Nessie is a species of Mosasaur that survived in Loch Ness and only surfaces every 20 years to mate. Unlike most of the creatures in the series, Nessie is not a mutation. Nessie and her species lived in peace until her baby was kidnapped by a scientist. H.E.A.T was visiting Scotland, and investigate. Zilla appeared and the two battled. It wasn't until later that Zilla discovered Nessie was only attacking in order to find and save her baby. Zilla then would team up with Nessie and help her rescue her infant. To date, Nessie is one of the only friendly monsters, other than Zilla, to be encountered by HEAT.
Trivia
- The Nessie creatures are likely to be a reference to the Toho kaiju Manda, as the two have long, serpentine bodies and have aquatic habits.
