Despite being mostly a Merchandise-Driven kids' show depicting about happy kids playing spinning tops, Metal Fight Beyblade has some moments that was truly terrifying to watch and witness. Some characters also tend to induce these themselves.
Metal Fusion/Metal Fight
- Reiji. Let's do a list, shall we? He enjoys tormenting his opponents, even after he's clearly already won the battle (during his battle with Hyoma, for example, where we see Poison Serpent actually wrapping itself around Hyoma's neck in a way that would make someone think of strangulation), he has no qualms about scaring the everloving crap out of little kids and he talks like a snake going after it prey. His eyes are also usually hidden and, when they open, he looks outright insane!
- Yu being betrayed by Dark Nebula. The kid only lost one time and he was forced to battle Reiji, who stuck to his usual routine of tormenting his opponent. Made even worse when Yu spotted Ryuga watching him and begged him to help, only for Ryuga to turn and walk away from him, showing that the person he thought was a good friend was only using him, shredding the last bit of hope he had for anyone to help him. He manages to escape but, when he appears before Gingka and his friends, he looks completely battered and passes out immediately after he finds them, as if he's just then finally reached the limit of his energy. He's then captured again and left in a dark room, just being forced to wait for whatever punishment might be coming to him.
- The end of Kyoya's fight against Ryuga in episode 49, in which we see the possessed Ryuga for the first time. It ends with Kyoya's crushing defeat and him being Impaled with Extreme Prejudice by L-Drago itself.
- Adding onto this, the dark power itself. It continuously gained more and more power inside of Ryuga's body until it completely took control of his body and made him take on the appearance of a demonic, dragon-like creature.
- For whatever reason, after gaining Dark Bull, Benkei seemingly goes utterly insane with power. He begins hallucinating Gingka and starts screaming the word "Bull" over and over again. Even with the comedy of his English voice, it's still unsettling to watch in action.
Metal Masters/Baku
- Continuing on the subject of the dark power, we learn a lot about it in this season when it's discovered that it's infected Tsubasa, bringing out a darkness in his heart that we eventually learn about through flashbacks. Tsubasa's dark side was just completely insane and only wanted to win, no matter what. This lead to the destruction of the entire arena during his and Yu's battle against Demure and Benkei, as well as knocking out both of them, AND Yu. It makes one wonder why he never told anyone the truth about his past.
- Then, later on, we learn the origin of the dark power: It was the dark emotions in the hearts of the people that L-Drago was passed down to through the centuries, including greed, ambitions, anger, and desires of those people. Think about it: a power actually created by the darkness in peoples' hearts...
- There's also the nightmare Yu had after the above mentioned battle. A little kid, especially a normally happy one like Yu, dreaming of an entire building going up in flames while he can only stand there and watch. You wouldn't imagine such graphic imagery from the mind of a kid like him.
- Julius' ghastly
◊ expression◊ after he crosses his Despair Event Horizon when he lost against Damian. The way it's drawn is just downright terrifying. - Any battle involving Damian can qualify as this, especially when Hades Gate is used. Getting dragged down into a gate that leads into a world that is the Beyblade equivalent of Hell itself? Good god.
- Adding to that, Damian is also ready to get Kerbecs to beat you up with chains used as whips whenever you do or say something funny to him.
- Something scarier? Beyblade Hell can also blast infernos to burn you up, as Kyoya found out first hand. Worse, they can appear on whatever spot you are standing. Being burned by an inferno is no joke!
- The Arrangement in general. Depending on whether your genetics are 100% compatible with it or not, which only Jack, Damian and Toby have proven to be, going through the process can be VERY painful. Almost all the people put through the Arrangement suffer terrible physical and mental damage, destroying their blading careers for good as well as leaving them with severe physical/mental trauma and rendering them cripples for the rest of their lives! Even for those that are 100% compatible, the Arrangement brings out, aside from enhanced beyblading skills, intensified negative emotions and in the cases of Jack and Damian, possible insanity. It even turns a Nice Guy like Zeo into someone who is loaded with hatred, and he wasn't even fully compatible with the Arrangement. Jack ended up becoming more than willing to casually turn people and their beys into works of art drawn with what might as well be a chainsaw. Then there's Damian, who spent several years in the highest level of Arrangement to the point where his original personality was almost certainly erased entirely, turning him into someone whose entire purpose of existence is essentially to carry out the will of Dr. Ziggurat, not to mention the sheer levels of sadism that came with it as Julian Konzern can testify. And let's not even start on what it did to Toby.
- The potential of Twisted Tempo and the Spiral Force. A small discharge was enough to annihilate an entire landscape including a lake, forest and mountain. And if Ziggurat wasn't lying, a meltdown of it could destroy the entire planet. If Masamune, Gingka and co. hadn't stopped Faust and Twisted Tempo, it would have been The End of the World as We Know It.
- The fact that Twisted Tempo can create black holes and drag people into alternate universes with its space-warping ability. If that's not enough, it is shown what happens to those trapped inside the black holes: stuck in a timeless grey-scale void for eternity. THAT is the terrifying ability of a Beyblade with Reality Warper powers. The fact that Faust and Tempo's abilities are based on real life science possibly makes it even more terrifying.
Metal Fury/4D
- A minor detail in the long run, but a group of tomb robbers who had been tailing Ryuto actually threatened him with knives! In this world where most people use magical spinning tops as a way of settling their disputes, it is at least a bit frightening to see actual deadly weapons being used.
- Rago's line to Kenta in Episode 148 more or less qualifies as this, where he threatened to kill him. You know it is a nightmare fuel when a villain attempts to straight-up murder a hero in a mostly Merchandise-Driven kids show.
- Rago: It's fine. If you really want to die that badly, let me finish you first.
- The entire story of Metal Fury is basically centered around the Apocalypse and, when everything's said and done, the destruction caused during the final battle isn't just magically fixed: it stays around for, presumably, many years after.
- And this battle affected the entire world: volcanoes erupted, earthquakes ensued, buildings were destroyed, etc. Also, some people died...This IS a kids' show, right?!
