Choose a character (characters will have descriptions on their personality and sometimes will have photos of how they look, if they don’t then they will have a description)

Then choose what they should test out, it can be anything such as alien devices or plants or even let them meet an alien.

(You can add aliens from other media same with devices and plants)

(I still don’t know if characters from media will be allowed to be used as test subjects but maybe)

Some characters will be male or female.

(Note - if you want to do a story then feel completely free to do so)
