Frightful Fridays! Aggressisaur

Hello and welcome back to a new Frightful Fridays! GenCon fatigue will not keep me from posting a new monster, and this one is courtesy of Paizo friend, Mac. I like the idea of a creature that destroys lesser predators, seemingly saving the day, but really just enjoying sweeping out competition so it can freely attack its prey. And, yes, this one may also have been inspired by a recent movie.

In Frightful Fridays-related news, I'm finding that I have an incredible backlog of illustrations to process, and I have a feeling that a marathon is due before the end of the year. Stay tuned for that.

In Pathfinder RPG-related news, I would be remiss in not pointing out that this year's RPG Superstar has already begun! The deadline for entries is August 17th. Check it out here: http://paizo.com/rpgsuperstar. Good luck to all who decide to enter!

I hope you enjoy the aggressisaur, and I'll be back next time with another monster. Thanks for reading!

SPECIAL ABILITIES

Enraged Mind (Su) An aggressisaur is immune to mind-affecting spells and effects. However, it must still attempt a Will save when targeted by such spells and effects. If it fails its save, it immediately enters into a rage. It gains +2 Constitution and +2 Strength, but it takes a –2 penalty to AC. The rage lasts for the duration of combat or 1 minute, whichever is shorter.

Multibite (Ex) An aggressisaur can bite multiple times per round. It gains iterative attacks with its bite attack.

Powerful Bite (Ex) An aggressisaur adds twice its Strength modifier for its bite attack, and its bite’s critical threat range increases to 18–20.

Ship Crusher (Ex) An aggressisaur's bite ignores 10 points of hardness and 10 points of DR bypassed by a special material.

Created by dread krakens, aggressisaurs derive from mosasaur stock with a perhaps unnecessary amount of belligerence bred in. Ironically, the manipulation done by the dread krakens renders their creations immune to mental control, and any attempt to exert such control over aggressisaurs results in rage directed at the intended controller. These dinosaurs are virtual juggernauts of the sea and typically attack large creatures and vessels first before consuming smaller items, such as unfortunate survivors of a destroyed ship. Fortunately, aggressisaurs thrive primarily in the deeps where they have plenty of large prey to hunt.

In areas where multiple aggressisaurs roam, they quickly depopulate the sea and eventually turn on each other. Aggressisaurs driven by extreme hunger will launch themselves onto land near populated seashore areas. Their incredible stamina allows them to survive on land long enough to destroy whole towns—incidentally sating their hunger—and then return to the sea.
