Dr. Octopoid, Occult Detective From Beyond Space and Time!

Courtesy of Flames Rising's Horror Plot Generator:

A gigantic octopus with psychometry, whose home base is in a Victorian funeral home, wants to bring the Earth closer to the sun. Supported by falcons, the gigantic octopus appears to have one weakness - bat tongues. Interestingly enough, the gigantic octopus is from the not-too-distant future.

Sounds silly at first, but consider this rewrite: in the last years of the twenty-first century, as civilization collapses due to an apocalyptic Ice Age, a small band of scientists use time-travel technology to send the consciousness of one of their own back in time to prevent this coming catastrophe. Now trapped in the body of a giant octopus, the futuristic Doctor, armed with hi-tech psychic powers that allow him read the sensations of memory by touch and control the minds of lower life-forms (like his flying army of falcons), plots from his tank in the basement of a Victorian funeral home, where he builds, with a workforce of cadaverous conscripts, giant rockets underneath London that will push the Earth further towards the Sun and save mankind from an icy demise two hundreds IN THE FUTURE!

And he also solves crimes and shit with the help of his plucky monkey assistant and a hot corset-wearing suffragette.

And he's allergic to bat tongues.
