The Tinghus

The Tinghus was a Tingha that, posing as the teddy bear Mr. Cuddles, took control of Ronald Turvey. A telepathic alien, the Tinghus planned to convert everyone on Earth into Tingha-Humans.

The Tinghus and Turvey were linked so that one needed the other to survive. Turvey turned on the Tinghus in anger at him having manipulated him. They both died as a result of their connection. (BFA: Cuddlesome)
