Ninja was a robot from the United Kingdom which competed in Season 1.5, the debut of This is Fighting Robots. Although it was not initially selected by any of the celebrity team captains, it was chosen by Sa Beining during its preliminary battle against 008, Saturn and Xiake, securing its place in the tournament as part of the Yellow team.

Ninja with Paul Streeter

Ninja is a 'axlebot', driven by two large tires at either side of the robot similar in design to former Battlebots competitor OverKill. It was armed with a large sword, which swung overhead courtesy of the robot's drive power, and a wedge which enabled it to get underneath, push and attack other robots using the sword. As a axlebot, Ninja is also invertible. The robot lacks a weapon motor, which means that it cannot attack from a standstill, and needs to reverse, or halt on a forward drive in order to deliver a blow.

Saturn vs 008 vs Ninja

Ninja was not initially chosen by the celebrities in their initial selection process, and was required to fight in a four-way rumble in order to impress the celebrities. There, it faced 008, Saturn and Xiake, in a battle which was only partially shown in Episode 2. In the aforementioned highlights, Ninja was initially seen to push Xiake across the arena, at the same time that 008 had its wheel ripped off by Saturn. However, it was unable to land any significant attacks on its remaining opponents, despite coming close to striking Saturn as the British machine drove up its wedge. Ninja continued to dodge and mistime its attacks throughout the battle; however, its aggressive display impressed Sa Beining, who chose it to become part of the Yellow team. As a result, Ninja's place in the main competition was secured.

Ninja vs Bonfire

As part of the Yellow team, Ninja fought fellow British machines in Bonfire and Griffin Mk II, alongside the American Blue. Ninja initially fought Bonfire, and landed an overhead blow on Griffin Mk II, following this up with a lighter hit. Ninja was later forced to abandon its private battle with Griffin Mk II to target the immobile Bonfire, which Blue was relentlessly attacking. Ninja followed suit, and landed several attacks on the motionless Bonfire before leaving the beaten machine. Griffin Mk II came in to hold Blue in place, and Ninja landed an overhead hit on Blue. Ninja and Griffin Mk II collaborated to push Blue back, ultimately resulting in Griffin Mk II's immobilization under an arena hammer.

Ninja vs Blue

With only Ninja and Blue active, both robots attempted to strike each other from above, but largely missed. After narrowly missing an attack on Ninja, Blue turned itself over when retracting its weapon. Ninja pushed Blue back, managing to prevent it from self-righting, but became stuck on the ramrods. The momentum of Ninja's push sent Blue sliding back, where it could freely self-right. Ninja continued to pin Blue against the wall, and Blue missed with its retaliating strikes. In the final ten seconds of the battle, Ninja drove under Blue, which climbed even further up the body of Ninja by swinging its weapon, but Ninja pushed Blue towards the Grinder, before the battle concluded. The episode was left on a cliffhanger, which was resolved in Episode 4; the subsequent Judges' decision went against Ninja, ultimately resulting in Sa Beining losing the first round of the competition to Green team captain Zheng Shaung, despite being tied on three points each.
