Brooding being a third party basically came about because he’s the big bad of the Sentai and with the show saving money for the finale, having an original villain as the big bad in every episode was a bit of a cost stretcher.

Also we learn that if a brainwashed Ranger gets morphed, then the brainwashing is undone (at least in this show. The jury’s out for other series).

In terms of personal opinion, have to say a cowardly stage magician is not the most intimidating foe as to warrant a new Megazord formation.
