Archimedes

Archimedes is a dark red fire ant who lives in an Floating Isle.

It was after the first meeting with the Chaotix that Knuckles that met Archimedes. In a "test" of sorts, Archy "kidnapped" the Chaotix and held them "prisoner" in The lost Grand Conservatory where he awaited Knuckles to find him via various clues scattered across The Floating Island. It took Knuckles awhile but when he found him and the Chaotix they all had no idea of what was to happen next.

After the first defeat of Enerjak, Archy has been like a mentor to Knuckles, but he has kept several secrets. Fire ants live to VERY ripe old ages and Archy is no exception. He trained several previous guardians including Knuckles's own father, Locke. Archimedes knew of Locke as well as the Guardian homebaseat Haven, even though Knux thought them all to be dead. Archy is also a valued member of The Council Of Ants. The Council - which resides in the Lava Reef Zone serve as advisors to the echidna guardians in their time of need.

After Robotnik took over Angel Island, Archimedes was charged by Locke with doing all he could to protect the Master Emerald. This he did. Also, Archimedes hypothesised correctly that Knuckles would regain his chas powers if exposed to the Master Emerald.
