I think I'll fill up an entry all about my feelings on the Piraka...
They were some of the oddest Bionicle characters yet, in my opinion (in case you need a warning, all of the following is my opinion). They have odd light up eyes, glow in the dark teeth, and spines. I really didn't need any of that... but I'm a sucker and I was determined to buy some anyway. I bought based off the weapons, and I only planned to get two or three. After I got Thok, Reidak, and Zaktan, there was a sale (buy 2, get 1 free) that I couldn't pass up, so I grabbed the rest of the Piraka I needed. There were some things I liked about them, and things I didn't. Since nobody's reading this anyway, I'll humor myself by reviewing them all...
Thok: He's probably my favorite one. I got him for the weapon. Excellent ice peg. The gun part is awesome, and while the pick section is a bit odd, it was still nice. It makes a nice, thick, sturdy weapon. Plus, it fits incredibly well in Thok's arm. Then Thok's face is rather good. Not too big, but still large enough to cover up the white head. He looks almost like he has a beard...
The white colouring is a new shade that I don't mind, and the aqua blue (although I was expecting teal like on Kongu) goes well with him. I got him first, and I still like him the best.
Reidak: Note 1: the clawed feet. They don't seem as stable as Thok's large feet, but they look really cool.
Reidak's head is larger than most, and I was disappointed that he really has no "third eye". Oh well, but it makes him feel more like a brute. I thought his saw thing was way too long, and his drill bit seems a little short. It makes a nice weapon, but the proportions are off. His spines were also slightly odd... didn't quite bend right for me, but neither did Thoks. Not my favorite, but he's good.
Zaktan: The secondary colour for the leader is sand green, and while I don't love it, its not too bad. Don't see where I'll use it in a MOC, but whatever... His spines are wacky, his face is kinda long, but they're okay. His weapon is like Reidak's... the blades are too long and the hook is too short, plus it doesn't fit well with the arm (when the blades are out, atleast). Plus, the blades are too thin and flimsy. Can't see them taking a solid blow... Anyway, he’s okay for the Piraka leader.
Hakan: Major disappointment on my part. I wanted him for his cool lava launcher. The weapon looks cool, and works well with the arm, but it is way too small. Not nearly as big and thick as Thok’s, and a major disappointment. The head, likewise, is too small for my liking. Not really big and thick, but just long up and down. Plus, no new colours. Also, his eyes didn't light up very well. Since he's the cool red hero, I'm sure all the little kids used his "light up" features and wasted the batteries before I even got him.
He was one of the Piraka I originally wanted to get, but he was a disappointment to me.
Avak: I was not planning on getting him. I heard once that the Lego Team has been debating releasing brown figures (not sure how accurate that is) and I was thinking I should just buy the brown Piraka to show I support the Po-People. And Avak does have his upsides. His head is pretty nifty, although it doesn't exactly fit on the skull. And when his eyes light up in the dark, he looks really cool. The colours are okay... a new shade of tan plus a chocolate-like brown (that I approve of more than the Metru-brown). But his weapon... lousy in the story and lousy as a set. The thing not only looks bad, but it doesn't fit with his arm at all! I think Lego mis-designed the weapon... if the stud had gone in one other place, then the weapon would've fit nicely on Avak's arm. But the stud is somewhere else, and... ehg. On the bright side, Avak's spines were the easiest to mold around on his back. Yay for that.
Vezok: I really didn't want to get Vezok, and technically, I didn't pay for him either. But I got him in the sale, so he's mine.
The colours are nice... can never have enough dark blue, and the sand blue is a nice addition. The spines and head are okay, but could be better. The weapon looks interesting, but again, I believe it is too small for this animal-like Piraka. Reidak had his huge saw, so why shouldn't Vezok get a large harpoon? It works well by fitting in his arm, but it's still just short!
Anyway, most of the Piraka have their faults. Out of all of them, I liked Thok for his good weapon, head, and general colouring. And that concludes my Piraka review. I now have nothing better to do to waste my time. So you can go on your way no. Thanks for reading. (will not say "sucker" in case you want to read further.
