The Skugs are Grimlords' foot soldiers. They usually take the form of human beings when carrying out Grimlord's agendas and travel in twos or threes. In human form, Skugs apparently gained more individuality and intelligence than they normally have in their true forms, as evidenced by Ziktor's secretaries and inventor Strickland. When confronted by the Troopers, they change into their true form and split into a few more to increase the difficulty against their adversaries. They can shift through solid floors back into Virtual Reality. There are a rare occasion of Skugs known as Mutant Skugs. Normally they are defeated by the fact that they evaporate if they touch each other. These characters are similar to the Putty Patrollers and Z Putty Patrollers.
The Skugs would later be upgraded to Ultra Skugs powered by Tyler Steele's technology. They begin as regular Skugs in traditional Trooper battles, but can transform to this form of drastically different warriors by posing towards one another in a fighting stance. They are significantly more difficult in this form, however they could still be eliminated the same way as the regular Skugs by knocking them against each other.
When JB and Kaitlin were on a mission to rescue the scientist kidnapped by Skullbot and the Skugs, one of the Skugs had a robot face underneath the Skug face. It was much stronger than a normal Skug. Before it even had a chance to attack him, JB managed to destroy it with his Laser Lance command.
- Due to their origins from Jikuu Senshi Spielban, the original model Skugs never fought against Ryan Steele in either of his VR Transformations, only in his human and battle grid modes. The Ultra Skugs, having originated from Uchuu Keiji Shaider, could only fight Ryan in his second VR Transformation, but not JB or Kaitlin in theirs.
- Rumor is that Grimlord's foot soldiers were originally going to be called Fyes, they found out that Fye is a real last name, so they changed the name to Skugs.
- Many have speculated that Skugs can only be defeated when they touch each other and have wondered why Grimlord never sent a single Skug, which would be invincible. This is FALSE. On multiple occasions, JB has finished off a platoon of Skugs with the laser lance, and in those instances the Skugs never touched each other.
