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 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.
This is Fighting Robots (Season 1.5)
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.
