Ollie is just the average teen. 
However, he has a couple triggers. These are:
Blood
Anything that reminds him of Ollie.EXE or exe's in general (like wikis or newspapers)

If these criterias are met, Ollie will lose control and become Ollie.EXE through a painful process of grabbing his head and trying to stop it, to no avail.
Ollie.EXE has red irises and black scleras, and has high murderous tendencies.

The only way to revert it is by showing him BFDI or FNF in any shape or form.
