Here's Wild Weeder and the evil Blue Senturion
Once you see footage of the Evil Senturion on Earth then it's the start of new footage.
Here's Alpha 6, Carlos, Justin and Ashley in the Power Chamber
Here's new footage of kind of a side shot of Lightning Cruiser
Here's new footage of Lightning Cruiser and Storm Blaster with the usual Rangers riding in Storm Blaster whenever Sentai footage of it plays
This shot of Wild Weeder is when it goes back to Sentai footage.
It then cuts to what appears to be new footage of the Blue and Yellow Rangers talking while in Storm Blaster before it cuts back to Sentai footage of Wild Weeder once again.
Once you see the Blue Ranger in midair (after leaving his zord) then it's another start of new footage.
Once it cuts to the Blue Senturion in his cockpit then it's back to Sentai footage.
This shot of Wild Weeder before growing is when it goes back to new footage but as typically usual, once the torpedos hit, it then cuts to a Sentai close-up of Wild Weeder's face while it's turning red and steam (or smoke) is coming out of his mouth while the same thing is happening to his lone Robotic Bee and then they both start to grow.
All Giant footage is Sentai footage.

Sentai footage comes from Car 36
