Wind buffeted Optimus Prime's vehicular form as the LAAT/c transport made its way towards the battlefield. Explosions began to erupt around the craft, as the enemy began to notice the craft carrying him to the war below. They had passed the front line, and were currently over the enemy controlled portion of the battlefield. His hope was to land somewhere he wouldn't have to worry about crushing his allies.
"Prime! Flaks gettin' heavy, I'll need to turn back soon. You ready?" As the human spoke to him, the craft shook from an explosive burst that was unnervingly close. Although there was no significant damage, it foreshadowed a fate neither wished to occur. The longer the lone craft flew so close to the fighting, the odds would steadily grow in favor of the vehicle being shot down.
"It will have to do. There is no need endanger yourself unnecessarily for my sake!" he replied, preparing himself for an airdrop from a significant height. He would not have the blood of his human escort on his hands.
The magnetic clamps promptly disengaged from his metal chassis, and the craft began to pull away from him as he dropped towards the battle. His vehicular form started to change in ways most wouldn't believe it should move. In a matter of seconds, Optimus had transformed into his true form.
A few small parachutes erupted from an area on his back, slowing his fall as he rapidly approached the ground. Fortunately, the enemy forces did not seem to notice his approach until he was much closer to the surface. As small arms fire began to pepper him, he cut the strings of the parachutes and free-fell the remaining distance.
He landed atop some unfortunate Stormtroopers, and his massive size quickly reduced them to little more than a smear. Although he swore never to harm humans, the conflict involving the multiverse had made keeping his vow much harder. It was no longer a conflict involving Cybertronians and humans, Autobots and Decepticons. Things that were once clear were no longer. His enemy now was a collective of different races and factions from across the multiverse, many of whom seemed to have little to no regard for the rights of others.
Activating his twin arm cannons, he began to return fire. Many of his weaker opponents were easily blown in half by the blasts, while others took longer to take down. His pinpoint aim quickly found their weak spots, particularly their knees or necks. As the bodies piled up, the desert sand was quickly stained red.
He was surrounded on all sides, and the enemy forces were using this to their advantage. For every foe he cut down, be they demon, cyborg, or some other form of creature, two more replaced them. It was a battle even he could not sustain forever. The longer he engaged the enemy forces from his current position, the more stronger opponents would head his way. It would culminate in him fighting several high powered enemies, and force him into a situation he likely would not come out on top of. Transforming into his truck form, he began to plow his way through the enemy towards his allies. Applying more speed, he quickly surpassed the normal capabilities of his alternate form.
