3. Ghost
As battle raged across Detroit two mechs sat atop Sumdac Tower and attempted to gather enough allspark shards to protect their friends and the people of Detroit. Unbeknownst to them they were being observed; two mechs watched the scene with worry and fear in their optics. The taller of the pair was black and white with sweeping doorwings and a red chevron, the shorter was silver in coloration with headfins and a bright blue visor. Both were transparent and hovered a few feet above the ground. "They ain't gonna get enough, are they?" the silver mech queried worriedly. "I doubt it," replied the black and white. "We gotta do something," the silver mech stated, "I assume you have a plan?" "I do," the black and white agreed, "but I will need your help to pull this off." When his only reply was a cheeky grin the mech continued, "The extra energy the allspark will need to form the shield will need to be provided by one of us as the energy drain would kill either one of them, our young prime will most likely need to be rescued as he will likely be within the formed shield. Which do you want?" The silver mech consider the options briefly before replying, "I'm better at interacting with the living, so I'll save Prime's aft. Just be careful up here, 'kay?" The black and white mech nodded before returning his attention to the two living mechs, seeing one of them begin to glow he spoke, "It's time." The silver mech darted off the tower toward the two dueling mechs as the black and white rose up to place himself between the shards of the allspark and the now levitating black and gold ninja.
When Prowl couldn't reach anymore shards he knew what he had to do to complete the shield, in levitating up to allspark he was prepared to make the ultimate sacrifice. He had just started the process the something interposed itself between him and the glowing crystal. Prowl caught a glimpse of a mech before a fist connected with his chestplate, breaking his concentration and sending him flying. Jazz reflexes were fast enough that he was able to catch Prowl before he cleared the edge of Sumdac Tower and the two mechs watched in awe as the allspark emitted a powerful beam of light that surrounded the final clone.
Optimus was overjoyed when the clone was surrounded in the allspark generated shield. He was less than thrilled however at being inside said shield along with Megatron himself. When Megatron pressed him against the shield with the intention of taking him down too, Optimus felt the end was near. What he didn't expect was to feel a pair of hands grab his shoulders then find himself teleported near the ground outside the shield in time to watch the clone blow. As soon as his feet touched the ground Optimus spun around, and managed to catch a brief look at his savior before the mech vanished. He didn't get a chance to wonder as the rest of his team arrived. All but Prowl were shocked at his story, and Prowl was cajoled into telling his tale. Ratchet cautioned them both against looking for mechs who in all likelihood didn't exist before herding them back to base.
The two ghostly mechs watched the fuss before the silver mech asked "Ya' think they'll have better luck then we did?" The black and white simply smiled.
