I really do love the overall design of this set, so much so that I'd say Onua's new 2016 form has definitely replaced Ekimu as my new favorite constraction set to come out since Gen 1 Bionicle. The color scheme seems much cleaner than his 2015 form now that he isn't decked out in multiple types of purple, and deciding to go with just metallic gold instead of both gold and silver completely eliminates the main problem I had with his prior form. (which was otherwise my favorite of the 2015 Toa sets) The trans purple really does look beautiful now that it's displayed more prominently than it used to be, and I like how even the studs are cast in it now compared to the solid purple ones that came with the Protector of Earth. Although as much as I love his colors, I will admit that there are some choices made about them that I can't help but raise an eyebrow at. The most obvious of which, as noted by others, would be the asymmetric colors for his upper arms. I do understand why they went with having different connectors for each arm, (stability and all that) but if they weren't going to use another trans purple connector, then couldn't they have chosen a less obvious color to use than bluish grey? The other two problems, the use of trans clear for the crystal armor instead of trans purple and the silver color of his feet, are relatively minor nitpicks to me so I don't really mind them very much. I think they really nailed it with his overall build. Onua seems to have just the right amount of 'lean, but sturdy' compared to the other Uniters, with Tahu being (ironically enough) too bulky because of the new gold armor he's sporting, and the three smaller Uniters all either look too oddly proportioned or too skinny for the new torso piece. I think Kopaka looks fine) Onua's new form might not have the squat and sturdy look I liked so much about his Master form, but because of the Bohrok eyes that help fill in his torso and his having larger feet compared to the other Toa, I think he still looks every bit as strong as his 2015 self did. Now for his new mask, at first glance I'd say it isn't recognizable as being an upgrade to the Gen 2 Pakari he sported in his last form, but once you take a moment to really compare the two side by side you'll begin to notice that the similarities are indeed there. So once you throw that nice metallic silver into the mix, I'd say it's a fine evolution to his old mask. (although I can't say I care much for the way the trans purple and gold version looks) Now I especially love his new drill hammer, as it really reminds me of the trick weapons from Bloodborne. I like to imagine that the trans purple studs are actually a special type of explosive charge that Onua can set off to give extra force to his drill swings and to make his hammer swings have an explosive impact against whatever unfortunate bad guy happens to be near him at the time. It's like someone took a warhammer, a giant drill, and a revolver, threw them all into a blender, and served it with a bit of pile bunker sprinkled on top for good measure, everything about that result screams 'ludicrously implausible videogame/anime weapon' and I absolutely love it! However, there are some definite problems I have with it, such as how I don't care for the way that the head swivels at the point where it connects to Onua's hand and how you can't spin the drill without firing the stud launcher. Now for the main problem I have with this set, the Unite Mode. I'm really disappointed to learn that Terak's head just kind of hovers over Onua's with no way to lock it in place, and the added bulk Terak's claws and feet give to Onua's shoulders and waist make the whole thing look like a mess to me. Luckily I like Terak enough as his own set to get him regardless, but after seeing how the Unite Mode gimmick actually works in practice, I don't think I'm going to be getting any of the other Creatures with the exception of Ikir. (he's just such a cute little lava falcon that I can't not get)
