"It is born intelligent, man-machine one, there is no rival, it is the essence of human wisdom - the nucleus!"
King of Bots website (translated from Chinese)

原子核 (Romanized as yuán zǐ hé and translated as Nuclear Bomb) was a robot from Beijing, China, which competed in the Season 1 of King of Bots. Entered by the Real Steel team – led by Wang Chao, CEO of the Beijing Tiejia Steel Fist Company - it lost its Season 1 battle against Greedy Snake on a Judges’ decision. Regardless, Nuclear Bomb emerged victorious in a nine-robot rumble held at the end of the series, also winning an unaired Tag Team battle.

Nuclear Bomb was succeeded by Wall Breaker in This is Fighting Robots, and The Martian in King of Bots II.


Nuclear Bomb with Team Real Steel

Nuclear Bomb was an invertible, two-wheel drive robot with a two-tone white and black color scheme. Its main weapon was a set of hydraulic horizontal crushing claws at the front, which were intended to grab and crush through opponents. The robot also featured a 20mm titanium wedge at the rear, painted black, intended to be used for pushing and ramming. In addition to this weaponry, Nuclear Bomb was accompanied by a white drone, which was used to provide Team Real Steel with a top-down view of the arena during battles.

The main innovation of Nuclear Bomb was an electromagnetic system used inside the robot, to weigh the robot down when it is being pushed or lifted. This was used successfully to avoid being lifted effectively by Greedy Snake, and also prevented it from being pushed during the nine-robot rumble.

Robot History

King of Bots (Season 1)

Nuclear Bomb competed in Episode 1, where it fought fellow Chinese competitor Greedy Snake in the first round.

Nuclear Bomb is grabbed and thrown over by Greedy Snake

The main robot immediately turned and reversed over a nearby floor flipper, where it lost mobility for several seconds as its accompanying drone hovered overhead. Nuclear Bomb remained immobile on the flipper until Greedy Snake pushed it off while trying to grab it, where it began moving again. However, it stopped driving again in the centre of the arena, with Greedy Snake trying to lift it from the side, but being unable to do so. Eventually, the two robots separated, with Nuclear Bomb still being unable to attack effectively before it was rammed, grabbed and thrown onto its back by Greedy Snake. Nuclear Bomb was pushed, grabbed and lifted again by Greedy Snake, this time being thrown back upright, before Greedy Snake rammed it into the wall spikes. It responded by bumping into Greedy Snake twice, which was unable to turn it over again before time ran out. With both robots still mobile, the battle went to a Judges’ decision, which ruled against Nuclear Bomb, eliminating it from the competition.

Nuclear Bomb also fought in two further battles at the end of the series. The first of which was an unaired Tag Team battle against the American Blue and British multibot The Grubs, where Nuclear Bomb was partnered with Residual Wind. During the battle, Nuclear Bomb's crushers were broken off by Blue, and Residual Wind was also damaged heavily. However, Blue inadvertently immobilized two segments of The Grubs, and as a result, both international robots were counted out, despite Blue still being mobile. Although the producers would later apologize to the international teams, the win by knockout was awarded to Nuclear Bomb and Residual Wind.

"We teamed up with the grubs and fought the carbide clone and the weird in effective horizontal crusher. We exploded the bar on the spinner and caved in their top. The crusher broke off the other bot pretty quickly. In the process we also accidentally squished a grub and pushed one into the screws. The grubs all died and they started counting us out for some reason? Said we lost in a KO despite the other two bots barely moving and Blue still working fine. Producers apologized after for counting us out."

With its crushers fully removed, Nuclear Bomb also fought in a nine-robot Rumble, aired during the last episode of Season 1. There, it fought Blue, Crossfire, Dark Knight, Griffin, Ink Thorns, Steel Dragon, The Grubs and Violent Dragon.

Initially, Nuclear Bomb stayed out of the action, largely remaining close to its starting position as its opponents spread out and attacked each other. It eventually drove to the other side of the arena near the circular saws and was attacked by Blue, with the American machine hammering Nuclear Bomb’s top armor and getting itself beached on top. Nuclear Bomb remained still as an attack from Steel Dragon forced Blue off, and momentarily turned round as Dark Knight pushed Crossfire and Ink Thorns into its right-hand side. Shuffling back and forth, it proceeded to avoid its surviving opponents and the circular saws, before spinning round on the spot twice in the center.

Eventually, Nuclear Bomb pushed the disarmed Crossfire around, and proceeded to push Blue sideways into a now-immobile Chop, The Grubs’ horizontal spinner. Hesitating, it swept Violent Dragon’s detached claw away before driving to the other side of the arena once again, and sat over one of the floor flippers as Blue and Steel Dragon clashed. It maneuvered off the flipper as Dark Knight was left stranded on Griffin’s wing, and helped Steel Dragon push Blue over the floor rods as they raised all three robots off the floor. Nuclear Bomb slipped off the rods almost immediately, and spun round as both of its remaining opponents were left suspended off the floor. As a result, it was declared to have won the Rumble, with Sam Watts of the Grubs team presenting the Real Steel team captain with a piece of Violent Dragon’s head in the post-battle interviews.

Nuclear Bomb II's concept for This is Fighting Robots

Before competing with Wall Breaker, the Real Steel team designed Nuclear Bomb II with which to enter This is Fighting Robots[2]. The new design was armed with a flamethrower in place of the claws, firing out of a large vent in the front of the machine.


  • Despite losing its only battle in the main competition, Nuclear Bomb won both of its battles held as side events.
