Logos Reaction Factor Edit
Startup - Good to great. People that are scared of THX may be scared of the startup, and the logos reaction factor may increase for them, like Serena's Eevee And Serena's Sylveon. However it sounds awesome!
Shutdown - OK. Not too freaky, it's also unknown on the CLG Wiki.
