Transformers Generation 1 was a very good series.

Here is the order of the seasons as shown in the video: 1,2,5,3,4. The movie take place between seasons 2 and 3. The first 2 are set in the 80s (when it was made) the movie skips ahead to the future.(the 2000s Ha! X) Lol!)

Here are the two different leaders of the Autobots: Rodimus Prime (future 2006!) Optimus Prime (present 80s!)

I actually didn't make this video!

This is the theme from that cartoon Transformers movie.

Something evil's watching over you
   Comin' from the sky above
   And there's nothing you can do

   Prepare to strike
   There'll be no place to run
   When your caught within the grip
   Of the evil Unicron

   Transformers
   More than meets the eye
   Transformers
   Robots in Disguise

   Strong enough to break the bravest heart
   So we have to pull together
   We can't stay worlds apart

   To stand divided we will surely fall
   Until our darkest hour
   When the light will save us all

   Transformers
   More than meets the eye

   Autobots wage their Battle
   To destroy the evil forces
   Of the Decepticons

   It's judgment day and now we've made our stand
   And now the powers of darkness
   Have been driven from our land

   The Battle's over but the war has just begun
   And this way it will remain til the day when all are one
