—Dead Lycan’s body tag |
” |
Thasarine is a drug or serum developed by Vampire Death Dealer researchers to arrest a Lycan’s regression from its werewolf form, as they normally revert to human form after death.
The drug is seen as having been used in Underworld: Evolution, where Selene and Michael Corvin, having come to a Vampire Safe House to re-arm (and for Selene to leave Michael there to keep him safe), discover a dead Lycan test subject, still in its Werewolf form, despite having been long dead. Its body tag identified that the subject had been injected with 850ml to “arrest regression” for further study of its anatomy in its werewolf body.
Its counterpart is the Anti-Change Enzyme developed by the Lycan scientist, Singe, an enzyme designed to stop and delay the transformation in persons who, while they have been bitten, have yet to transform into Lycans themselves.
