Ooze (IDW)

In the IDW continuity, the substance known commonly as ooze is a green liquid that originates in the general region of the planet Utrominon. It was partially the overuse of ooze that ultimately destroyed the planet, as its reserves had been exhausted by Emperor Quanin's ruthless expansionist policies.

Most notably, o oze is the core ingredient of  mutagen, presumably being responsible for the rapid growth and expanded intelligence of any animals who come into contact with it.

The effects of ooze can be extremely varied, but typically it seems to have life-giving or healing properties. When ingested, it can cause a person's body to change into its peak condition without effort, as seen with Arnold Jones and Takeshi Tatsuo. This includes the temporary reversal of the aging process.

Additionally, it was key to keeping the Utroms on Burnow Island alive during their time in stasis. The removal of the ooze had fatal effects on them.

It has nearly limitless healing abilities, having been used to regrow Takeshi Tatsuo's lost leg, reverse the effects of John O'Neil's stroke, and allowed the almost immediate healing of Donatello's critically-injured body. This fluid was also used as part of Oroku Saki's attempt to achieve immortality, which involved mortally wounding himself before being suspended in a casket of ooze, which preserved him for centuries.
