Wendy (standing for Weakest Entity Not Destroyed (Yellow)) is currently the weakest entity known that has not yet been destroyed. She is extremely small (smaller than a Blueprint Particle), and has 2 brothers: Wendr (Weakest Entity Not Destroyed (Red)) and Wendb (Weakest Entity Not Destroyed (Blue)).
Dangers to Wendy
Anything made with Blueprint Particles and Blueprint Particles themselves are dangerous and deadly to Wendy (this includes photons), so taking photos of Wendy proved to be difficult. Even • is extremely dangerous and acts like antimatter to Wendy, and math has shown that the resulting reaction would be visible to the human eye.
Powers of Wendy
Because of this, Wendy has a means of self-defense from these particles. She says she has a 'particle forcefield' which can rebound particles, although it takes 'a lot of effort'. She is currently trying to make an easier way to do this. She also knows many languages and has a lot of conversations with her brothers.
Wendy has a house that she lives in that is located within The Final Void. It is currently unknown what it is composed of due to its size.
