Smilodon

Smilodon, is an extinct family in cats, containing the "saber-toothed" cats. The highlight was two extremely long canine teeth. Smilodon's predecessor was Machairodus, who did not get any other famous successor.

Description
The Smilodon is way superior to the Alien and makes it useless. However Doggie doesn't want to remove it so the Alien got a different role.
