In Villian terms, what if Operation Overdrive serves to "connect" the previous Power Ranger shows from Ninja Storm to Mystic Force? With so many villians in Boukenger it may be possible especially the Jaryuu & Dark Shadow. Think it it all works like this.
Villians 2: The remants of Mesogog's research.
* Mesogog Jr. (Ryuuwon): Mesogog's "enhanced clone" that asborbed the Dinogem powers as well in the explosion. Attempts to carry his father's "noble work". His Dino Gem power combines the abilties of the DinoThunder Rangers, added with his own "regeneration abiltiy" and "evolution" powers.
"Jaryuu": Though the grunts, the strongest are hand picked to be "evolved"

Villians 3: Somehow, I can expect Lotor somehow escaped his prison in Mesogog's jar and recuited some of his old allies. The Kelzak Furies could be reintroduced.
* Lotor
* "Yaiba": Lotor's new 2nd in command.
* "Shizuka": Replaces Marah & Kapri. Maybe serve in the story as Lotor's estranged daughter.
