- Motto: "The only good is knowledge, and the only evil is ignorance."
To my knowledge, no Decepticon Leaders has outright joined the Autobot, but temporary alliances have been made to deal with a greater threat, mostly done by G1 Megatron:
- in Countdown to Extinction, Optimus Prime used Megatron in gun mode to shoot the Exponential Generator into space.
- in The Revenge of Bruticus, Megatron and optimus Prime once again joined forces to deal with the Combaticons' plot to guide the Earth into the sun.
- in The Core, Megatron joined with the Autobots again when a plan involving the Earth's Core went awry.
- another teamup happened at the end of the Marvel G2 comics, in which Megatron famously stated his foolishness with his infatuation with Starscream
- In the Japanese G2, Optimus Prime and Megatron from the Cybertron Alliance, which quickly disolved when one of Megatron's friends was killed by humans on accident.
- In a bit of a cheat, in Robot Masters Megatron used the guise of Reverse Convoy to infiltrate Autobot ranks.
- In the Stargate Battles, Optimus and Megatron again joined forces, to stop Starscream.
