|Release date||September 2001|
Set 1389 Onepu was a promotional set released in September 2001 portraying Onepu. It specifically portrays him as he appeared after his diminishment from being inside a Matoran Sphere.
The set was included in McDonald's Happy Meals in September 2001 as one of the six "Tohunga" sets. Each Happy Meal came with one of the six sets, randomly selected. The set consists of eight pieces.
By combining pieces from Onepu with 1388 Huki and 1391 Jala, one can build a Matoran Kaita. Onepu can also be combined with 1388 Huki, 1390 Maku, 1391 Jala, 1392 Kongu, and 1393 Matoro to create a Matoran Nui.
Onepu's arms can be pulled back and released, making them shoot back forward. His right hand is capable of holding a Bamboo Disk, and doing this while he is holding the disk causes him to throw it. The disk could also be stored on his back.
Onepu wears a purple Pakari. Also included is a Bamboo Disk featuring Onua's Kanohi Pakari and the mask's name.
1389 Onepu scored a 64 on Brick Insights, indicating poor reviews. However, consumer reviews contributing to this set's score discuss the aftermarket price, which was not a factor in the original set's release.
