I've got a question... If the Decepticons were created as war machines, whos only purpose in life is for killing, what were they made to combat?

1. Any verse.

With the Transformes race in decline, the Autobots consult the Matrix on how to repoplulate their race. The Matrix reminds them of a long forgotten fact: All those with blue eye's are male and all those with red eyes are female.

Till all are one.

2. G1/bay

Decepticon Reinforcments arrive from Cybertron, one of which is Barricade. Noticing how similar Barricade is to the Autobot second in command, Prowl, Megatron orders a covert operation. Abducting Prowl midbattle, Barricade goes back to the ARC in his place. the Autobots don't suspect a thing.

Can he survive prank pulling Twins, a wrench throwing Ratchet and mounds of paper work long enough to gain any usefull intel?

3. G1

After the events of "B.O.T." Swindle pays for the grave mistake of selling his brothers for scrap metal. Playing a demented game of hide and go seek aboard the Nemisis, Swindle slips out of the base undetected. Thinking he's in the clear, he doesn't notice the autobots.

4. any verse

Soundwave knew this day would come. His sparklings couldn't stay young forever. That didn't make things better, though. It was the day... Rumble and Frenzy were to big to fit into his compartment. Heaven help the Decepticons.

5. G1 or Bay

Optimus remembered it vividly, it was an impossible day to forget. That day, long ago when the war had just started and he found Ironhide after a horrible battle.

Searching the wreckage for hostages and anything salvagable, he heard a shrill cry. Following it, he found a little child had been stashed beneath a hastily crafted shelter, made of a small sheet of steel and an empty missle shell. After taking him away, he helped raise him and later fought beside him. Now, Optimus didn't have the spark to tell Ironhide he was a Decepticon.

6. Beast wars AU/G1 AU

Beast wars Megatron was not the real Megatron, but that never stopped him from trying to be. Unfortunatly, his timing was alway horrible, no matter what Time machine or universe he was in.

Together, He, Scorponok, Waspanator and Terrasour break into Tarantulas's Lab after their Cybertronian Elementary Classes. Gearing up to go into the past to murder Optimus Prime, the four small children make a tiny mistake. They aren't in B.C anything, they wind up in 1983. Killing Optimus Prime while he's up and moving arout might be a little more difficult.

Not that Megatron, now dubbed Mega, woundn't like the challange. But Damn those are real guns.
