I haven't had a TV for 25 years and don't get to the movies much. Enlighten me as to who this character is.
Remember the old Star Trek?
Well, about a bazillion spin-off series have eveolved since then and this character ["Odo"] is on one of the spin-offs.
He's a "shapeshifter" in that his body is more or less "liquid" and he can rearrange himself into just about any form he chooses.
[he really does have a lot in common with kerry]...;)
