions, killing his assistants Marsha and Karsha in cold blood for failing to die against Jiban. In the finale, Giba uses Mayumi as a HumanShield against Jiban before attempting to bombard every country in the world with his missiles out of spite.
** ''Series/JuukouBFighter'': [[BadBoss Emperor Gaohm]] is a [[VileVillainSaccharineShow surprisingly monstrous villain in a rather lighthearted toku]]. Coming to Earth after conquering and enslaving people in several dimensions, Gaohm seeks to [[OmnicidalManiac kill all life on the planet]], so he can harness the power of [[ButterflyOfDeathAndRebirth Saint Papilia]] when she tries to undo his actions and [[ImmortalityImmorality use her to become immortal]]. To gather energy for his plan, Gaohm sacrifices his minions Gigaro and Schwartz, and later tricks Hidra into becoming an unwitting suicide bomber to kill the B-Fighters.

** ''Series/JuukouBFighter'': [[BigBad Emperor Gaohm]] is a [[VileVillainSaccharineShow surprisingly monstrous villain in a rather lighthearted toku]]. Gaohm [[BadBoss treats his people as disposable pawns]], even equipping one of his minions with a suicide bomb, while costing many other minions their lives. Gaohm seeks nothing less than genocide of multiple dimensions, and any who aren't killed will simply be enslaved. He has a predilection for taking children of the worlds he attacks and transporting them to be used for slave labor. When pushed too far, he simply decides to [[OmnicidalManiac kill everything on Earth]] until the B-Fighters stop him.
