Nack the Weasel

One of Nack's greatest accomplishments was when he captured Sonic, which led to roboticization, but escaped custody to hunt Nack down. He was found in the Bottom of the Barrel Bar 'n' Grill and later captured. Later, he and his sister were charged with capturing the Chaos-charged Knuckles the Echidna. After succeeding and collecting their payment, they separated, and Nack was not heard from for some time. He later appeared with a trio of nameless weasel "brothers"-later revealed to be named Carl, Jeff, and Konor, who planned to kidnap Princess Sally Acorn and collect a ransom from her parents, but Sally escaped by tricking Nack into thinking that she would join his group, and then kneeing Nack in the groin. He tried to get revenge by killing the princess, but was thwarted when Mina Mongoose took the bullet for Sally.

Nack managed to get away and was offered a job in Station Square by an unnamed client who wanted to know about the Master Emerald of Angel Island. Rouge the Bat overheard their conversation and flew to the island herself, but it is unknown if Nack actually took the job or not. Nack later made an attempt at assassinating Mina, having been hired by Robotnik because the doctor couldn't stand her music. This was probably also an attack aimed at the morale of the Kingdom of Acorn, as Mina's songs were often written to support the troops. He later gave in to one of Sally Acorn's threats and got thrown in jail. When the Destructix got thrown in jail after an embarrassing defeat at the hands of the Freedom Fighters and Chaotix, Nack started taunting them. Shortly after that, Mammoth Mogul freed the Destructix from jail, and Nack escaped during the chaos, hinting that he was going to poison his former gang of weasels before he left, as he "didn't need the competition".

He later appeared conducting reconnaissance to verify claims of an auction of the Master Emerald being held by Rouge the Bat, only to be caught in a sting operation by the Freedom Fighters, resulting in him being imprisoned yet again. The only consolation he might have had was that several other villains, Mammoth Mogul, Ixis Naugus, Bark the Polar Bear, and Bean the Dynamite, were also tricked and captured. Mogul was even knocked out by Sally Acorn piloting Nack's own Marvelous Queen air bike, which was afterwards given into the ownership of Rouge, who used it to carry the five would-be thieves to jail. Nack was then further incarcerated when all but a small handful of the inhabitants of Knothole were captured during an assault by Eggman's Egg Fleet, though was soon freed when said survivors mounted a rescue operation to liberate the prisoners. Throwing in his lot with Mogul and the others, he was apparently eager to assist the Mammoth in taking over New Mobotropolis after they were transported to it. Unfortunately, Nack didn't even get the chance to fight, as he and the other four criminals were teleported to a new prison, courtesy of Sally's computer friend NICOLE. Naturally, being imprisoned again after being defeated so easily has extremely hurt the Weasel's vague sense of dignity. He did, however, join the other prisoners in first taunting Elias when he came to visit Amadeus Prower in the prison, and then egging on Sonic and Tails during their scuffle inside the prison.

Nack is a violent and dangerous criminal, one of the few Mobians found regularly in the Kingdom of Acorn who will use guns. He will do anything for a profit, and will work willingly for high-paying employers or his own agendas. Nack is disliked by virtually everyone, from his rival and sister Nic to his former partners in the Destructix to his enemies the Freedom Fighters. Of all the indignities he has suffered, nothing upsets him more than the fact that he has been arrested time and time again (particularly now).
