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]...;)
I haven't had TV for a while either - guess that's good.
Ah, I see. A shapeshifter. That's Kerry all right.
