Tarrasque
The tarrasque is one of the most terrifying creatures of nearly any plane. Their origins are not completely known or understood. It is believed that these creatures lie dormant for centuries or even millennia only seeming to rise during great cosmic events. Some believe these creatures are heralds of destruction called forth for divine judgment by entities with seemingly limitless powers.
Accounts from long lost lore seem to suggest that the tarrasque has multiple forms or at least multiple incarnations, each form seems to correspond for its destructive intent. Regardless of which account is accurate, the arrival of a tarrasque spells immediate doom for the denizens of that plane. These entities are living apocalypses in their own right as their sheer power rivals that powerful being such as celestials, demon lords, and liches. These creatures leaves a swathe of carnage and destruction in its wake destroying or consuming everything in its path. Once its appetie for destruction is sated, it returns to its lair to return to its eternal slumber until it is called again.
Tarrasque Tactics
A tarrasque is more akin to a force of nature rather than that of a creature. It mere presence invokes mortal terror into creatures while it seeks out and consumes the largest source of sustenance. Most forms of attacks are nothing more than an annoyance to it wherein it proceeds to use its breath attack to annihilate any pesky attackers. If a attacker poses a true threat to it, it seeks to quickly eliminate that threat by either swallowing it in its colossal maw or annihilating it with its immense strength.
The magical presence of these creatures actually warps its surrounding to conditions more suitable for the tarrasque. This makes it so much more dangerous as many of these alterations can be quite destructive.
If the resistance against the tarrasque proves to be too much for it, it begins to transform into a primeval state in its fury causing it to become much more powerful and dangerous. This state acts as a defensive mechanism providing it the opportunity finish off this threat or to retreat to safety.
Spellbane Tarrasque
All accounts of the spellbane tarrasque seem to be associated with periods of extreme arcane activity. Some believe these creatures are an extension of divine judgment for arcane hubris; others believe that large surges of magic simply awakens these creatures from their slumber. Regardless of why it was awoken, this creature is has evolved specifically to consume arcane. Its body seems to act like a mana sink that absorbs the magical aether from its surroundings. Whenever it uses its breath attacks, it actually consumes an annihilated arcane energy causing it to detonate in a magical discharge. This arcane imbalance is also believed to generate sporatic zones of antimagic as well as wild magic miles from the tarrasque's location.
Godeater Tarrasque
This variant of the tarrasque is believed to be the universal balance between good and evil in the multiverse. Whenever the tides of either seem to tip overwhelmingly in the favor of one side, the appearance of a godeater was never to far behind wreaking devastating in both the Upper and Lower planes. However some accounts seem to suggest that these creatures were purposefully awakened by cultists or divine orders in an ill-founded attempt to annihilated the forces of good or evil. However, due to the untamable nature of the godeater, this only resulted in widespread death and destruction.
Undying Tarrasque
This variant of the tarrasque is the result of the unfortunate event wherein a powerful lich or similar undead manage to reanimate the corpse of an dead tarrasque. The necromantic energies that give it new life further fuels its appetite for destruction, especially for that of living things. Due to the monumental power of its lifeforce, it is largely unaffected by many weakness that the undead possess instead amplifyinh its undead essence. The path of carnage and destruction forged by this creature actually creates more hungering undead following its wake. The arrival of this creature certainly spells doom for all living creatures on that plane.
Star Eater Tarrasque
This variant of tarrasque is certainly the most rare of its kind. In its quest to sate its hunger, it is possible that a tarrasque finds itself in the Far Realm, it begins to evolve and transform into something truly unimaginable. Its exposure to the Far Realm gives its mind-breaking psionic abilities sowing mass insanity and madness to any creature unfortunate to cross its path. When angered, its psionic abilities have the potential to rend reality itself causing portions of the Far Realm to bleed into reality.
