Dalek X

Dalek X is one of the most sacred and fearful dalek before the Time War. His name was told across the universe and it was every bounty hunters fear to encounter him, yet every bounty hunters dream to defeat him. He lasted until just before the Time War when it met the Doctor. After enslaving the Doctor and bounty hunters team, he thought himself victorious over a Time Lord. Allowing the Doctor to take him back to the planet he found them for the TARDIS the doctor tricked them. Leading Dalek X into a room about to explode the Doctor escaped in his TARDIS, taking the surviving bounty hunters with him. Dalek X was thought to die in that room although hours or even days later the Doctor recognized his radio waves broadcasting across the universe for help and so homed in on him. The Doctor finished what he had started, leaving Dalek X to suffer forever in the darkness, living off of life support systems, never being able to find help as the planets systems stopped fellow Daleks from receiving the beacon.
