What happens to the fallen in transformers?

Answer 1

Sam Witwicky revived Optimus, and Jetfire was nice and gave Optimus his own parts.

Then, Optimus flew up to the pyramid and destroyed The Sun Harvester, which created a shockwave which blew them all off the pyramid. Megatron fell down one side, and Optimus and The Fallen fell down the other. Optimus and The Fallen collided and then Megatron jumped over to join the battle, and Megtron sent The Fallen, by accident, flying into a wall. Megatron got a few shots at Optimus, but then Optimus grabbed Megatron arm and ripped a few pieces off, and then Optimus made Megatron shoot himself in the face. With a quarter of his face torn off, Megatron got up, but was too slow. Optimus spinned Megatron round, and blasted him, which sent him flying, and his arm came off. When Megatron finally hit the ground, his tank tracks were ripped and torn and broken. Unable to get up, Megatron called out, "Starscream!" but he didn't come. Meanwhile, The Fallen hadn't given up. He jumped on Optimus, and ripped one of his wings off (wings from Jetfire). Optimus grabbed The Fallen, and shoved him against a wall. The Fallen grabbed his special staff, but Optimus then snatched it off him. He shoved it through The Fallen's face and said, "you picked the wrong planet".

And with the special staff, Optimus ripped The Fallen's mask off and shoved his hand through The Fallen's body, and ripped out The Fallen's spark. Then Optimus said, "I rise, you fall". Optimus let The Fallen's body fall to the ground, and that was the end of The Fallen.
