Here's Gooly Bird.
Here's a shot of MegaYellow kicking Gooly Bird.
Yellow was fighting alone for a bit but then the other 4 joined her.
The 5 of 'em fired their Blasters at the Bird and then Red used his
Battlizer Punch in order to hit the Bird. Gooly Bird fired a blue beam
at MegaYellow and then he retreated. The beam caused their voices to be
switched.
Here's a shot of Gooly Bird with various objects.
He used his switch beam in order to black Black, Pink, Blue and Red's
"Power Weapons" with his objects.
Here's a shot of Gooly Bird with the Astro Axe, Satellite Stunner,
Spiral Saber and Lunar Lance.
He used each weapon on its respective Ranger.
Here's another shot of Gooly Bird with the weapons but this time he has
formed the Quadroblaster but with the Spiral Saber attached to it.
