As far as the Tremors movies go, the one constant outside of the Graboids themselves has been heroic survivalist Burt Gummer (Michael Gross), who's spent that last few decades blasting the hell out of the subterranean beasts with guns, bombs, and whatever other weapons he can get his hands on. Burt may not be John McClane, but he's a reliable friend, and a man that can be counted on to get the job done, albeit not necessarily without hiccups.
With Tremors 6 headed to DVD, Blu-Ray, and Digital HD in just a few short weeks, Universal has provided us with this fun little recap video that looks back at the five previous films in the franchise. Hosted by Burt Gummer himself, the above video summarizes the plot of Tremors, Tremors 2: Aftershocks, Tremors 3: Back to Perfection, Tremors 4: The Legend Begins, and Tremors 5: Bloodlines. It also gives fans a reminder of all the badass graboid action they've seen so far, in anticipation of all the crowd-pleasing creature encounters sure to come in A Cold Day in Hell.
While casual Tremors fans will probably forever associate the term Graboid with the hulking sandworms featured in the original film, the Graboid species actually contains multiple subsets at this point. As detailed in the video above, Tremors 2 introduced the Shriekers, which are much smaller overall than standard Graboids, but no less dangerous. They are actually a Graboid's evolved form, and can reproduce asexually, creating more Shriekers. A Shrieker's life cycle eventually sees it evolve into an Ass Blaster, which - as the name implies - are able to launch themselves into the air as if they were equipped with a jet pack. Ass Blasters can lay Graboid eggs, which begins the cycle anew.
It isn't entirely clear if Tremors: A Cold Day in Hell introduces a new type of Graboid. That said, while the monster pictured above is clearly an Ass Blaster, it doesn't look exactly like the ones seen in prior films. Official synopses have hinted that the Graboids at the Arctic research base where Burt ends up at in Tremors 6 are being secretly weaponized, so it's definitely possible that the lovely creature above is the result of human experimentation. Either that, or the differences in its appearance are simply an adaptation to the cooler environment.
Tremors: A Cold Day in Hell attacks DVD, Blu-Ray, and Digital HD on May 1.
