A sense of power / run into everything

Hi again,

In the following passage, I need to figure out the meaning of the words underlined.

Any idea would be welcomed.

Thank you~

This is about wolverines.

Q1: "a sense of power"? does this mean its physical energy?

Q2: "run into everything in his path"? I can't picture the situation in my mind. If possible, would you explain it in other ways or more easily?

As a trapper, Tim wanted me to shoot him, but I refused, for this is the most
fascinating and little known of all our wonderful predators. His hunchback gait was awkward
and ungainly, lopsided yet tireless. He advanced through all types of terrain without change of
pace and with a sense of power that seemed indestructible. His course brought him directly to
us, and he did not notice our immobile figures until he was ten feet away. Obviously startled,
he rose up on his hind legs with paws outstretched and swayed from side to side like a bear
undecided whether to charge. Then he tried to make off at top speed and watch us over his
shoulder at the same time, running headlong into everything in his path.
