Was stated to be more powerful than the Ninja Megazord
Was used by only one set of rangers: The Kakurangers.
Was piloted by 2 sets of rangers: The Mighty Morphin Power Rangers and the Alien Rangers.
The rangers actually become their mecha instead of piloting them.
The Shogunzords are piloted by the rangers as usual.
Combined form was the avatar of a sentient god and one of the mentors of the Kakurangers.
It displayed the ability to fight autonomously without the Kakurangers.
Combined form was just an inanimate robot without any authority over the Rangers. It did not display any sentience or the ability to fight on its own, but could be remotely controlled from the Ninja Megazord.
Had no ties to the Guardian Beasts from Zyuranger and therefore did not display the ability to combine with King Brachion.
Had the ability to combine with the Falconzord and Titanus to form the Shogun Ultrazord.
