After becoming a hero in the Second World War, Mike was injected with the
eternity serum, which stopped him from ageing, hence Mike still has the same
youthful looks that he had in WW2. Mike later became the director of the
Strategic Weapon of Rapid Destruction. It was in this time as director of
S.W.O.R.D. that Mike was presumned to have been killed. It has recently
transpired that this was not the case, Mike had in fact been lured away by
the previous director of S.W.O.R.D. and the two of them had become trapped
in a virtual simulation of WW2. When Mike had been shot it was in fact an
L.M.D. designed by Stark Enterprises. Mike recently escaped his confinement
and is currently trying to regain his former post as director of S.W.O.R.D.
we can only guess as to why he's chosen to take control (cha right and monkeys
might, well you know) of the Society.
