The Mega Trogg was an extradimensional behemoth that served as the main antagonist in the film, Gnome Alone.

Biology
The Mega Trogg was described as a gigantic purple monstrosity with glowing eyes with a rather blob-like appearance. It had been merged from all of the other Troggs as they morphed together into this massive creature. The Mega Trogg appeared during the final battle shortly after when both Chloe and Liam along with the gnomes had destroyed the Trogg Dimension.
