Simon

"It was Simon and Hypatia causing trouble. I tell you, Simon has been an absolute handful lately. I mean, more than usual. I'm confining him to his room and we can figure out what to do with him in the morning."

- Nevsky in an email

"Simon" was the name given to one of the gorilla test subjects at the Horizon Lunar Colony. His official designation was Specimen 9.

After being subjected to genetic modification, Simon was among the gorillas that began showing beligerance towards their human overseers. He developed a following of sorts with "fellow troublemakers," including Hypatia. One night, Patel complained of noises in the break room. Nevsky discovered that Simon and his gang were behind it, and thus confined Simon and his fellows to their quarters. This prompted Nevskey to suggest that all the test subjects likewise be confined, so that the test subjects wouldn't take their actions as favouratism.

Not long afterwards, the gorillas launched an uprising, killing the staff and taking the colony as their own.

Years later, Lucheng Interstellar was able to retrieve information from Horizon's still-operating monitoring system. Simon was noted to still be in the colony.
