Nack the Weasel (Sonic the Comic)

Nack the Weasel is a version of Fang the Sniper from Sonic the Comic, and appears as a recurring antagonist of various characters, particularly Chaotix (a group of which he was once a member).

History
Nack used to be a member of the Chaotix Crew, serving as one of the guardians of his native Special Zone. However, he betrayed the Chaotix to the Brotherhood of Metallix for money, first by giving the Brotherhood access to the Omni-Viewer's system and then leading the other members of Chaotix (as well as Knuckles) into a trap. However, when the Metallix felt that they had no further use for him, they betrayed him in turn. He had expected this, however, and come prepared with a disruptor gun with the power to destroy all of them. Unfortunately, he was blasted in the back before he could use it (Knuckles later took and used it instead), and spent the next few months in a prison hospital. He broke out and appeared sporadically throughout the comic, working solely for financial gain either through mercenary work or robbing banks/ancient treasures, and he twice battled the Chaotix.

He finally teamed up with Robotnik's loyal lackey Grimer, developing a belt-like device that could shrink people down to sub-molecular levels. It is never officially stated why he did this, but it is assumed he was paid, or promised payment, by Grimer. Using this, he and Grimer intended to retrieve Robotnik (who had been shrunken to these levels and was presumed dead); in the process, they came across the sub-molecular, mystical world of Shanazar. Nack would eventually help Robotnik not only return to Mobius but also merge it with Shanazar in the process, after which he was never seen again.

Oddly, after having such a crucial role in starting the Shanazar run of stories, Nack never really had much of a role in those stories. Nigel Kitching revealed on the sonicthecomic Yahoo group that he originally planned to have Sonic chase after Nack through Shanazar so he could use his belt device to return to Mobius, but he was fired off the comic before that could happen (he was rehired by a later editor).

Characteristics
His character was said to be a scientific genius, as shown with his development of the disruptor and knowledge of how to hack the Omni-Viewer. He also had an affinity for shrinking technology, such as his shrink ray and shrinking gas cartridges, which allowed him to shrink and grow objects and people, including himself.

He used this technology to conceal weapons, as well to shrink down echidna treasures from the Sandopolis Zone so he could more easily steal them and then re-expand them before hopefully selling them on. He also used this technology during combat.

Sonic the Comic Online
In the unofficial online continuation of Sonic the Comic, Nack reappeared going on a crime spree across the city, with Tails hot on his trail. After constantly remaining one step ahead of the cops and also nearly killing Tails with a bomb, Nack was finally brought down when Tails caused his getaway plane to crash into a river. Though no body was found, he was presumed dead. In actuality, he survived. After vowing revenge on Tails, he decided to lay low for a while.
