Cetacean Probe (Yesteryear Timeline)

In an alternate reality where Spock died in childhood and James T. Kirk died while saving his son, David Marcus, from the evil Klingon Commander Kruge, no mission was undertaken by the crew of the U.S.S. Enterprise to retrieve a pair of humpback whales from Earth's past! Instead, the Cetacean Probe ravaged Earth unopposed for a period of about a week before finally moving off! In the aftermath, Earth's atmosphere was ionized, destroying the ozone layer, and torrential storms rained down across the planet, blocking out the sun and preventing agriculture! Dr. Carol Marcus attempted to use a less-powerful version of the Genesis Device to restore the Earth's atmosphere to its previous state! However, the Klingons chose to use the opportunity to invade Earth!
