Slick Terror

Slick Terror is a giant scorpion who is Blake Von Jaeger's second in command, and the most loyal to him. He has potent venom that allows him to turn the innocent into heartless monsters. Slick Terror has antibodies that protect him from the effects of his own venom. He is a recurring antagonist, debuting in Icy Shadows 2 until his death in Icy Shadows 7.

Only those people whose hearts are strong in mind, body and spirit are immune to the effects of his venom.

In Icy Shadows 5, he injects his venom into the last seven of the ten Heartless Kings, turning them into mindless monsters that only follow Blake's order (or another Axis of Legion member). However, all of them are cured of the venom thanks to Marisol and Marie working together healing them of their sins.

In Icy Shadows 7, he is slain by Sully X-29, as part of the latter's redemption quest. He eventually returns to dust.

Backstory
During his time with Blake Von Jaeger, they found three fathers who had problems.

Personality
He loves filling innocent people with fear and terror, and revels at kicking weak people when they are down while he laughs sadistically. He loves making people suffer, showing no remorse for his actions.

He is a powerful opponent who can defeat an army of Ice Pikers just by swinging his claws.

Later on, it is revealed in Icy Shadows 6 that he played a role in corrupting the parents of Ty, Jarrod, and Brock.

Venom
The venom of Slick Terror causes victim (s) to cross into despair and then lashing out their innermost rage at innocent people. The victim will be no longer in control of his/her mind, and will become a monster that will attack anyone in sight like a mindless monster.

Trivia

 * Slick Terror's manipulation parallels that of a false prophet - he lies to people about fixing their problems, which in turn causes sin to spread across their families. He has the muscle to back up his manipulative speech.
 * Remember Joyce Carol Oates character called "Arnold Friend". Removing r's causes the phrase "An old fiend", or in other words, A(r)nold F(r)iend.  This same concept can be applied to Slick Terror - he's your great f(r)iend Slick Terror.
