Tyrant-Armored Lethal Organic System

Tyrant-Armored Lethal Organic System, or T-A.L.O.S, is from the video game Resident Evil: The Umbrella Chronicles.

Creation
T-A.L.O.S. was originally an idea that was conceived by a team of North American researchers from the Umbrella corporation. They wanted to create the ultimate Bio Organic Weapon (B.O.W.) that would surpass every other model. The biggest objective was to maintain full control of the B.O.W. The researchers began the project in the Arklay mansion on the outskirts of Raccoon City.

In Europe, another team of Umbrella researchers collaborated on the project. They discovered that using an organic parasite was a possible method to control the B.O.W. However, the North American team discovered a better method of control: connecting microchips to the B.O.W.'s brain cells. The final decision was that microchips would used to control the B.O.W. through its brain cells. The chips would be maintained by the Red Queen super computer.

The North American researchers weren't fully satisfied with the current development. They wanted the new B.O.W. to have equivalent to military hardware. Normally, Tyrant models are strong enough to take on multiple army troops. However, they aren't able to battle large military vehicles. The team's solution was to arm the new B.O.W. with specialized firepower and enhanced armor.

After intensive research, production of the new B.O.W. was scheduled to began. It was named T-A.L.O.S. (short for Tyrant-Armored Lethal Organic System). Before production could begin, it was interrupted by an outbreak of the T-Virus. The outbreak was caused by James Marcus who was a former researcher of Umbrella. This event startled Oswell E. Spencer who was the founder and president of the Umbrella corporation. Afraid of what might happen at the Arklay mansion, Oswell ordered Sergei Vladimir to recover T-A.L.O.S. Sergei and his personal body guards went straight to the Arklay mansion. They managed to escape with the only prototype of T-A.L.O.S. At this point, T-A.L.O.S was safely back in Umbrella's hands.

Relocation
Following the outbreak in Raccoon City, the Umbrella corporation was forced to go underground. Most of its activities were shut down by the government. The T-A.L.O.S. prototype was moved to Umbrella's Russian branch which was the company's last stronghold. Under Sergei's guidance, T-A.L.O.S. was completed. The new weapon was tested against an attack helicopter, special forces, and two armored vehicles. The T-A.L.O.S. outperformed all of them. However, rumors of Umbrella's new bio-weapon began to spread

Deployment
On February 18, 2003, the Russian stronghold was attacked by S.T.A.R.S members Chris Redfield and Jill Valentine. After hearing about the rumors of T-A.L.O.S, they led a squad of troops. Jill and Chris managed to break into the stronghold but they encountered hordes of zombies. At the same time, they descend deeper into the stronghold. Soon, Chris and Jill enter a very large chamber. They are greeted by Sergei's voice over an speaker. After boasting about the potential of T-A.L.O.S, he activates it. Chris and Jill are forced to fight for themselves. T-A.L.O.S runs around the chamber while using a massive rocket launcher. Despite the heavy crossfire, Chris and Jill manage to defeat T-A.L.O.S. At first it falls to the floor. Seconds later, it mutates into a larger and powerful beast. After sticking to the ceiling, T-A.L.O.S uses its claws and tentacles to kill Chris and Jill. They find the monster's weakpoint on the back of its body and shoot it. After killing T-A.L.O.S, Chris and Jill leave the stronghold. Meanwhile, Albert Wesker personally confronts Sergei.

Structure
T-A.L.O.S. uses a Tyrant as a base, while adding remote computer control capabilities via a chip implanted in the brain. Its cardiovascular system is artificially improved, giving it mobility unthinkable in a natural organism. Its body is armoured in a special metallic alloy that not only helps it defend itself from missiles and other projectile fire, but also restrains runaway t-Virus mutation. It has also been equipped with a homing MRL weapon system to allow it to respond to distant targets. The T-A.L.O.S. can use its massive left arm to either sideswipe or crush opponents, and its rocket launcher has a rate of fire similar to a sub-machine gun. Although it is a humanoid B.O.W., it has enough armour and firepower to stand against a tank. After being defeated in this form, T-A.L.O.S. mutates; most of its armour and long-range weapons detach, its legs disappear, and it anchors itself to the overhanging Red Queen. This form begins to utilize more physical attacks, such as flinging pieces of the ceiling with robotic claws mounted on tentacles. Its arms have mutated into massive appendages ending with enormous claws, allowing T-A.L.O.S. to swipe at and crush its enemies.
