Hal Jordan vs some shark guy in his solo series
If your referring to this Shark, I'm afraid I don't see the issue. He's a TPer, TKer, energy projector and one of his powers is to project fear (the known weakness of a GL ring). I men those powers are the same as most of GL's most dangerous foes ( Hector Hammond, Krona, Ultraa, Mongul, Starro, Despero, Amazo and many more)
you wouldn't believe the amount of jobbing Hal went into (a trained solider who was one of the first to damn overcome fear AND has capabilities to block pyschics from messing with his mind). Here's the link to the battle page i argued against shark's case.
1. Hal most definitely has not "overcome" fear. If he had Parallax would not have been able to possess him.
2. Hal and other GL's have succumbed to TP and TK many times - the reason I listed some of Hal's enemies who had it and had seriously troubled him with it)
3. I wasn't aware of the more recent showings, I was thinking of the SA Shark who was a matter/ energy manipulator because of how powerful his TK was. SA Shark was a beast.
