The Parasite Snake is an enemy that appears in Sonic Boom: Rise of Lyric. They are a model of Destruction Troops created by Lyric the Last Ancient with the dangerous ability to reanimate Commando Husks.
Described as worm-like in design, the Parasite Snakes have limbless strings for bodies, composed of grey threats held together by brown metal binds. They have a yellow eye with a slit-like pupil for a head, four collapsible lids for eyelids, and an appendage on the tip of their tail resembling a rattlesnake's.
Over a thousand years ago, the Parasite Snakes were created by Lyric the Last Ancient to aid him in his schemes to destroy the earth. When Lyric was imprisoned before he could carry out his plans, the Parasite Snakes were abandoned, though Lyric left some behind to be found so the finders could set him free to learn the Parasite Snakes' secrets. Dr. Eggman eventually found the Parasite Snakes and made them a part of his army, but after Lyric was freed, he soon reactivated/or and reclaimed all his Parasite Snakes.
The Parasite Snakes are not as common as the Swordsman Troopers, but still one of the more frequently met enemies in Sonic Boom: Rise of Lyric. They are first encountered in Lyric's Tomb. In gameplay, the Parasite Snakes always appear in groups and can be found emerging from small holes in the walls or on the ground.
In battle, Parasite Snakes attack by jabbing their target with their head. However, they are easily one of the weakest enemies in the game and can be defeated with one attack. What makes them dangerous is that they can reanimate Commando Husks by inhabiting them, thereby creating stronger and tougher enemies. Once they spot a Commando Husk, the Parasite Snakes will head towards it. Once they jump into it, it will only be a second before the Commando Husk comes online. To prevent this, the player can either destroy the Commando Husks or the Parasite Snakes before they reach it. When a Parasite Snake is defeated, it releases a single Ring.
After Team Sonic defeated Lyric, all the Parasite Snakes were subsequently scrapped.
- The Parasite Snakes' name were not revealed in the final version of Sonic Boom: Rise of Lyric. However, their name is listed in an unused biography for the game.
