Sekor Dom Sloathe
From Tardis Wiki, the free Doctor Who reference
Sekor Dom Sloathe was a Sloathe. It looked like a giant decomposing human brain.
It acquired one of the Eyes of the Schirron. It was believed that possession of all the Eyes would control the System. When it and Solan brought the Eyes they had to the Charon, it killed them since they were no longer useful, stopping Solan's heart and dropping a 10 ton weight to crush Sekor Dom Sloathe.
