Bumblebee

ORIGINS:

When the Autobots and the Decepticons awoke on earth in 1984, Bumblebee was one of the first to explore this new planet. 

Eager to see the new lifeforms called humans, Bumblebee was unfortunately injured by a Decepticon and became stuck in car mode. He was found by a human called Buster Witwicky who took him back to his father's garage and repaired him. He was shocked to see the little car transform into a robot, but the two became good friends.

Bumblebee was targeted by the Decepticon leader Shockwave as the weakest of the Autobots. He was forced to take refuge in a old car lot and was stolen by two teenagers. He saved them from the Decepticons and was saved himself by other Autobots.

G.I. Joe mistook Bumblebee for a Decepticon and destroyed him, but with Ratchet's help he was able to reconstruct Bumblebee and renamed him Goldbug.

Goldbug's body was destroyed by the rapid anti-robot assault team, but his brain components were placed in a toy car.

His body was reconstructed by the Autobot headmasters resurrected Optimus (who had recently died).

Goldbug was deactivated by Starscream and then reactivated by Ratchet along with Jazz and Grimlock.

Bumblebee, Jazz, and Grimlock were transported to the center of Cybertron and found Primus, their god. Unicron began his decent to Cybertron, and Bumblebee, Jazz, and Grimlock went to the third moon of Cameron to search for the Creation Matrix, the only thing strong enough to stop Unicron. Thunderwing claimed the Matrix for his own, but Bumblebee, Jazz, and Grimlock were saved by the Autobots.

Sam enters the car and he's praying not to let Mikaela go home like that, and the car suddenly stars, with the radio now playing "Baby,come back". Sam then drives Mikaela home.
Later that night, Bumblebee goes to a secret meeting place to summon the Autobots. Sam follows him, but he gets arrested. In the morning Bumblebee returns, Sam takes his mother's bike and runs away with Bumblebee going after him. Sam meets up with Mikaela again saying her that his car is possessed and chasing him.

Sam escaped but Mikaela arrived. Sam warned her to run, but she didn't. Finally they both were saved by Bumblebee, who after a hot pursuit defeated Barricade. They learn that Bumblebee is an alien robot too. Mikaela and Sam were driving through a tunnel where Mikaela called Bumblebee a "piece crap Camaro". Bumblebee hearing this dropped them out from the car and took the form of a shinny 2009 Camaro. After they meet up with the Autobots,Bumblebee was captured and tortured by Sector 7 after he tried to save Sam and Mikaela from them for wrong accusations.
Taken to the Hoover Dam, the main base of the Sector 7, he learned that Megatron is kept there frozen. Bumblebee was set free by Sam who gained the trust of the others and went to Mission City to protect human life from the invasion. He was damaged badly during the fight. He survived and stayed with Sam Witwicky as his guardian.

TRANSFORMERS:REVENGE OF THE FALLEN(2009)

Bumblebee is living in Sam's garage and is called upon to help Sam deal with the appliance bots. Bumblebee destroys them all, but also does a lot of damage to the house and is upset as he knows he's in trouble. Bumblebee still can't speak well and uses the radio to talk. He's excited at first at the thought of going with Sam to college, but is upset when Sam tells him he can't go. Sam says goodbye and tells him to go back to the other Autobots which he does.

After the Allspark shard is stolen and the government wants to have the Autobots leave Earth, Bumblebee is dispatched by Optimus to get Sam for a meeting so Optimus can get Sam's help in dealing with the government. Bumblebee arrives at the party Sam's at and parks on the lawn, angering the frat boys and inadvertently saving Sam from Alice's advances, who happens to be a Decepticon Pretender. Sam tries to take off in Bumblebee (who his roommate Leo is impressed by), but Alice joins him and continues to hit on him. Bumblebee severely disapproves of her actions and plays dirty music and sprays coolant all over her, ultimately causing her to leave. Bumblebee takes Sam to Optimus where Sam refuses to help them anymore, wanting a normal life.

Later, when Sam, Mikaela and Leo are captured by a resurrected Megatron, Bumblebee and Optimus rescue them and Bumblebee takes Leo and Mikaela to safety while Optimus takes Sam. Bumblebee arrives just in time to save Sam from Megatron, but not before Optimus is killed. Bumblebee, Sam, Mikaela, Leo and the Twins Skids and Mudflap end up hiding in an abandoned prison while all of the rest of the Autobots return to an air force base and are taken captive by the government.

After seeing The Fallen's broadcast and learning that the government is after him, Sam falls into a depression and Bumblebee tries to snap his friend out of it and convince him not to turn himself in. With Mikaela's help he ultimately succeeds. When the group decides to go to Leo's rival RoboWarrior for help, Bumblebee acts as the group's mode of transport (and does so for the rest of the movie although Sam seems to drive most of the time). After uniting with RoboWarrior, who turns out to be their old "friend" Simmons, Bumblebee transports the group, now including Simmons, to the Smithsonian where the group revives Jetfire and recruits him to help. Jetfire transports them to Egypt via a space bridge and explains the history of The Fallen and the Dynasty of Primes, which is something that the Twins and Bumblebee are unaware of. The group leaves Jetfire behind and takes off to find the Matrix of Leadership to resurrect Optimus with.

The group spend the night at the Great Pyramids of Giza and the next morning head to Petra when Sam figures out where the Matrix is. After tracking down the right tomb and finding nothing, the Twins start to fight, and Bumblebee, annoyed, bangs their heads together and tosses them out of the tomb. The two's antics reveal Cybertronian glyphs and Bumblebee blast a hole in the wall into the room where the Matrix is held. He is as disappointed as everyone else when it crumbles to sand, but goes along with Sam's assertion that it will still work.

On the way, the group is attacked by Megatron and Starscream and Sam sends Bumblebee and the Twins to distract them. Leo and Simmons go with the Twins while Bumblebee goes by himself and Sam and Mikaela head out to reunite with the soldiers.

Bumblebee loses his pursuers and heads into town to find Sam's parents held hostage by Rampage and Sam in a tight spot. Sam is the only one who spots him and distracts Rampage and maneuvers him closer to Bumblebee who attacks. During the fight, Ravage attacks him too, but Bumblebee kills Ravage and then Rampage. Bumblebee reluctantly takes Sam's parents to safety on Sam's orders.

Later, Bumblebee returns during the battle with Sam's parents when Sam is killed and is visibly devastated by Sam's death. He is shocked but happy when Sam is resurrected by the Dynasty of Primes and witnesses Sam resurrecting Optimus with the Matrix which he earned. He witnesses The Fallen's return and Jetfire's sacrifice to help Optimus.
