RED ALERT 2: Yuri's Revenge: Enemy Unknown

Triffidia

No one really knows where the Triffidia stem from. Is it an alien lifeform? Is it a terrestrial genetic experiment gone wrong? The only thing we can say for sure is that it is a threat to all life on Earth. The Triffidia has both plant and animal characteristics and clearly possesses intelligence. Unlike most life forms, it seems to propagate by cultivating a single organism which the offspring both maintain and are maintained by. Only when a new 'parent' entity is required does one of the offspring begin to develop. A parent entity can develop at an alarming rate, expanding through miles of terrain in mere days, crushing entire cities as it grows.
Brain
This is the sensory core of the Triffidia entity. It is responsible for the growth of all new organ structures. Without the Brain, the rest of the plant will soon die.
Root Node
After the Brain, Root Nodes are the most vital part of the Triffidia. Roots connect the various organ structures together as well as absorbing additional minerals directly from the earth. Root Nodes can latch on to buildings, entangling them and allowing the Triffidia to absorb their resources.
Vein Hole
The Vein Hole is a complex system of roots that can metabolize inorganic matter. Vein Holes spawn Visceroids that can harvest minerals and return them to the hole for absorbtion. Further Visceroids are created here for other purposes (see the Visceroid entry below). Any unit under Triffidia control can be destroyed at a Vein Hole, to be broken down into raw materials.
Chlomatospore
This is the main organ responsible for creating Visceroids, the only unattached unit that the Triffidia commands. Whilst new Visceroids seem to take a long time to grow, every Chlomatospore will produce a Visceroid simultaneously. Before a Chlomatospore can create Visceroids, a Vein Hole must be present to provide sufficient biomatter. Whilst every Chlomatospore will produce a Visceroid simultaneously, only one Vein Hole will do the same and is usually the Vein Hole closest to the Brain.
Entangling Roots
Entangling Roots lie hidden in the ground, preying on soldiers and tanks alike. When an enemy moves close the roots shoot up out of the ground and entangle them, preventing them from moving and slowly crushing them. If the roots are destroyed quickly enough the entangled unit can be freed.
Lightning Flower
The Lightning Flower has at its heart an organic-based cold fusion power source that can produce enough energy to hurl lightning bolts at the Triffidia's enemies. Neighboring Lightning Flowers can support each other by feeding energy from one flower to another.
Lysosome
The Lysosome is an organic explosive. The Triffidia responds to infantry and vehicles much like an infection. If a significant threat is perceived then these hidden Lysosomes will explode causing destruction to both the aggressors and the Triffidia itself.
Evolutionary Metamorphosis Accelerator
•Once t his organ has been developed, the parent entity's growth rate doubles.
•EMAs grow tissue more efficiently, requiring less biomatter to create new organ structures.
•The EMA can rapidly grow a skin of chitinous armour around several objects in the local terrain. This has the effect of making Triffidia organ structures invulnerable for a short period of time or destroying infantry and vehicles.
•If given enough additional biomatter, the EMA can extend a strong system of pulsating roots deep underground, allowing the Triffidia to effect earthquakes where a threat is perceived.
•Finally, the Accelerator can forcibly develop a Visceroid into a parent entity by increasing its growth rate by a factor of thousands, allowing a new parent entity to be created in a matter of minutes. However, this happens infrequently as the biomatter requirement is extreme.
Visceroid
Visceroids could be compared to blood cells but in truth they defy definition. Visceroids are the Triffidia offspring and have multiple functions within the parent entity. Some are used to harvest minerals, others are responsible for healing damaged tissue and some will actively defend the organism by attacking its enemies. A Visceroid can develop into a new parent entity but this process takes several weeks.
