They reshot Jake becoming Operation Overdrive instead of Megaforce, from ep2 of Gokaiger, maybe they aren't allowed to become Megaforce within the Super Mode.
The helmets of Megaforce from the intro has been changed to various different ones. Here I capped some. Here is Pink Operation Overdrive, Blue Ninja Storm, Red Time Force, Navy Ranger, Yellow Dino Thunder (which doesn't make sense, Noah becomes Blue Ninja Storm while Emma becomes Navy, not Noah).
Pink Samurai Ranger, Green SPD Ranger, Wild Force Red, Blue SPD, and Yellow SPD.
