The King Alien was created by Kenner as part of their Aliens toyline. It appears to lack the ridge on the tail. It looks more like an actual spine, rather than a skeletal ridge. Its head crest is very elaborate, with retracting pieces on the side of the head. In the Kenner action figure, it has two pincers on the sides of its head. They clamp shut to grab objects. the action figure can also squirt water out of its mouth when the tail was squeezed. It is based off the Rogue Alien from Aliens: Rogue
