Can the Samurai Gigazord be formed without the auxiliary zords?
 

I know what your first thought probably is: "It's not the samurai gigazord without them". Well, I guess a more accurate question would be can the bullzord, clawzord, and samurai megazord be combined on their own?

Edit: I mean the toys, if that wasn't clear. And now I'm unsure if this is the right section.

The only downside to not having the auxiliary zords is that the chest piece of the bull megazord has no where to go but other than that the three can be combined regardless of whether or not you have the auxiliaries.

Toywise? Sure. It would look almost the same except for the Tiger Drills on the arms, from the front anyway.

So one could survive with the tigerzord and the octozord?

Without the Tigerzord, there's nothing to connect the Beetle and Shark Zords onto the back of the Bullzord

this but It would work.
