Lumigeks are large, Phazon-charged reptiles found in the Impact Crater of Tallon IV. Lumigeks travel in swarms for a higher chance of survival, a trait shared by other creatures such as Ing Larvae. Though not aggressive, anything in the path of a swarm can be harmed by the Phazon energy Lumigeks emit.
