Differences between Hyakujuu Gattai GaoKing and the Wild Force Megazord

Hyakujuu Gattai GaoKing 	Wild Force Megazord
Was joined by the mecha of many previous Sentai Ranger teams and infused with their power in order to battle Lost Highness Rakushaasa in Hyakujuu Sentai Gaoranger vs. Super Sentai. 	Did not take part in "Forever Red".
In Ninpu Sentai Hurricaneger vs. Gaoranger, it fought alongside several Hurricaneger mecha, and two of its usual components and GaoElephant fused together with Karakuri Giant Gourai Senpuujin. 	Never fought alongside the Ninja Storm Rangers' mecha, and none of its components ever took part in the formation of the Thunderstorm Megazord.
GaoKing fought in the mecha battle of Gokaiger Goseiger Super Sentai 199 Hero Great Battle, where it joined Ohranger Robo and Change Robo in battling Buredoran of the Chupacabra before contributing its power to help destroy Black Cross Colossus.	Wild Force Megazord did not take part in "Legendary Battle", though the Red Lion Wildzord did aid the Megaforce Rangers in their prior engagement with The Armada. It also never fought alongside the Zeo Megazord or against Vrak, while Change Robo and Black Cross Colossus have never been adapted into Power Rangers.
Had several additional combinations involving additional Power Animals conceptualized but never employed in the series. 	As a result of GaoKing's additional formations never appearing on screen, they were never introduced into Power Rangers Wild Force.
In Tokumei Sentai Go-Busters vs. Kaizoku Sentai Gokaiger: The Movie, Go-Buster Lioh used the power of the Phantom Ranger Keys to transform into GaoKing. 	
The Grid Battler's third robo will most likely not become the Wild Force Megazord, even if they do team up with the Mega Rangers.
