Sokka always knew this day would come. Seriously, he's packed the basement with canned goods and other nonperishable foods. Besides that, I'm thinking the smithy will get raided a few days into the thing. He may get hurt when it happens. I'm not sure. But it means the NPCs will be well-armed!

Ling Yao will probably pass out from hunger at some point. Otherwise he has a more-than-full house and there's not a lot he can do to help people. So playing it by ear with him. He could be something of a problem due to how much food he can eat. So he may need some reprimanding.

Cyborg has powers that come from technology, so theoretically he shouldn't be affected as much by the shift. However, he'll run out of power because it will take more juice to get his usual results. So a day or two into the event will probably see him running out of power and shutting down. Even our electrical people in Luceti may have a difficult time keeping him charged.

Wolverine will have his healing factor virtually brought to a halt, since that full ten percent is going to be used just to keep him from getting sick from adamantium poisoning. So he won't even be able to use his claws without leaving holes in his hands in need of healing. So he'll be pretty much normal. As for what he'll be doing? Trying to keep the peace and break up fights. Yell at people who need yelling at.
