     Referring now to FIG. 5 of the drawing a battery pack is generally represented by reference numeral 17 and is characterized by a battery housing 18, which receives and encloses a rectangular-shaped conventional battery 30. The receptacle housing 18 is further characterized by a front panel 19, a pair of parallel side panels 20, a rear panel 16 and a bottom panel (not illustrated). A closure panel 21 is secured to the rear panel 16 by means of a hinge 29 and a male connector 23 and female connector 23 are attached to the underside of the closure panel 21 in spaced relationship. The male connector 23 is designed to removably attach to the positive terminal 32 and the female connector 22 to the negative terminal 31, of the battery 30 when the closure panel 21 is closed over the battery 30. A length of electrical wiring 15 extends from the electric motor in the motor housing 2 of the power unit 1 to the battery 30 in the battery pack 17 for powering the power unit 1, as hereinafter described. A pair of top straps 24 extend from the upper portion of the side panels 20 and a pair of bottom straps 26 extend from the bottom portion of the side panels 20, as illustrated. Fastening elements of the loop-pile fasteners 25 are attached to the top straps 24 and the bottom straps 26. Accordingly, the loop elements 25a, secured to the top straps 24 and the pile elements 25b, secured to the bottom straps 26, are joined, respectively, when the top straps 24 and bottom straps 26 are crossed over the chest of the figure toy 34, in order to removably secure the battery pack 17 to the back of the figure toy 34, as illustrated in FIG. 1. It is understood that other attachment devices such as pegs, bands, belts, snaps, wires, in non-exclusive particular can also be employed to secure the battery pack 17 to the figure toy 34. 
     Referring now to FIGS. 5-7 of the drawing and to FIG. 6 in particular, a rotary switch 36 is secured to the rear panel 16 of the battery housing 18 for supplying power to the power unit 1 through the electrical wiring 15. One end of the electrical wiring 15 is wired into the rotary switch 36 and to the male connector 23 and the female connector 23, located in the closure panel 21 and the other end is either wired directly into the windings of the electric motor (not illustrated) located in the motor housing 2 or to the pressure switch 28, which pressure switch 28 is wired into the windings of the electric motor. Referring to FIG. 7 of the drawing, in an alternative embodiment, a fixed switch 27 is provided in optional cooperation with a motor activation switch 33 in the battery housing 18, to enable continuous electrical transmission to the electric motor (not illustrated) located in the motor housing 2, while selective energizing of the electric motor is enabled by opening and closing of the electric circuit by operation of the motor activation switch 33.

In a third alternative embodiment the pressure switch 28 located in the motor housing 2 can be wired directly from the electrical wiring 15 into the windings of the electric motor to facilitate operation of the electric motor by pressing the pressure switch 28. 
     Referring again to FIG. 1 of the drawing, when the power unit and battery pack for toys of this invention is used, the power unit 1 is first mounted in the right hand 35 of the figure toy 34 by closing the fingers 35a around the bottom handle 5. The battery pack 17 is then strapped to the back of the figure toy 34 by lapping the top straps 24 and the bottom straps 26 across the chest of the figure toy 34 and securing the respective loop elements 25a to the companion pile elements 25b. Referring again to FIG. 6 of the drawing, under circumstances where the battery housing 18 of the battery pack 17 is fitted with the rotary switch 36 illustrated in FIG. 6, the rotary switch 36 can be first manipulated to the &#34;on&#34; position, to enable operation of the electric motor (not illustrated) inside the motor housing 2 of the power unit 1 by manipulating the pressure switch 28 to the &#34;on&#34; position. Alternatively, as illustrated in FIG. 7, if the battery pack 17 is fitted with the combination fixed switch 27 and motor activation switch 33, the motor activation switch 33 can be initially slidably manipulated to the &#34;on&#34; position to enable operation of the electric motor in the power unit 1 by manipulating the fixed switch 27 provided in the battery housing 18 to the &#34;on&#34;  position. Further in the alternative, under circumstances where the pressure switch 28 is wired directly into the motor windings from the electrical wiring 15, the electric motor is operated by pressing the pressure switch 28. Furthermore, it will be recognized that the pressure switch 28 can be located on the battery pack 17 in place of the rotary switch 36. 
     An accessory such as the rubber or plastic blade 4 can be attached to the motor housing 2 by aligning the blade shaft 3 of the blade 4 with the tip opening 13 located in the stabilizer tip 12 of the accessory stabilizer cap 11 and inserting the blade shaft 3 into the adaptor opening 10 provided in the projecting end of the shaft adaptor 8. The opposite end of the shaft adaptor 8 is secured to the motor shaft (not illustrated) attached to the electric motor located in the motor housing 2, as heretofore described. Accordingly, activation of either the pressure switch 28, the motor activation switch 33, the fixed switch 27 or the rotary switch 36 where a rotary switch is utilized, in the desired combinations then causes the blade 4 to rotate responsive to operation of the electric motor. Various other accessories such as fans and other accessories known to those skilled in the art can be utilized in connection with the power unit 1. 
     It will be appreciated by those skilled in the art that the power unit 1 can be held by the figure toy 34 in a number of different ways, depending upon the provision of the bottom handle 5 illustrated in FIG. 2, the top handle 6 illustrated in FIG. 3 or the pair of side handles 7 illustrated in FIG. 4. Accordingly, the power unit 1 can be held with one or both hands of the figure toy 34, depending upon the choice of the power unit 1, the particular function desired and the accessory used with the power unit 1. 
     It is understood that while the battery pack 17 is illustrated with a single battery 30 provided therein, the battery housing 18 can be enlarged and shaped to receive additional batteries 30, without departing from the spirit and scope of the invention. Furthermore, the battery pack 17 can be adapted to contain alternative electrical power sources such as solar cells, chemical sources and like energy sources, in non-exclusive particular, and while the figure toy 34 is illustrated as a futuristic figure which is the product of space-age motion pictures, other conventional figures such as the &#34;GI-Joe&#34; character and similar figure toys and characters can be used to implement the power unit and battery pack of this invention. 
     Referring again to FIGS. 1-4 of the drawing it is further understood that the accessory stabilizer cap 11 can be alternatively permanently mounted on the motor housing 2 under circumstances where it is constructed of heavy wire material to facilitate coupling of the blade shaft 4 to the shaft adaptor 8 with the accessory stabilizer in place. 
     While the preferred embodiments of the invention have been described above it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
