How many doctors died in Apocalypse IV?

None of the four Apocalypse doctors are dead.

Dr. Apocalypse IV is the collective name of four doctors in the SCP Foundation series of Overhead Worldview, namely, Dr. Clef, Dr. Kondraki, Dr. Gears and Dr. Bright. The four people correspond to plague, war, famine and death in the four horsemen of the apocalypse.

The true face of p>Clef can't be clearly photographed by any known method, but it looks like a big nose and a big grin similar to that of Cheshire cat. The only known sample was photographed by [data deletion] in Liddel operation room. He has three green, blue and hazel eyes. These eyes all seem to have pupils that can absorb all the light falling on them. It is known that the entity will act as a deep-rooted liar in everything except SCP-related issues, so no one should trust it.

Dr. p>Kondraki is an SCP researcher working in Site-17, and also a scientist and photographer of the Foundation. When he is not working in Site-17, he usually develops new optical technology and upgrades his camera for a long time. Although he has no education in these two fields, he seems to have done quite well in self-study.

Gears is an ordinary person and has not been polluted by any SCP project so far. However, there are some significant differences between him and ordinary people, mainly in the form of emotional response. Gears seems unable to respond to any external stimuli in an emotional way, with few exceptions. In addition, he seems to lack the ability of startle reflex and the basic form of "fight or flight" reaction. Such as [data deletion]. Despite internal bleeding and partial blindness, Gears calmly requested to complete the experiment and walked to the medical treatment room on his own after half an hour.

Dr. p>Bright has reached the pinnacle in the fields of bioengineering and abnormal genes. The foundation took in his brother SCP-59 and recruited him as a staff member. He was assigned the research work of SCP-963, because of which he died and was resurrected. Since then, it has played an important role in several SCP studies and assisted in more precise experiments of SCP.
