Seekers are enemies in Ratchet & Clank. They are fought in the Blarg Depot, Gaspar during "Find the Pilot's Helmet", and in the Gadgetron site, Kalebo III during "Get past the blarg". They are small, black, levitating, robotic balls with small arms, used by Drek Industries, functioning as a mobile explosive.
Seekers will lie in wait in groups until Ratchet approaches, at which point the group will attack. They are quick and well-aromred, and home in on targets, folding their arms into themselves, then flash red and explode after three seconds. They can be defeated immediately with the Walloper, which is best to kill them when close. Alternatively, the Bomb Glove or Pyrocitor can fight them off, but aiming is difficult when close to Ratchet. If they explode and hit Ratchet, they will not drop bolts, but if Ratchet dodges their explosion or destroys them first, they will.
