I posted something before about it needing to be in new game ultra, and I know that he is SUPPOSED to show up in the crystal temple after the ultimas are defeated. I am just now getting around to testing it. It should take me about half an hour to beat the ultimas, and then I'll hunt down jake, and let you know what I find.
I am now embarrised to have to ask, since I put a lot of information on this earlier, but....I'm on New game Ultra, beaten the game, and still can't recruit Wolfgang. Can ANYONE tell me what I'm missing? I've done all the quests through league of perverts (I helped Mistress TNA take over). What the hell am I doing wrong?
EDIT* Ok, so I beat all the ultimas and still no Jake where I was told he was supposed to show up. I'm still hunting for him though.
EDIT AGAIN* OK! He is in the crystal sanctum, but him appearing has nothing to do with the ultimas at all, but with the achievments. You need to have 80-85 % of all of the achievments, and he, Saphira, and Tira show up where the white thing with the blue ball is. AND!!!!! Spoiler for the dialogue. In a past post, I gave a theory for why Jake dissapeared. I am happy to say that, While I was incorrect about WHO he was chasing, I was correct that he was chasing someone tail.
Jake "On my last adventure, I met this beautiful Anthro named Melody. I have been looking everywhere to find her again. Last time I saw her was in a place just like this."
Kai "You mean you turned your back on Opala and Farah, after saving them from Osira?"
So apparently, Kai has a major hatred for Jake because of this, and they fight.
EDIT FINAL TIME* Ok, I said before that the fight was started because of a hatred of Kai for Jake, BUT!!!! Kai confronts Jake,calls him out for being an ass, and Jake says, I saved Egypt, what did you do?. Kai responds, its not a compatition, but I saved all of Namaria, Egypt, and Opala said I have a bigger DICK! Jake then gets pissed and attacks you.
