Suicide bomber

A suicide attack (also known as suicide bombing) was a type of attack in which the attacker expected or intended to die in the process. The Daleks used suicide bombers to destroy a Movellan ship. (TV: Destiny of the Daleks)

A suicide bomber blew himself up in an attempt to kill Jack Harkness. Jack escaped unharmed. Due to the events of Miracle Day, he was still living after the explosion, even after his head was detached. (TV: The New World)

Many robots, such as K9 and the Pain-Maker, were built with a self-destruct function. This usually resulted in an explosion which could allow them to harm targeted lifeforms in their vicinity. (TV: Regeneration, Robot Gladiators, Hound of the Korven)
