"Onua is a fantastic set with some great functions. The new gear function works extremely well with Onua's two-handed hammer. His stud shooter works great and is well incorporated to the hammer. The ammo is easy to lose, but you get extra, so you don't have to worry too much about it. Not only is this my favourite set of this wave of Bionicle, but it is also one of my favourite Bionicle sets of all time! Would recommend this to any Bionicle fan! Be sure to get Terak Creature of Earth as well for a nice combination."
