Loky is a beast associated with the Sants neighbourhood, representing a chimera, a winged mythological creature with the head of a lion, body of a goat and tail of a snake. It has a structure on wheels that is pushed along about by members of the Colla de diables Guspires de Sants and that allows one of these accompanying devils to climb on top. When it is dark outside, both its lion's and snake's eyes light up, a feature that adds to its aggressive appearance.

The idea to build this monster came from the colla, who wanted a  fiery beast to liven up the pyrotechnic displays alongside the devils. The artist Dolors Sans, from Vilafranca del Penedès, was commissioned to design it and in 2013 Loky, the only chimera among Barcelona's festive imagery, was born.

Loky was presented in Sants in June 2013, at a ceremony in which two other Dolors Sans figures, Sírius the Cat from Poble-Sec and Nébula from Trinitat Vella, also took part. He has been taking part in the Guspires de Sants gatherings and pyrotechnic shows ever since, in the neighbourhood and elsewhere, accompanied everywhere by devils and kettle-drummers of all ages.
