Transformers 3

Here's what I can make of it:
- The Autobots and Decepticons are still at it (surprise surprise).
- Optimus and Sam consult an Astrophysicist about ANOTHER unknown shard of the all spark.
- Using the Hardon Collider, they can extract energon from it, infinite source.
- Optimus believes one of his ships 'the ark' could accomplish the same thing.
- Deceptions find out about all this, make plans to destroy source of energon.
- Sam plans to marry Mikaela etc etc.
- Decepticons plan out their moves while sam and bumblebee move the spark to the ark.
- BUMBLEBEE TALKS!!!
- Sam and Mikaela drive to the ark that lands in france (ya, rly)
- They all go into space on the ark, while the autobots begin extracting energon.
- Sam almost proposes but then BLAST! a Decepticon ship attacks the ark.
- Decepticon ship teathers to ark, optimus fires teh lazers, weapons reach critical mass
- critical mass + all spark = flash and both ships disappear
- reappear and blast tears through decepticon ship, both ships fall towards earth
- autobots eject reactor core to save humans (?!?)
- ark and decepticon ship crash, starscream kills megatron
- they have GONE BACK IN TIME!! to 1982.
- Starscream steals nuclear weapons off a F-15 fighter plane and heads off
- at the ark, sam and mikalea try to get the autobots online
- military gathers around ejected reactor while starscream attacks hoover dam
- starscream finds the all spark cube and takes off
- starscream is about to kill past megatron (frozen) but collapsing dam forces him to leave.
- sam finds optimus' reset button, all autobots are fine, astrophysicist is pwned.
- past megatron is fine, he takes off.
- the autobots figure out they went back in time, all spark is intact
- Leo actually says 'Hold on Doc Brown that only works in Star Trek' and my soul died a little.
- starscream hides the all spark and takes off
- autobots chose time appropriate disguises (make a trailer disappearing off optimus reference that was sort of funny...)
- silverbolt goes to disable sun harvester, sam and bumblebee to hoover dam
- megatron is attacked by tanks, but becomes one and destoys all, finds decepticon signal.
- sam arrives at hoover dam, sees its destroyed and informs optimus
- sam meets man, dr davidson, with non time period device, leaves anyway
- starscream returns to ship, finds past megatron there, and they begin to plan again.
- clothing montage with sam and mikaela, punks attack them and bumblebee intervenes.
- sam and mikaela break into dr davidsons house
- silverbolt disables sun harvester, gets power matrix and returns to ark.
- humans examine reactor they found in desert to no avail, sending a signal to autobots.
- decepticons also pick up signal from reactor and head off
- turns out dr davidson is actually sams grandfather, herbert witwicky, sam explains all
- megatron has all forces in place and is ready to strike
- herb leads sam to the attached airplane hangar (wtf) and his secret underground base.
- herb explains about mystic space metal that connected his dad , who found megatron, to the all spark and made him knowledgeable.
- only two symbols that could be translated from mystical space metal is 'vector sigma', and it is the key to the heart of cybertron, and could lead to the all spark.
- decepticons begin to attack base to retrieve reactor, they secure the base.
- sam takes the key to cybertron and leaves while megatron is held up at area 51.
- they return the key to optimus, who plans the attack on area 51 to reclaim the reactor.
- only the decepticons ship is travel worthy, so the autobots use the matrix to repair it.
- optimus + others arrive at area 51, unopposed.
- optimus scouts ahead and is then ambushed, and battle commences!
- battle shifts back and forth til soundwave is killed
- sam finds all spark reactor while the autobots gain the upperhand
- remaining decepticons combine into one big one BRUTICUS MAXIMUS!
- air raid and fireflight intercepts starscream attempting to escape and subdue him
- to combat BRUTICUS MAXIMUS, the 5 aerialbots combine into SUPERION!
- the combined force of remaining autobots and SUPERION destroys BRUTICUS MAXIMUS!
- optimus stops megatron and subdues him
- sam free captured humans and explains all
- the autobots fly in the decepticon ship and pile everyone on, megaton and starscream are sent to the bridge.
- they connect the ship to the key to give a reading of where the all spark is.
- they connect the reactor to the decepticon ship, and the ship takes off into orbit
- turns out starscream put the all spark on mars and they head off
- just as they are almost there, and megatron and starscream are arguing, starscream presses a button that sets off the nuclear bombs he left on mars and destroys the all spark.
with it destroyed, as in the original timeline, and they return to their original time. BUT..
Now hopefully I'll get this right:
The all spark WASNT destroyed, mars became a new cybertron and the autobots colonised it. Soon though, the decepticons attacked and claimed new cybertron while the remaining autobots fled to earth. in the past, optimus and most of the autobots have been killed defending the autobot city on earth with ultra magnus, but now they are here, traveled forward in time and, arg, I DONT KNOW OK!! They have the key to cybertron and they are going to mars. THERE! THE END!!
