Differences between Chouriki Gattai Ohranger Robo and the Zeo Megazord

Choriki Gattai Ohranger Robo 	Zeo Megazord
Was employed to aid the Carrangers in Gekisou Sentai Carranger vs. Ohranger, and may still be active. 	Due to most of the Zeo Rangers becoming the Turbo Rangers and abandoning their previous Zords for the Turbo Megazord, the Zeo Megazord was left dormant.
The red component mecha and Ohranger Robo in its entirety joined in the battle against Lost Highness Rakushaasa during Hyakujuu Sentai Gaoranger vs. Super Sentai. 	Neither the Zeo Megazord nor the Red Ranger's Zord appeared during Forever Red.
All five mecha were debuted on the sixth episode, and did not combine until the following episode. 	All the zords and the Zeo Megazord were debuted together in the third episode.
During Gokaiger Goseiger Super Sentai 199 Hero Great Battle, Ohranger Robo took part in the giant mecha battle and fought Buredoran of the Chupacabra alongside GaoKing and Change Robo, before contributing its power to destroy Black Cross Colossus.	Did not take part in Legendary Battle, and never fought against Vrak in any form or alongside the Wild Force Megazord; neither Change Robo nor Black Cross Colossus have ever been adapted into Power Rangers.
