Riksis

Riksis was a Fallen Archon. The Guardian faced him during the story mission Restoration.

History
Riksis was once an Archon of the House of Devils. He would collect the skulls of dead Guardians and likely serve them to his Prime as offerings. However, after a powerful Guardian and their Ghost returned to collect a Warp Drive they had left behind their newfound jumpship, it was revealed the Drive they were searching for was already in Fallen - and most importantly, Riksis' - hands.

Riksis, along with the rest of the Fallen in Dock 13, was destroyed; it is said that Riksis' death resulted in great joy in The City at the time where it needed hope the most.

Physical Description
Riksis was much larger than his Fallen brethren, due to his rank as a high Archon Priest. He looked similar to that of most Captains, but lacked a shield, something all Captains share.

Riksis wielded a powerful Shrapnel Launcher that was capable of downing Guardians in seconds, as well as a melee attack he would use only if foes got close.

Trivia

 * Prior to Destiny's release, Riksis' name and title was "Rixis, Archon Slayer."
