Nexus
From Tardis Wiki, the free Doctor Who reference
Nexus was a being from an other dimension. It fed on large mollusc, and when it fell into the Doctor's dimension, it became confused and attacked Tokyo thinking it was food. Raine Creevey, Sergeant Pete Wilson and the Other Doctor went to investigate. The Other Doctor hypnotised it to jump into the sea and die. (AUDIO: UNIT: Dominion)
