This is an amazing set! The dragon is very well structured, and incredibly fun (if difficult) to build! The inner workings are brilliant, plus... EPIC TOESIES!

Pros

• Colors
• Joints
• Posable toes
• Decorative wings & tail
• Kinda cute

Cons

• Difficult to build
• Always falls over
• Price
• Vezon (Ruins the cuteness effect slightly)

All in all, I say that if you can find one under $150, you should buy it.

Parts:
Vezon&Kardas's parts are same than Axonn's, Brutaka's and Vezon&Fenrakk's, but instructions for other models are not included. Parts give great start for Bionicle building, thought there are also some very unuseable and juniorized parts like ugly Piraka Torsos. They still work well in Kardas. Amout of useful limb pieces is nice, including Vahki legs, Piraka legs, Rahkshi legs and Metrutoran legs. There is also many feet, some weapons, some armours and some small, but extremely useful TECHNIC parts, including six lovely ball joint with axle holes. Many Bohrok eyes are nice too. 9.5/10

Desing:
Vezon is nearbly same than one from Vezon&Fenrakk. Only differences are arms. Armour is bit different and other arm has shield instead. Fusion Staff isn't as cool as before, but it's just a minor con.
Kardas, in his case, is awesome. He's big, sturdy, quite poseable and has some interesting tehcniques. Jaws snaps, wings can be spread and Vezon can ride his favourite dragon. Even toes are poseable. Kardas looks very good on a shelf. 9.5/10

Building:
Building 10204 is mainly easy and fun, but Kardas's head is difficult. I suppose that there is error in instruction manual, because some pins doesn't fit insede the skull like manual says. It can be done in another way, so it really isn´t so bad thing.
Vezon has still pretty boring body build. 9/10

Playability:
Vezon is basic action figure with 12 points of articulation. Fun to play with. Kardas may be even too big for fast play, but he's sturdy. Kardas is fun to put different poses, so it's funny overall. Kids will love this set. 9/10

Price:
Price of 10204 is about 50€, so brick-per-part ratio is pretty good. For example, Axonn and Brutaka both cost 25€ and Vezon&Fenrakk costs about 40€. That's 90€, so 50€ is nearbly 50% off. Very good price, really worth of it.
10/10

Final points: 4.7/5. So it have deserved five out of five.

this set will complete any collection, it will be the best in any collection to.
