List of Rarest BIONICLE Sets

This is a list of BIONICLE sets considered the rarest. This is based on numerous factors, including their original status as limited edition sets, or their current availability/prominence on sites such as eBay and Bricklink.

Original Tohunga Sets
All six original Matoran, including 1388 Huki, 1389 Onepu, 1390 Maku, 1391 Jala, 1392 Kongu and 1393 Matoro, are generally harder to find two decades later - especially complete sets with their respective disks. Originally retailed for free as promotional sets, currently sell for around US $15 and up on eBay and Bricklink. Certain colored limbs and masks may be harder to come by.

8539 Manas
454 pieces, contains two Manas crabs. Originally retailed for US $89.99, currently sells for US $130 and up on eBay and Bricklink. Does not contain any notable rare parts.

630 pieces, contains Cahdok and Gahdok. Originally retailed for US $59.99, currently sells for US $80 and up on eBay and Bricklink. Rare pieces include part #43093, which the set has 22 of in white. It appears in hundreds of sets in blue, and this is one of three LEGO sets to feature it in white.

10201 Takutanuva
399 pieces, exclusive combiner of Takanuva and Makuta, contains "Takutanuva". Originally retailed for US $49.99, currently sells for US $100 and up on eBay and Bricklink. The set is identical to 3287 Takutanuva, except it includes a rare movie edition of the Kanohi Kraahkan, which on its own sells for US $30 and up on eBay and Bricklink.

10202 Ultimate Dume
555 pieces, exclusive combiner of Nidhiki, Krekka, Dume and Nivawk, contains Ultimate Dume. Originally retailed for US $49.99, currently sells for US $70 and up on eBay and Bricklink.

132 pieces, exclusive combiner of Thok, Vezok and Reidak, contains Irnakk. Originally retailed for US $24.99, currently sells for US $50 and up on eBay and Bricklink. Rare pieces include Irnakk's gold spine.

8923 Hydraxon
165 pieces, contains Hydraxon. The set's exclusivity is up for debate; it originally retailed for US $19.99, but it currently sells for around US $50 and up on eBay and Bricklink. It was never a limited edition set. Rare pieces include the gray shark tooth blade (part #57567), and Hydraxon's mask can be hard to come by.

Rarest Sets
Based on their prices, 8935 Nocturn, 8940 Karzahni, 8953 Icarax and 8998 Toa Mata Nui are among the rarest of the sets listed above. Compared to their original retail prices, these sets are currently sold for three times their original worth. Other sets, like the limited edition 8942 Jetrax T6, are extremely hard to find in the first place.
