Dendrotoxin Grenade

The Dendrotoxin Grenade is a grenade version of S.H.I.E.L.D.'s Night-Night Gun built by Cybertek, Inc.

"T.R.A.C.K.S."
After Centipede Group's multiple encounters with Agent Phil Coulson's team, they somehow acquired the specs of Night-Night Gun designed by Agents Leo Fitz and Jemma Simmons

Ian Quinn, one of the group's operatives, handed the specs of the gun to Cybertek, Inc, that transformed it into a grenade.

The Dendrotoxin Grenade reveals an airborne modified version of the dentrotoxin used in the bullets, that renders the targets into its area of effect in a state of unconsciousness that seems as if time has not passed since the explosion of the grenade.
