"'KEEP DAWDLING ON AND ON YOUR CABLES WE'LL PISS!!'"Lrak is a member of the Adeptus Custodes. Like some other Custodes, he chooses to shed his armor, but is a different brand of crazy from the Fabulous Custodes.

TTS Canon
Lrak first appeared alongside the rest of the Custodes when they intervened to kick Fyodor Karamazov out of the Imperial Palace, but had no speaking parts. Lrak later joined Kitten and the rest of his forces for their mission to Mars, where Lrak made his deranged personality known with his crude outbursts.

Lrak threatened the Fabricator-General of Mars with pissing on his cables if he did not give up the location of the Proteus Protocol.
