The Kronosaurus is a marine reptile that served as the main antagonist in The Trench. There were at least three kronosauruses that lived in the Mariana Trench, where they had evolved to hunt in packs and develop gills.
History[]
They were first met by Proteus when he explored the Mariana Trench. The Kronosaurs later devoured the bodies of Sergei and Captain Hoppe and also tore up the Epimethius when Terry boarded. A kronosaur that entered the benth's research station tried to devour Benedict Singer, but was killed along with Benedict when the walls of the room they were in were destroyed.
The second Kronosaur was killed because the pressure in the environment he was in changed and caused his head to explode, while the third and last Kronosaur was killed by Angel. Kronosaurus was listed in MEG: Hell's Aquarium as one of the prehistoric marine reptiles that Dubai Aquarium David wants.
