it's a McToran, released at mcdonalds as a polybag
Takua was never released as a polybag in this form. The cgi promo image is from bionicle.com's character bio page. Biosector01 lists the one time he appeared as a Matoran in 8595 Takua & Pewku. He could be mocced using the pieces from Jala and Nui-Jaga though. Same case with Hahli. She appeared on bionicle.com's bio page but was never officially released as a polybag. Could be mocced using pieces from Maku and Gali.
