Time Bomb (comic story)

Summary
The Sixth Doctor and Frobisher are traveling in the TARDIS on their way to meet Peri for a baseball game on Earth when the TARDIS is hit by a time cannon -- a technology which only Gallifrey is supposed to possess. Intent on finding the cannon and destroying it, The Doctor materializes the TARDIS at the cannon's origin point on the planet Hedron. The Hedrons had used the cannon to destroy all traces of genetic imperfection in their species.

As The Doctor and Frobisher exit the TARDIS they are captured by a robot and placed with the other genetic imperfection and hit with the time cannon which sends them back to prehistoric Earth. Luckily, the TARDIS is also hit by the canon and travels with them. The Doctor locates the cube of genetic imperfections and takes it with him in order to prevent it from contaminating life on Earth. But before he and Frobisher can reenter the TARDIS, bodies of dead Hedrons begin to appear. It seams as if the Hedrons are continuing to use their cannon.

Although he is desperate to prevent the Hedrons from contaminating earth any further, he decides that he should pick up Peri in case she could help talk to the Hedrons. Materializing in New York City in the year 1980, The Doctor and Frobisher find Earth controlled by sentient reptiles. Apparently the Hedrons' genetic material has altered the course of life on Earth so that humans never evolved.

The Doctor and Frobisher bid a hasty retreat and return to prehistoric Earth in order to attempt to reverse the damage done by the Hedrons. While The Doctor mulls over the situation, Frobisher decides to grab a bite to eat but before long a large aquatic dinosaur decides to try to eat him. In an attempt to rescue Frobisher, The Doctor grabs the nearest object and hurls it at the dinosaur. Unfortunately, the nearest object was a sphere containing Hedron genetic material which smashes open causing the dinosaur to flee but also irreversibly contaminating prehistoric Earth.

Angry that Frobisher has caused him to further contaminate life on Earth The Doctor and Frobisher return to Hedron so that they can at least destroy the time cannon and prevent it from doing any further damage to the universe. When they arrive on Hedron, however, they find that everyone has died through some terrible cataclysm. Finding a recording from one of the last Hedrons they learn that the cause of the destruction was a space ship that had crashed on the planet, releasing microbes and poisons which the Hedrons had eliminated and to which their immune systems had no defense. As it turns out the origin of the deadly space ship was none other than the planet Earth. Thus, time had healed its own wounds and the genetic material that the Hedrons had banished from their planet had come back to them with deadly results.

The Doctor destroys the time cannon and he and Frobisher take the TARDIS back meat Peri in New York City in 1980 for a baseball game. As The Doctor exits the TARDIS he ponders if they will be able to sneak into the game without paying. This seems unlikely, however, as the final panel reveals that The TARDIS has materialized in the middle of the baseball field.
