This is a list of characters with articles or unnamed characters entries who were antagonists during Day 2.
The antagonists of Day 2 were all part of (or at least, affected by) the Los Angeles nuclear attack conspiracy. At the lower levels, this was Joseph Wald's domestic anti-government militia and the Afghan terror cell Second Wave. At the mid-level, this was a cabal of traitors in the U.S. government (primarily the NSA, led by Roger Stanton and his muscle, the Coral Snake commandos) who facilitated the nuclear weapon's entry into the country but wanted to prevent its detonation at the last minute. At the topmost level were oil magnates Peter Kingsley and Max, wanted the bomb to wipe out Los Angeles to profit from the ensuing war between the USA and three Middle Eastern countries.
