Kloak, known as Yamimaru in the Japanese version, is a character appearing in Taylor Gorrell's Yu-Gi-Oh! GX Alternate Season 4. A new member of the Light Brigade, he is the holder of "Caius the Shadow Monarch".


Kloak is a pale-skinned young man pitch-black hair and navy blue eyes. He typically wears a dark purple cowl, complete with long sleeves, which covers the rest of his outfit. Underneath the cowl is a purple shirt, black sweatpants, and black shoes.


Kloak is a reserved character with a tendency to speak in poetic dialogue. While he appears distant, he's actually quite friendly and able to make small talk.



Through Caius's power, Kloak can vanish instantly by turning into a shadow through his cowl.


Fitting his name and position in the Light Brigade, Kloak plays a Shadow Deck, which has a largely evasive strategy. His primary card is "Caius the Shadow Monarch", which he can eventually upgrade into "Caius the Mega Monarch".
