The Ron Friedman script
Some fans managed to get this one in 2010. The script is dated the 27th of April, 1985. This script would be heavily rewritten by other writers (most notably Buzz Dixon) as to make it more coherent and change many aspects that Ron had in mind. Some of the differences in this script include:
-It is only set 5 years after the first episode "More than Meets the Eye, Part 1", meaning the film would take place in the 1980s.
-Spike is not present, although Daniel is.
-The concept of "life sparks". In this script, the battered Megatron managed to get back to Cybertron with the other Decepticons, who start to fight over who will be the next leader. Megatron pleads for them to place his life spark into an urn, but nobody helps as they are all too busy fighting. A statue of a previous Decepticon leader falls over and crushes Megatron, shattering him. His life spark then leaves his body, and is found by Unicron. Unicron places Megatron's life spark into a new body, creating Galvatron. This entire life spark concept was dropped from the final film, although there is a small nod to it
in Starscream's coronation scene -there are several statues around the place, each one having an urn with a flame in it, which is what this script mentions.
-There are a few different takes on the shuttle attack scene, all of which feature the same Autobots getting killed (Ironhide, Prowl, Ratchet and Brawn). Most of the deaths are far more violent than in the final film, such as Brawn being blasted in half, whilst Ironhide and Ratchet get fused together and then blown apart.
-This script has characters who do not appear in the final film (such as Warpath and Powerglide) or larger roles for ones who only cameo (such as Sunstreaker, Bluestreak and Wheeljack).
-A scene with the "Roboto-zoo lab", which is part of Autobot City, and contains the "Ani-bots" -a team consisting of Pardo (leapord), Shriek (eagle), Thump (buffalo) and Clump (rhino). These Ani-bots get into a fight with the Constructicons. Later on, when the Constructicons unite into Devastator, Wheeljack gets the Ani-bots to unite into "Dragon Beast"! The two super robots start fighting, and Dragon Beast eventually wins thanks to help from the arriving Dinobots. Dragon Beast then starts smashing down some Decepticons jets. The Ani-bots are never seen in the final film, but it is possible that they eventually became the Predacons, a Decepticon team introduced in the third season of the cartoon.
-Blaster has different cassettes in this script. He has Cubbie (lion), Stripes (tiger), Stinger (scorpion) and Bolts (robot).
-There are even more deaths in this script, such as Gears been blown to pieces and Windcharger being ripped apart.
-Even the Autobots are violent in this script -there is a scene where Bluestreak uses a "laser saber" to cut Thundercracker in half! In this same scene Hound fires his weapon to blow off the legs of a few Decepticons.
-There is a scene where Optimus Prime's shuttle, which is heading to Autobot City, is attacked by Astrotrain.
-Unicron is handled differently in this script, as his planet mode is referred to as "Planet Unicron" whilst his robot mode is called "Ingestor".
These are just a few of the differences -I'd recommend any fan reading the entire script to see everything else which is different.
Whilst this script was heavily rewritten, Ron Friedman still gets the sole writer's credit in the final film due to a deal he made.
