Fans anticipating the arrival of Spock in the second season of Star Trek: Discovery will have even more to be excited about.

The CBS All Access series will bring back the very first alien species encountered on the original series of Star Trek, the Talosians.

A new teaser highlights the events happening in the eighth episode of the second season entitled, "If Memory Serves." The Talosians appear thirteen seconds into the clip but have more of an updated look from when they first appeared in "The Cage," the original pilot for Star Trek that was produced in 1965. Instead of the prominent blood flow seen in the prosthetic heads of the Talosians, computerized effects show pulses of energy rippling through their large craniums.

Spock (Ethan Peck) provides a voiceover to the montage of clips that begins with Spock's foster sister, Michael Burnam (Sonequa Martin-Green), leaving a shuttle and exploring what could be the surface of Talos IV. Burnam asks the Talosians to reveal her brother's mind and it's unclear if the images that follow are past memories or future images Spock believes will happen.

Besides seeing the Red Angel, the ominous figure that has been making numerous appearances throughout the second season, ships are shown firing torpedoes past a moon and striking a target that looks remarkably like Earth. A woman, possibly a younger version of Michael Burnam, is seen running away from structures rocketing out of the ground. Other images show a planet blowing up, Spock shedding a tear and the young woman from before being pulled out of frame, followed by Burnam waking up. Once she's awake, Spock asks her, "Now do you see?"

Talosians had amazing mental abilities and could also create illusions so real they were almost indistinguishable from reality. In 2254, the Talosians kidnapped the Captain of the USS Enterprise, which at that time was Christopher Pike. Pike would later be brought to Talos IV by Spock in "The Menagerie," a two-part Star Trek: Original Series episode. At that time, it was illegal to venture to Talos IV and doing so violated General Order 7, which stated, "No vessel under any condition, emergency or otherwise, is to visit Talos IV."

In Starfleet, breaking General Order 7 was the only crime that resulted in capital punishment. Star Trek: Discovery might shed some light as to not only why Starfleet doesn't want anyone to go to the planet, but also why they're willing to use deadly force to enforce it.
