Trivia

 * Gigalith was first seen along with Reuniclus and Gothitelle on Oha Suta on June 28, 2010. Later it was seen in battle against Blitzle, Darmanitan and Drilbur.

It was also appeared on the September issue of Coro Coro on August 9, 2010. The Romanization of the name Gigaiasu was later revealed to be Gigalith
 * Gigalith's name may have been derived from ギガス Gigas, a term used to describe a race of chthonic (Earth-associated) giants, and the word "monolith", a large single upright block of stone.
