Omnidroid
Draw an Omnidroid on a large piece of cardboard (you can find pics on Google, just type "omnidroid" and go to images), cut out a face and have a volunteer put their face in it while the children (superheros) throw water balloons at the 'face' of the Omnidroid. The volunteer at our party was dad, but uncle or godfather will work just as well.
