The elephantine bloat titans are swollen, 16' tall, 10 ton arachnids that prowl grasslands and forests in a neverending quest for fresh blood.  When a herd is on the move, the ground quakes and wildlife flees in terror.

A bloat titan's thick carapace is impervious to conventional melee weapons and firearms.  And its deadly jaws transmit Hyper-Lyme Disease upon a failed Saving Throw Versus Death, which acts as the Superflu virus [see p. 48 of the Mutant Future Core Rules] without the communicability aspect...and it lasts 1d2+2 weeks, instead of 2.

Bloat titans dislike open flames, and villages often deter the creatures with bonfires or burn-pits.

Mutations:  Gigantism, Toxic Weapon ("Hyper-Lyme Bite")
