Gilles' Sea Demon
This gigantic monstrosity is reminiscent of the Star Spawn of Cthulhu.
It is horrifying for ordinary people to see it - they must make a Fear Save 
against the creatures' APP -20. If they fail, they not only freak out in a way
the Storyteller chooses, they must also gain a Madness Point. This is in addition to
any other Madness Points the victims gain from encountering the monster.  

STR 20 	CON 19 	PER 6 
DEX 2  	INT 1  WILL 6

Perks: Armor 5, Combat Reflexes 2, Magic Circuit 5 (only for the purposes of resisting spells), 
	Regeneration (20 Life Points Every Round), 
Flaws: Gigantic Size (+4 to attacks against it) 

Actions 1	Initiative 10	Luck 2
 	Fear Save N/A	Movement 11

Life Points 166, Mana 42

Skills
Alertness 5, Brawl 16, Dodge 18

Attacks
Absorb -, damage death  
Claw 18, 1D6 x STR Lethal 
Tentacles (4 attacks/round) 9, does STR in Bashing damage or holds for Absorb 

Notes: Due to the creature's large size, slashing a tentacle doesn't do much harm to it. The only way to really harm it is to do a massive amount of damage to the main body. An Anti-Fortress or Anti-World Noble Phantasm would do the trick.
