 It was stolen in the finale by Agent Abrella, but later recovered after Deka Red uses the hidden secondary control system to regain control and then shut down the Deka Base Robo.It is only used when the enemy is too big for Dekaranger Robo, or when the Dekaranger Robo is unavailable, as seen in episode 22, where however it is mentioned that the Deka Base Robo is not as mobile as the Dekaranger Robo to fight a smaller enemy.Deka Base Robo is also suited for providing backup to the other Deka Robos such as in episode 38 as well as destroying regular incoming planetary threats, like the planet destroying missile in episode 30.
