Kaibi used to live in a field when they were younger,it was rather quiet and peaceful there.They loved to play around with their sister all day long until nightfall.Unfortunately,at age 5 kaibi was taken away during their sleep and awoke to active tests on them.These tests damaged the evolution pattern and made kaibi end up evolving into something similar to stlveon at age 10.This has happened such a long time ago that this is only remembered as a dream and that she just was going to live in a forest until they found the group.The only thing remaining from the testing is a weird symbol on a foot
