Tyssan

Tyssan was a starship enguneer who was serving with earths deep space fleet. He was captured by the Daleks and imprisoned on one of there space ships until fifty slaves including himself were taken down onto Skaro to clear out the mining area were the Daleks were excavating. Tyssan managed to escape two years after his capture. Every time a slave escapes five others are exterminated in his place, as it was with Tyssan. Tyssan managed not to be recaptured and startled Romana as his appearence was mud caked due to a harsh life since his escape. After the Doctor managed to bargin the release o the slaves from the Daleks, Tyssan led them on an attack against the  Movellan's ship. After there easy victory Tyssan led a charge against a group of Daleks sent to destroy the Movellan ship they had taken over. Tyssan joined the charge but it did not do well. Many slaves were exterminated and no Daleks suffered damage. Luckily the Doctor tricked Davros to destroy the Daleks saving Tyssan and the slaves.
