Monitor

“	Monitor: Insentient autochton of the planet Aster Colora. It has the appearance of a Terran monitor lizard, but is a kilometre long and weighs an estimated 4.5 million tonnes. It is a silicon-based lifeform with an alien physiognomy.	„
—Gridlinked, Chapter 11

Monitor is controlled by Dragon and is presumably destroyed when Dragon appears to obliterate itself with a contra-terrene explosion.
