Kopaka

Kopaka is the Toa/Master of ice on Okoto.

Lego.com description
Kopaka is noble and reserved. Upholding his own strict moral code he strives to be perfect and always "do the right thing". A fact that often makes him appear formal and even cold in the eyes of others. Luckily Kopaka's clumsiness and his not too solid direction sense help the other heroes remember that, after all, Kopaka is just a Toa like them.

History
At an unknown time Kopaka crashed on Okoto.
