The worst part of the story was Necalli. Other than that, I loved it.
Yep, he was the ultimate loaded gun that never fired imo, and as such he felt utterly pointless and almost like his fully separate storyline at best just happened to coincide with those of the others instead of actually intertwining with them and taking place within the same plot arc.
Some spoilers: I mean he could have been used to weaken
Bison or to absorb his increased psycho powers so others could have a chance finish him off, or he could have been used as a plot device to finally rid Ryu of his dark hadou (by absorbing only that part of his soul, perhaps due to Dhalsim stepping in or something). Heck, he could have become the actual biggest threat after consuming both the dark hadou and Bison's power, thereby forcing everyone to work together to fend him off (after which Bison could do a heelturn and Nash could still enact his revenge) but alas, he mostly just appeared and went away multiple times without really devouring anyone's soul.
Granted, I did like his appearance as a sheep during Nash's dream sequence(?) at the beginning (
even if this also never amounted to anything with regards to him curing Nash or destroying him etc.
