The Transformers' arrival on Earth in the 1984 cartoon is one of the franchise's best-known scenes. It explains why alien robots disguise themselves as our cars.
Escape from Cybertron
The Autobots, led by Optimus, leave Cybertron aboard the Ark to search for new energy sources. The Decepticons pursue and board the ship. During the fight the Ark loses control and crashes into prehistoric Earth.
Millions of years of sleep
Every Transformer on board is knocked offline by the impact. The ship lies inside a volcano for millions of years until an eruption in 1984 activates the onboard computer, Teletraan-1. It revives the warriors and gives them new forms based on the Earth machines it 'sees': cars, trucks, jets.
Why it matters
This story set the franchise's core formula: an alien war carried into our everyday life. Robots hide among cars, humans become their allies and Earth becomes a new battlefield. Later films and series changed the details, but the idea stayed.
