Uma Arachnis

Uma was originally a ninja of the Gossamer Clan in the Dragon Kingdom. A gifted reader of the Web of Fate, she learned that the Source of All would fall into the clutches of evil. Upon learning of this, she set out to personally destroy the Source of All and its related relics.

Sent to the Zone of Silence at an unknown time and for unknown reasons, Uma Arachnis was among the many exiles to the Zone who swore allegiance to Ixis Naugus in exchange for his magical protection, the others including Maximillian Acorn, Warlord Kodos, and Feist. Granted the ability to shift between organic and crystalline form, Uma could become an even more formidable opponent and was able to retain her sanity while in the Zone. She was present when Dr. Robotnik came to the Zone and was brought before Naugus and his other minions by Feist.

Eventually, she escaped alongside Naugus and Kodos after the Knothole Freedom Fighters dispatched a probe into the Zone, and at Naugus' behest battled the likes of Sonic the Hedgehog and Geoffrey St. John. During the fight, Uma attempted to pull King Max off his sick bed and shatter him, as his body was mostly crystal, but was stopped by St. John. When Naugus realized his enemies proved too much for her and Kodos, Naugus transformed them both into their crystal forms, making both virtually indestructible. Sonic quickly brought an end to her attack, however, by shattering Naugus' crystal sceptre, ending the magic that allowed her to move while crystallized. She and Kodos were then moved in their immobile forms to Devil's Gulag, abandoned by their supposed benefactor.

When a blast from one of Robo-Robotnik's satellites allowed the prisoners of Devil's Gulag - Snively Kintobor, Sleuth Dog, Drago Wolf, Nack the Weasel, and the Fearsome Foursome - to escape, they brought Kodos and Uma along with them. By unknown means the two were reanimated and restored to their original forms. Swearing loyalty to Snively, the leader of the group, they joined the others in kidnapping Nate Morgan, whose technical genius Snively hoped to use in his takeover attempt. They fought with the Knothole Freedom Fighters at Deer John's in Mobotropolis, and were able to defeat them and take Nate hostage. Uma would then fight the Royal Secret Service briefly after they came to Nate's rescue, but managed to escape with Kodos on Sonic's stolen biplane, Winged Victory.

Some time later, Uma and Kodos found themselves fighting against one another, both becoming deranged and terminally ill due to the toxic effects of prolonged exposure to radiation poisoning in Robotropolis. While Uma took the Sword of Acorns from Robotropolis and gave it to Kodos, Uma later stole it back from him while he slept, as he suggested with the sword he would no longer need her.

Uma managed to hide the sword, but Kodos continued to chase and attack her. She managed to catch Sonic in her web and use him as bait to lure in Kodos, which she successfully did, knocking him unconscious. After this, she cut Sonic from the webbing and allowed him to take Kodos back to Knothole while she vanished. Unknown to Sonic, Uma had just laid her eggs in a nearby tree. After this she took this time to hide the Sword, realizing that she could not allow it to fall into the wrong hands.

A few days later, Uma was once again attacked by Kodos, who escaped after being briefly treated in Knothole's hospital for his own radiation poisoning. Uma, succumbing to the toxic effects of radiation poisoning from when she was hiding in Robotropolis, was no match for Kodos. Before she died however, Uma managed to tell Princess Sally where she had hidden the Sword of Acorns. Uma died shortly afterwards from the radiation poisoning and wounds obtained from Kodos.

Uma's memories were passed down into her six children, the Arachne, making them continue in her quest to destroy the Sword of Acorns and other Source of All relics.
