Bannakaffalatta

Bannakaffalatta was a cyborg Zocci aboard the Titanic. He had an accident sometime ago, as a result of which he underwent conversion into a cyborg, for which he experienced some shame. Bannakaffalatta disapproved of shortened versions of his name.

Onboard the Titanic he met the Doctor and briefly strolled around London on Christmas Eve on a tour led by Bayldon Copper. As Bannakaffalatta was small he was able to get through spaces others couldn't. He revealed his cybernetics to Astrid, to whom he took a fancy and asked on a date. (She accepted.) Over a short period of time, he grew to accept his nature as a cyborg. While traveling over the bridge in the Titanic, Bannakaffalatta got across with ease but when the Hosts descended he used his cybernetic body to let out an electromagnetic pulse to destroy them and give the Doctor and the others time to escape. With little power left Bannakaffalatta died. Astrid used his "battery" to destroy furthur Hosts. (DW: Voyage of the Damned)
