An extragalactic parasitic species that intends to assimilate all of existence into its hive mind. Controlled by a single 'Gravemind'. Primary Antagonist of Halo Series. Halo Array created to subdue the Flood by starving them to death.
Cycloptic, plant-like creatures from planet Flors Verdance who can control plants. They can generate seed bombs that unleash knockout gas or vines to trap enemies, stretch their arms far distances, generate thorns on their bodies, and merge with plant life.
A race of energy beings hailing from planet Fulmas, these warlike aliens are very dangerous. Resembling stone-armored beings made of blue electricity, they are masters of controlling electricity, and are able to absorb energy as well. Their MO is to create a wormhole to a new planet and suck it dry of energy, as they need the energy to keep Fulmas from falling apart.
