Hawking

Hawking was the Guardian of the Floating Island when the Dingoes, life-long enemies of the echidnas in general, launched a nuclear attack on Echidnaopolis. Hawking used a dome shield to protect the city from the initial onslaught of the missiles, but the nuclear fallout threatened all life on the Floating Island. Using plans from Dimitri, he created the Hyper Zone Projector and placed Echidnaopolis (along with all other inhabitants of the Floating Island--including the dingoes) into pocket zones. While everyone was safe in their zones, the Brotherhood went about cleaning up the Floating Island and Hawking handed down the mantle of Guardianship to his son, Tobor. Eventually, Hawking returned all Floating Island inhabitants back to the Floating Island, except for Echidnaopolis and the Dingoes. Both returned thanks to the effects of Robotnik's Ultimate Annihilator, which erased all life on Mobius for an instant and broke down barriers between zones. However, when Hawking did his part to save Echidnaopolis, he ended up in a coma, which he never did wake up from and eventually died.
