OK, now I just need a power weakness and character weakness.

With Pete I had him suicidal and emotional, with a very uncontrollable power set

I guess with this power comes issues of personal space and boundaries, and every time The OV is used, he has to temporarily shut down another sense, which itself comes with baggage. (No sense of touch means he cant feel emotionally involved, no sense of taste he tells the truth with anything, no hearing he becomes an impulsive, womanizing asshole, ect)
