Facehugger is a minor character in Sonic For Hire. A Facehugger is an alien species that are seen and only appear in the "Aliens" episode.
A Facehugger comes to leap at Tails from the shadows. Sonic notices this and shoots the creature dead. Tails is left in utter shock from this experience, mentioning that the Facehugger managed to deposit an embryo down his throat. Sonic is more annoyed than concerned, stating that Tails technically got to eat something. As Tails tries to speak, a second Facehugger leaps onto his head.
Sonic rolls his eyes and shoots the new one. Thankfully, this one did not get to deposit an embryo, but Tails frighteningly questions why this keeps happening to him. Sonic chides Tails for fooling around, mentioning that they are supposed to find the Xenomorph Queen.
As Tails tries to defend his innocence in this affair, a THIRD Facehugger latches onto him. This time, Sonic leaves it on Tails' face and moves onward, the blinded fox repeatedly bumping into things to catch up with him.
