In principle, Autobots did not possess the ability to fly.
Even Starscream, who transformed from a supersonic fighter jet, had to land on the ground when switching forms.
And that was one weakness behind their immense power.
Otherwise, why would Optimus Prime and the others try to drag those elemental envoys down to the ground instead of flying up to beat them?
Likewise, First Aid had no way to fly directly into mid-air and catch Xiao Tianyang as he fell toward the ground.
However, the battlefield's rugged terrain gave him plenty of room to maneuver.
On a slope, First Aid suddenly pushed his speed to the limit!
Then, with a roar, the ambulance he had transformed into launched straight into the air!
He transformed in mid-air, switching back into robot form, then curled his body around Xiao Tianyang as he fell!
At the same time, he immediately switched back into ambulance form and landed safely!
However, just as First Aid let out a sigh of relief, he was startled halfway through examining Xiao Tianyang's condition.
"How is he this badly injured? His life is hanging by a thread!"
The red light atop First Aid's head began flashing frantically.
Clearly, Xiao Tianyang's condition had reached a point beyond his ability to handle.
Of course, he did not turn around to ask Optimus Prime what to do.
Every Autobot was an independent individual with a distinct personality, not an appendage of Optimus Prime.
No matter whom he treated or what field he specialized in, he was a healer at heart.
Xiao Tianyang's injuries were extremely severe. Since he could not handle them himself, calling Optimus Prime would be useless as well.
The best option was to let the humans treat one of their own.
And the best candidate for that was Saber!
