They’re just pigs but more evil in every way possible with the exception of riding them. Normal pigs hate people riding them, but these guys don’t even mind an uncomfortable saddle and a human at the same time.
This here hog can "clear the savanna after every meal", it will however, be quite a large meal indeed. Also breed them so when you have a baby you can scream "WHEN HE WAS A YOUNG WARTHOG!"
Tame a male daeodon, name it pumba, tame a jerboa, name it Timon (just pretend it’s a meerkat), tame a male and female saber-tooth, breed them, name the baby Simba, now you have re-created the lion king
