Also known as species 64, Trapanahena Oelis or T Oelis is likely the most dangerous alien brought to Earth via the Majinino. While similar in shape and size to an octopus, the T Oelis' tentacles are much stronger, more agile, and more capable.
However, while the Teioelis is strong enough to wrestle an adult xenomorph, its real danger comes from its eye, the source of its nickname. The actual body of the Teioelis sits atop its tentacles, resembling a round eyeball surrounded by several independent optic irises. These irises can also combine and transform to mimic any optic configuration.
The Teioelis uses various animals, such as cats and sheep, as its hosts. Although it's unconfirmed whether the eye aimed to save the ship in past instances, it seemed confident it could take over a xenomorph. This means it may potentially use any larger creature as its host, even those evolving from other aliens if they have an eye socket.
Nicknamed 'the eye' because it replaces its host's left eye, the Teioelis utilizes the host's eye socket, which is not just a direct low latency line to the brain but also a center controlling facial sensations and movements. Once attached, it takes less than a minute for its tentacles to commandeer major motor functions. Disturbingly, the eye can align its irises to match the host's pupils, practicing this mimicry before making a lethal move.
Teioelis escaped captivity and communicated with captors, suggesting intelligence surpassing human levels. Its survival skills and interaction capabilities suggest it evolved for social engagement. A significant concern remains its untested biological adaptability — could the eye speak using a human host? The Teioelis may indeed behave indistinguishably from humans given enough time.
In the future, it might even access its host’s memories and skills fully, posing as a human, potentially covertly as dangerous as taking over a xenomorph. Notably, the first human involved with Teioelis, Boy Cavalere, is rendered vulnerable due to his left eye socket, prompting questions about whether this is by design. Why the left eye and not the right? Share your theories.
