he survived and re-powered up the Roboidz. The series 2 finale had Caleb come face to face with Neuros for the first time. Enraged over her suggestion that she is his true mother, Caleb smashes her on the ground, seemingly killing her, though the post-credit sequence suggested that she may be still alive. Format The episodes all have the same format. The same group of recruits are present for three episodes, during which they are gradually reduced to one. The same challenges are undertaken by all 16 recruits. Day 1 – The four recruits are introduced. They all take on four challenges, two played individually and two played as pairs to try to gain as many bio-rods as they can. Day 2 – The four recruits undertake harder challenges as they try to progress. The final challenge of the day is called 'The Vaporiser', located in V-Lab, and whoever gained the most bio-rods is except from the challenge. The remaining three take part where the losing recruit is vaporised and therefore removed. The remaining three recruits continue to the next day. Day 3 – The remaining three recruits now undertake even tougher challenges. Only one recruit can continue to the final mission. Numbers of bio rods are also re-set from the previous days totals to give everyone an equal chance of progressing to the next stage of the contest. The three of them face The Vaporiser again, and the recruit that reaches the centre first moves onto the final mission. When the four elite recruits have been found they undertake four more harder and different challenges across just one day. After the second and third challenges, two recruits are transported home. The remaining two recruits then face the final challenge in N-Lab, 'The Neuros Web'. Whoever wins the challenge is the crowned the ultimate recruit while the loser is vaporised. The ultimate recruit is then transported home. Characters Caleb Lansing-Gant (Stuart Goldsmith) – Part human, part machine, Caleb is (as far as he knows) the last remaining human on earth. It's later revealed that he is the son of Laura Gant and Simon Lansing, the creators of the Roboidz. He caught an unknown disease at the age of 17 and fell very ill. After his parents gave up on any hope of finding a cure, they cryogenically froze him. After waking up, Caleb has no recollection of his previous life.
