Actually the Gigazord you see in that picture is one solid piece unfortunately. It can combine with other zords via the zord builder system but best you'll get is something similar to Gojyu Gokai-oh. Long story short, USELESS!

Since you already have the samurai megazord and that the Gigazord isn't that good either I would say no. If you just want the Bull Megazord out of that I don't see the point.

You're welcome. But honestly, if you can find it at a good price (like say thirty to forty dollars) get it, otherwise pass on it.
