The Hypnos-T Type was an experimental model of Tyrant seen at Sheena Island's "Tyrant Plant". The main variation between this Tyrant and other models was the inclusion in its genetic make-up of the Hypnos gene, a modified genetic strand that, when implanted into an organism, would kill the weaker cells through natural selection, leaving only the best to keep the organism ongoing and encouraging the reproduction of the better cells. A neurotransmitter known as "β Hetero Nonserotonin" was also necessary for its creation. Its name originates from the Greek word for sleep, "Υπνος".
In its original form, Hypnos-T Type resembled a genderless and hairless youth. Once awakened, it proceeded to kill the commander of the Sheena Island base, Vincent Goldman, while he was talking to detective Ark Thompson, before turning its attention to him. After a brief conflict in a small corridor, the creature was knocked unconscious.
Its only attack in this form was using its sharp clawed arm to stab its prey.
Unbeknownst to Ark, the creature was alive and continuing to mutate. These mutations granted it greater muscle mass, much larger claws on its left hand, an enlarged jaw, and sharp teeth.
In this state, the Tyrant could run at high speeds and viciously slash its opponents. It could also perform a downward strike. Its most dangerous attack was a powerful jumping strike performed at a distance. Lastly, it could strike with a swift lunging strike.
Nearly defeated in a second encounter with Ark on a Helipad, the creature began to mutate again.
The creature lost much of its intelligence in the process, suffering through a form of hypertonia, and losing its humanoid shape, becoming a bestial, primate-like, hunched monster. Because of the excessive muscle growth, the Tyrant was rendered vulnerable, with the heart becoming exposed as is common in its brethren. These new weaknesses didn't make it any less agile, however. It compensated for the exposed heart by shielding it with its claws.
Hypnos-T Type fought a long, grueling battle with Thompson, but in the end it was destroyed when it leapt upon Thompson's escape helicopter, at which point a sidewinder missile was launched into its abdomen. Seconds later, another missile was launched against it, detonating both and killing it once and for all.
One of its attacks lifted his opponents, impaling them in its claw and throwing them around as though they were a rag doll. His other attacks included a shoulder tackle (reminiscent of the ones performed by the T-103s encountered all over Sheena island), and a jump strike. It is also worth noting that despite two Sidewinders — which are significantly more powerful than any shoulder launched weapon — detonating on it is simultaneously it still made one last scream showing it's ferocity and resiliency.
