That's right, I have all the Inika now!
I got Jaller, Hewkii, Nuparu, and Hahli on Saturday and they were amazing! Their light up weapons are easily 3 times better than the Piraka's eyes (and those were pretty cool to begin with), they're practically deadly with their rapidfire ability, and despite what other people think, they're masks are some of the coolest yet. I liked them so much that I even made a video review (which should show up in the Official Review Topic some time tomorrow). Today, Matoro and Kongu went off backorder and so I got and built them, but no review this time- there just wasn't a lot to say.
Overall, I think that Nuparu is my favourite; it just doesn't get better than claws and shoulder-Zamor.
