Dr. Neil Watts is one of the two main playable protagonists of To The Moon, and is the primary playable character. He is an employee of Sigmund Corporation and partner of Dr. Eva Rosalene. His official title at the company is Technician Specialist. 

He is humorous and light-hearted, in contrast to Dr. Rosalene's character, and often makes jokes and various pop-culture references throughout the course of the game. Although he is often perceived as silly and childish, Neil is also very smart, and can be serious when situations call for it. Despite a callous attitude towards Johnny and River's lives early on, insisting on finishing the job and getting paid, he later vehemently opposes Eva's efforts to eliminate River from Johnny's memories, insisting that Johnny will not be happy. Neil's stance at this point switches with Eva's, with Neil attempting leave River in to make him happy, even if it means they cannot send him to the moon, while Eva seems to be trying to fulfil his wish regardless of whether or not it makes Johnny happy.
