Zazzka
From Tardis Wiki, the free Doctor Who reference
Commander Zazzka was the Kastrian who, on the orders of King Rokon, detonated the obliteration module containing Eldrad. Zazzka was initially reluctant to carry out the order, since it was given before Eldrad was in position for total destruction, but since the barriers protecting Kastria were rapidly failing, he had no choice but to do so.
