tf_bunny_farm | For Halloween

1) Strange sightings of transparent giants make Detroit panic in the night of Halloween. Upon investigating, the Autobots see a shadow running around who leaves blue blurrs behind, whispering so fast you can't understand and meet a figure which the humans call "a clawed demon with wings and red-glowing eyes". And then there's the last apparition, a warrior with kind blue optics and a sad smile etched on his face for his friends...

2) Space barnacles have mutated and affect now also humans.

3) Lockdown is back on Earth - and he has set his optics on four special bots: Jazz (fellow ninjabot of Prowl), Ratchet (gave him one of his biggest defeats and is also an escaped prey), Arcee (same as with Ratchet) and Optimus (same as the two before, with new bounty on his head).

4) Prowl is alive again. Unlike Optimus, however, it was a torturous process, making him almost unable to deal with the fact he is alive.
a) Unicorn wanted to devour his spark and Optimus, unwilling to let his friend vanish into complete nonexistence, pulled him back with his own spark.
b) And died instead.

I wonder that I'm the first one for Halloween prompts.
