Obadiah kept accelerating.
Tony Stark's arc reactor was running out of power. Like Ultraman's warning light flashing red, Tony slowed more and more.
But then Obadiah noticed that he was slowing down too.
If he could have seen outside, he would have realized his Iron Monger was icing over.
"What's going on?"
Obadiah suddenly found that his armor had stopped.
Tony Stark said, "Uncle Stane, did you ever figure out how to keep it from freezing?"
Clang!
Tony gave the armor a tap, and the Iron Monger plummeted even faster than it had climbed.
Obadiah Stane frantically tried to reboot the system, but it was already frozen.
All he could do was keep hammering the controls.
On the ground, Li Wei and the others saw the Iron Monger falling from the sky.

"Get over there, quick!"
Li Wei shouted at once.
Quicksilver didn't need to step on the gas. Bumblebee surged forward on his own.
But Quicksilver had to keep his hands on the wheel and pretend he was driving.
They couldn't let anyone discover what was special about Bumblebee.
Boom!
They had barely drawn close when they heard the Iron Monger slam into a factory building.
This time, Stark Industries' factory took the hit.
S.H.I.E.L.D. agents rushed over and sealed off the area.

Obadiah was furious. The Iron Monger's targeting system had broken in the fall.
Without a targeting reticle, he couldn't fire.
"Obadiah!"
Li Wei walked in and said, "You've lost."
"You
