Tsukune's no Smarter when hes in his Ghoul form, In a Straight one on one fight between Hulk Vs Moka or Tsukune, the hulk would win.
Plus the Hulk isn't stupid, watch the movie. Hes Cleaver ... or somethin, like when he did that sonic boom thing to put out the flames of the helecopter. And Spider man? pffft please

anyways I don't think Kokoa even likes Tsukune, I hope the others do for funnyness..
