Zypedrian

Zypedrians are a race of beings that were seen in Terror of the Zypedrians. They attacked Earth in 2024 and, after being defeated by the Human-Venusian Alliance, began conditioning subsequent generations to vehemently hate the one who not only established contact with Venus but led the attack that forced the first brainwashers back to Zypedria – Christopher Davola.

In 4246, a stray Time War refugee allowed the Zypedrians, using his knowledge and derelict TARDIS, to create a single machine not unlike a Vortex Manipulator. They used this to send their greatest soldier to 1990, after which it killed Mr. Davola and took his place, revealing itself shortly after Mrs. Davola gave birth.

The beast was stopped by Daniel and Hannah Benfield by way of their Sonic Screwdrivers, being present after Daniel received information from the White Guardian.

Appearance
Zypedrians are "nightmarish" flying creatures with 70 massive teeth and a long nose-looking snout. They have a long reach, and although their intelligence tends to fade in and out (on top of being "not exactly bright"), their speech appears to slur. They are weak to sonic energy, which burn them to ashes.
