Although similar in appearance to a chimera, a gorgimera is a more
fearsome monster. This sterile hybrid has the hindquarters and head of
a gorgon; the forequarters and head of a lion; and the mid-body, wings,
and head of a red dragon. Only the lion parts have armor class 5. The
gorgimera can attack with its claws, bite with its lion head, butt with its
gorgon head, and bite with its dragon head. Additionally, the gorgon
head can breathe its petrifying breath twice per day (3" long x 1 " wide
base cone), while its dragon head can breathe its fiery breath twice per
day (5" long x 2" wide base cone). The monster will always use 1 of its
breath weapons against opponents 10 feet or more distant, as it is
aware of breath weapon ranges and effects. If in melee, there is a 1 in 6
chance it will use fire and a like chance it will use petrification (roll ld6,
1 = dragon breath; 2= gorgon breath; 3-6= standard attack routine).
Dragon breath is for 3-24 (3d8) points of damage; save vs. breath
weapon applies. Gorgon breath turns victims to stone unless their
saving throwsvs. petrification succeed. Gorgimerae speaka very limited
form of red dragon language. The gorgon head can see into the Astal and
Ethereal Planes, and its breath weapon extends therein.

A gorgimera looks almost exactly the same as a chimera, except its
gorgon parts are a metallic biue color. Gorgon eyes are a red-rimmed
pale blue.
