Constable Odo is a uncommon Legendary Creature — Shapeshifter Detective card from Star Trek (TRK), collector number 230.
When Constable Odo enters, choose one — • Tap target creature an opponent controls. Put two stun counters on it. (If a permanent with a stun counter would become untapped, remove one from it instead.) • Investigate twice. (To investigate, create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")
