Sentinel

Sentinel is a being of energy created by Solst.

Biography
Sentinel is a being of strange symbiotic energy. He is generally of low intelligence and a lot of the time has the mental state of a small child. Sentinel typically only listens to the orders of Solst himself, sometimes Raksen simply because of his authority and power. Other than that he's very unpredictable and tends to sneak around pulling pranks on unfortunate passerbys. Around others he typically acts innocent, sometimes to hide the sort of shenanigans he may be up to.

History
During Solst's brief period after leaving the Assassins and before he joined the Elite, Solst managed to tap into a significant amount of energy, accidentally manifesting a Construct because of this. He called him Sentinel and has since joined along with Solst in his escapades.

Primary Power and Abilities

 * Fluid Body: Sentinel's body is made of passive energy in the form of an oozy liquid.  He can turn into a puddle and shape his body into many things that are the same size or smaller than him, but always maintains the appearance of green ooze.
 * Symbiosis: Sentinel is able to absorb energies that are channeled into him from others.  His passive energy reacts with the power channeled into him, and takes shape.  One of Solst's favorites is to channel his fire abilities into Sentinel, turning him into a blazing white fire elemental.  Depending on the particular powers channeled into him, as well as the amount, Sentinel is given additional abilities that he can control for a few minutes.

Weaknesses

 * While the state of his body causes him to shrug off most physical attacks by simply regenerating the part that was hit, or even shifting his mass to avoid the attack completely, his heart-core is very vulnerable to direct assaults and is often hard for him to defend.  He is especially prone to sharp weaponry or bullets, which his normal fluid body is very ineffective at blocking.
 * If Sentinel's core ever takes too much damage, his entire body crystalizes into a small emerald around the core to protect it while it regenerates (which can take quite a long time).  This puts him out of commission entirely, and if the gem is left unguarded, a single strong blow could destroy him for good.
