The R.O.B. Blaster (ロボットブラスター, Robot Blaster in Japan) is a gray and white member of the R.O.B. Squad. Its color scheme is based on the American version of the Robotic Operating Buddy. The design of the R.O.B. Blaster is almost identical to the R.O.B.Sentry, however they use vastly different fighting styles. Unlike the R.O.B. Sentry, the R.O.B. Blaster fully utilizes its beam firing eyes to attack from a distance, dealing around 19% and medium knockback. There are two varieties of this unit, one which remains stationary, and another that will move around, hovering with its booster rockets. The mobile version can be difficult to battle as it is the fastest member of the R.O.B. Squad, and will attack rapidly from a distance. As with other members of the R.O.B. Squad, these only appear on the Isle of Ancients.
A R.O.B. model boasting robo-beam-blasting eye lenses suited for long-range combat. There are two types--one acts like a stationary gun, sitting in place and lining up targets, and the other is mobile. Actually, the R.O.B. Sentry also features beam-firing capabilities, but because the roles of the R.O.B. Squad are so well defined, there's no conflict between the ranks.
