However, in the following books, despite being in countless battles, Jake keeps using various Earth-animals as his battle morphs. But the Howler could have been very useful.
I can think of a few reasons.
- Jake actually did not get to keep his Howler morph. That would be the first time a morph has disappeared (except for Sario Rips and allergies, neither of which applies here.) If he didn't get to keep it, then why? Well, maybe:
A: All the Howlers were ultimately destroyed, so maybe the Howler DNA in Jake's blood was also destroyed due to the same cause?
B: Since the acquiring happened during some sort of "chess game" between Crayak and the Ellimist, maybe there was some sort of rule that said they wouldn't keep morphs or other acquired things?
This is just speculation, though. So, why?
- The morph was so terribly scary that Jake didn't want to use it. I guess it's possible, but given all the terribly dangerous battles Jake was involved in, it would seem senseless not to use such a powerful morph.
