A Thoughtful Alien.

A pensive and ancient Alien - looks like a concept from the JW Creature Workshop.

The Perfect Guard

Saurian with the patience of a stone. Their home world  with it's harsh climate developed some of the best hunters in the galaxy. Strong, lithe, flexible bodies with nearly 360 degrees of movement for the neck and spine. They have a heightened sense of their environment. Their skin can pickup on atmospheric changes, temperature and even inaudible "Noise". They make great bodyguards and are naturals at ambush techniques. Long ago, there was consideration that they might be pisonic - but now we know they are just very quiet, very sensitive and very patient.

for smashing.

Large fists for smashing. and very well developed legs for holding up those fists.

Alien with head plates - not to be understimated

Most Alien life forms don't use their head as a weapon.

there have been plenty of animals that have horns and Antlers for display and ritualistic mating combat but a true offensive weapon that involves the skull? Very few indeed.

The Jah'wi have this trait. An articulated set of plates beginning just above the nostril flares and ending just before the thoracic vertebrae is the only signal that the Ja'Wi head is a formidable weapon. Originally thought to be decorative or defensive in nature these plates are actually diminutive when compared to the underlying skull and cervical vertebrae structure. Thick muscles around the neck and shoulders can compress the skull and neck by 20-25% and thrust forward at almost 35mph, Neolithic Jah'wi would use this strength to move, lift and build their massive inverted pyramids.

There is no evolutionary evidence to suggest they were anything other than the dominate, sentient Species on their planet. They have strong tradition going back eons of fantastic engineering feats for the resources of each age.
