Corwin’s bionicle Tahu, despite his upgrade in the latest Lego marketing campaign, was not sufficiently well armed for Corwin. Mom made the mistake of mentioning that Corwin could use the sword from the non-upgraded Tahu to make his new Tahu more powerful. Corwin couldn’t find the sword but he managed to find weapons from most of the other Toa. This lead to the very heavily armed Tahu seen in this picture.
