Here's Fearog
Here's Ransik with Unknown Mutants
Here's new footage of the Rangers with their Chrono Blasters (even though Wes called 'em "Time Blasters.")
They ended up removing pretty much all ground Sentai footage of Fearog except for the up-close smoking shot of him after he recovers from the Rangers' Blasters' attacks.
The shot of Circuit in the Clock Tower calling for the zords is new footage.
However all remaining monster and zord footage is Sentai.

Sentai footage comes from Time Episode 4
