Predator 2 Novel 10

The Predator lifted the emergency respirator,
pressed it up against its face, and inhaled deeply.
The supply in the reservoir would not last long.
Without its helmet, its only hope of avoiding slow
and painful suffocation was to reach the ship.
It felt strength returning as the life-giving gas
flowed, and the pain of its wounds began to ebb.
It had not failed yet. It could reach the ship,
recover, and then avenge itself upon that human
who had deprived it of a hand.

Once it reached the homeworld, a new hand could be grown and grafted on, but there was no going back until that human's skull and spine were nestled in the trophy case. If the reservoir in the respirator only held out long enough to enable it to reach the ship, it could treat its wounds, get another helmet, and come back to finish the hunt. But there was no time to lose. It had to reach the ship at once.-pg.220 chpt.8
