Jacob choose his Dad. He clicked him and brought up the screen to see what he could do to his dad. the list showed him that he could change his gender, his appearance, his race, his mentally (the way he thinks), and his past. He checked the gender and saw man, woman, and futa. He checked appearance and saw he can make his dad look like anyone, there was a warning saying that if he makes changes without checking the box beside the warning his appearance will change as well. race was apparent. Mentally showed that he can have him do things he would normally not do or stop doing some of things he can do. Like race/specie changing his past was apparent and he could have done anything he would have like him to have done in the past.
