A natural plant that grows in the old cave systems beneath Arkham Island, the mould that was produced within these saplings were capable of reversing all effects that the Titan strain had on a human host, as well as curing them from any negative impact the chemical would have on them.
"Batman: Arkham Asylum"
After confronting Poison Ivy about a cure for the Titan formula, Ivy
admitted to Batman (under the influence of blackmail) that there was
a plant that had been growing deep beneath Arkham Island that's
spores could be used to reverse the effects of the formula. Upon
further pushing he discovered that it was thriving in a network of
abandoned sewer tunnels that had come to become Killer Croc's lair.
Reaching the mouth of the lair, Batman set up a scanner and sonar
beacon on a nearby water pipe, tuning it to detect trace elements of
the spores and lead him directly to them. Tracking them down through
the labyrinth (at various distances from the entrance), Batman
harvested five individual samples, each time gathering more and
more of the anti-venom mould needed for full synthesises of an antidote.
Completing the task, Batman escaped from the Lair and returned to the
Batcave, setting up the Batcomputer to create an compound to counter
the effect of the Titan strain. However the process was more
complicated than he had anticipated it to be, commenting to Oracle
that the mould he had collected did not produce much. He goes on to
tell her that the spores will definitely stop Poison Ivy, commanding
the Batcomputer to run further tests to determine whether it was
possible to reverse the effects of the Titan. Setting up a programme
to create more of the antidote, Batman had just finished the first
batch when Ivy's vines destroy the temporary Batcave. Her destruction
of the cave ensured only one sample of the anti-venom could be
manufactured, with Batman 94% certain that the compound will actually
work.
