==History==

A long time member of [[Alpha Flight]], [[Box IV|Madison Jeffries]] served faithfully in a number of battles with various foes. When [[Department H]] reformed [[Alpha Flight]] Jeffries was a part of the team (not in the [[Box IV|Box]] armour). When the new Alpha Flight battled the super villain team The [[Zodiac]], Jeffries was captured. He was then brainwashed, and became the 12th member of the [[Zodiac]], Gemini. When [[Weapon X Program|Weapon X]] operatives annihilated the [[Zodiac]] members, it was with the intention of taking [[Box IV|Jeffries]] captive for his transmutation powers.
