After Jake acquired the Howler morph, why did he never try to morph the Howler again after he left the Iskoort Planet? When reading #26, it felt to me like K.A. Applegate made the Howlers seem pretty powerful. Even a single howler seemed very formidable. I mean, their howls were enough to incapacitate most people in the nearby vicinty. Also, their regenerative ability and acute mind that can pinpoint a living organism's weakness seemed like great traits to have in battle. Also, since one single Howler was able to take on all the Animorphs and Ax in that battle in the book, it only goes to show that the Howler morph is more powerful than Jake's tiger morph.
Can you imagine how different the series might have turned out? (I might be overstating the Howler's potential here.)
In close quarter battles, he could incapacitate most of his foes with his shrieks. He might have been able to catch Visser 3 off-guard and knock him unconscious with his howls before the Visser could morph. Then he might have been able to kandrona starve Esplin.
I mean, it is possible that Jake could just simply walk into the Yeerk Pool and continue howling and running around till everyone was on the ground unconscious or dead. (Though this would hurt innocent victims and thus would most likely not happen.) After all, what would Jake have to worry about? Any slashes from the Hork Bajir would just heal itself. (I am not sure what would happen if he got his head chopped off...but I would venture to say he would stay dead and not regenerate.) But even more so, he could have been the one to be aboard the Blade Ship in #54. A quick demorph and remorph and I am positive he, with his howls, could have taken out the yeerk troops that were with Tom. Then he could have either tried to land the ship or just bail and demorph and remorph to a bird in midair. If that happened, Rachel and even Tom might be alive. )
