still the speed of bullet can't be whistanded by creature because organs and bones are so fragile to bear so yeah a creature best bet it having at least bare minimum of both to engage in combat or use the classic strategy aka run away
a fine example of this is the cheetah despite being the fastest animal in the world he can't take most large animals and prey on with low intelligence and lack power
that's why he can't win against a hippo and lion who has the bare minimum of speed and and big power
unless he had gather bunch of his comrades against one of them
an extreme example of brute force with low speed is the elephant that rarely get preyed by anyone outside humans because his brute force and big mass cover up for his lack of speed because he a creature can perfectly became strong without giving up on many things actually some of the ancient creatures were really bigs with strong power and not giving up on speed but they got eradicated because their body required a lot of food and they weren't that many
but the thing with speed is that you are doomed if you rely on it alone without big strategic moves and choosing you time of preys
since it doesn't protect you against a creature able to defend itself since you have to give up on power for it
