Hasn't Aquaman had fights that he doesn't automatically resort to his Telepathy? I'd think that if he didn't use it that this would be a great fight. Also to say that his TP would be an auto win 100 percent of the time is not correct.
If it was Arthur would have a spotless records chock full of wins, and they would call on Aquaman and not Superman when the S&8t hit the fan.
Namor isn't a pushover, and Hawnman is pretty tough himself.
