Lord Slug easily.

Is Turles was first shown in the 3rd movie, while lord slug the 4th. It is clearly stated that Goku that he never felt "that type of energy" when facing Slug. Movie 3 and Movie 4 are in the same timeline, if you take into account that when Slug reads Bulma's mind the scene of The Tree of Might where she, Krillin and Gohan summon Shenron to restore the forest is shown.

So yea.
