In regards to biology not stopping the changes, two question:
For Vegeta/Saiyans/others with high resistance to injury, do they keep this during the event, or are they now squishy/able to be hurt as if they were humans?

For Idia: Would this affect his hair and the glow to it at all? Asking in regards to if he will stand out like a beacon in the darkness due to it.

Also for Idia and his tech (though maybe something later for the actual event to answer), will his tech be able to read/communicate with whatever technology they will come up against in there?

Thank you!
