Odo (alternate reality)

In an alternate timeline future of the alternate reality created by Nero's time travel and Q's removal of the USS Enterprise from the 23rd century, Odo is a shape-shifting Changeling from the Gamma Quadrant. He was found by a Free Federation scientist in 2348. Odo helped Benjamin Sisko, Captain James T. Kirk, Commander Montgomery Scott, and Lt. Nyota Uhura escape by posing as a Jem'Hadar. Odo and the others were then beamed aboard the USS Defiant and then went to Earth.
