These are awesome! I ordered Ultra Sonic Raider. (because it looked all too much like a motorcycle I entered in a contest, but I lost [disqualified for printing photos on wrong paper/ address on same sheet].)

Ok, Maybe it just inspired it.

But it's awesome anyway.
)All four ninjas in ZX outfits
)Pythor, The Kahuna behind it all! (there once was a fifth tribe, but Pythor Ate them all up) Plus Spitta (Venomari)
)All four Weapons!
)BROWN treads and wheels!

And with these new sets (spinners too) we finally se the rest of the Venomari tribe and the Constrictai tribe!

Nice!
The Ninja are really cool with the newer sets especially. Be sure to add the BF throwing star and fighting claw into the mix of sweet weapons for these guys to deal damage to their enemies.
