Here's new footage of Thunderon and Falkar
Here's new footage of Falkar and Thunderon
This shot of the Red Ranger appears to be the start of Sentai footage however this specific shot actually is a recycled shot from a previous episode because this shot was not shown in GoGoV Episode 21.
Once you see the Red Ranger touching the top of Falkar then that's when the Sentai footage from GoGoV Episode 21 actually begins.


These shots of the Red Ranger falling down are new footage     The first shot is the start of new footage.

This shot means that it's right back to Sentai footage once again. Hmm, I wonder how many times I'm going to be saying that this time around?
This shot of the 2 morphed female Rangers is the start of new footage. This had to be reshot because GoPink had her visor down for most of this shot however once the scene changes to a shot of Falkar then it's back to Sentai footage.
The footage that Captain Mitchell and Ms. Fairweather are watching on the Rescue Ops' Monitor in regards to the Rangers fighting Thunderon is all Sentai footage.
Once the scene changes and goes back to the battle, it's still Sentai footage.
This shot of the 2 Rangers is the start of new footage.
Once you see a close-up shot of Thunderon's feet, it's back to Sentai footage once again.
All opened visor scenes of the Red and Pink Rangers during the time that they're supposed to be down but they're just playing as if they're unconscious is new footage so they keep on switching back and forth between showing opened visor shots and Sentai footage of Thunderon and Falkar. The shot of the Red and Pink Rangers closing their visors back up is new footage too but it goes back to Sentai footage once you see Thunderon.
This shot of the Red Ranger is new footage which means this is the start of new footage.
This shot of Thunderon and Rangers is back to Sentai footage.
This shot of Falkar is the start of new footage.
This shot of the Demon Card in/on Falkar's back is new footage



These shots   are Sentai footage, the 1st shot is the start of the Sentai footage. The energy effects that you can see in the pics are a result of Diabolico's Demon Card forcing Falkar to grow.
Here's the Max Solarzord Cockpit            
Thunderon didn't actually attack the Max Solarzord in Battle Mode, the footage was edited to make it appear that Thunderon ended up firing at it with its green beam but in GoGoV, it never shot any of its green beams at the Max Solarzord in Battle Mode.
Here's a shot of the Max Solarzord in Battle Mode sparking up I do not know where this footage comes from because it doesn't come from GoGoV Episode 21 but I doubt it's new footage but I will try to keep this shot in mind.
Lightspeed makes it seem like the Max Solarzord in Battle Mode's Shield Lasers are responsible fo destroying Thunderon but in GoGoV, it's actually the Supertrain Megazord's Turbines that destroys him. This shot is actually Sentai footage since it comes from a later episode but I do not recall which 1.

NOTE: All Giant footage is Sentai footage.
NOTE: The Max Solarzord cockpit is an American-made cockpit because it didn't have a cockpit in GoGoV. It didn't have a cockpit because there wasn't a pilot for it in GoGoV.

Sentai info comes from GoGoV Episode 21
