Theory: there are not several species of Grimm, there is only one. They all start as one type of Grimm and eventually they evolve into other types.

For example, let's say that all Grimm start as Beowolves, as time goes by they grow stronger until they become Alphas, then they evolve into the next type of Grimm.

That would explain the Goliaths. The Goliaths that we saw were patient and smart, they were waiting for the right opportunity to attack, unlike the other types of Grimm that we saw that just kill any human in sight.

The main difference between the Goliaths and the other Grimms was age. Those Goliaths were ''old. ''I imagine that at some point, the Grimm that lived for long enough become Goliaths, and they just keep evolving into different species.

I think that the last type of Grimm will either by a Dragon Grimm like the one we saw, a Human Grimm (Salem?), or something else entirely.
