This was actually one of the things I hated about the series.
Yes. I understand we can't kill off the Animorphs early in the series. Yes, I also understand they improve with time. I also understand new controllers will not be skilled in battle.
What gets me is that how a wolf will take down multiple eight foot tall bladed reptiles that can easily recover from most impalement-type wounds (when we see Jara Hamee cut into his head to prove he is not a controller).
I don't care how skilled you are, or if the controllers are drunk on top of being new. Some earth animals are not taking down eight foot tall bladed lizards armed with particle weapons by the dozen. It just doesn't happen. I don't care HOW amazing you are, how organized you are, or how lucky you are. It just won't happen. You can see amazing last stands throughout history where small numbers did amazing things, defeating countless enemies, only to be defeated by the sheer number of enemies. Look at the Battle of Thermopylae.
I feel Hork-Bajir controllers suffered just as much decay as Visser Three. They go from incredibly terrifying where equal numbers are almost death, to killing them endlessly with ease. Even Jake's Tiger and Rachel's Bear, the strongest morphs, still have significantly less natural weaponry, not to mention they are two creatures, fighting a multitude - it doesn't help that grizzlies aren't exactly the fastest animals on earth. Marco's gorilla... Yes, gorillas are strong and heavy, but no more than a Hork Bajir. Not to mention gorillas have no natural weapons and yet Marco easily kills many of them, even when being shot at. A wolf is about 80 pounds and has teeth, and Cassie had a female wolf, which is about 20% smaller than the males and have narrower shoulders.
It was just irritating how giant reptile-like creatures covered in blades who probably weigh a few hundred pounds and are strong enough and fast enough to rapidly swing through trees can be taken down in such mass... by earth creatures who are smaller, weaker and have far less natural weapons.
Skill can make up for that, if they were evenly matched. Not when it's 30 to 6. That should be a massacre, and not the way it happens in the books.
