Fight or Flee is a good episode. It starts with Cyclonus and Scourge chasing the Aerialbot Skydive through space, which ends up being a trap. The two Decepticons fly through a warphole where the end up injured on the planet Paradron, a planet which according to Cyclonus, looks like Cybertron during the fabled "Golden Age." The two wind up assaulting the pacifist Autobot Paradronians, and take over the planet with the help of Galvatron and the other Decepticons. This leads Sandstorm to take off and seek help from the Autobots on Cybertron.
The two factions as usual go to war, which leads in Magnus needing to detonate the planet's energon core to stop the Decepticons from getting more powerful and destroying the universe. Sandstorm and his friends go on to join the Autobots on Cybertron, and Sandstorm teaches his people that it's alright to fight for what you believe in.
All in all, aside from the cliched Autobot Vs Decepticon battle theme, it's a good episode, which shows what happened to some of the other races of Transformers who left during the great wars on Cybertron. Sandstorm is a good character, and has more testicular fortitude than his people, and takes up arms and fights when he was to. Sandstorm only speaks in this episode, and in Starscream's Ghost, but he's still an awesome character.
