S1E1 The Head Saves The Earth

One morning, Jim is shocked to discover that his head has inexplicably grown to an enormous size. Mortified, he spends almost an entire week hiding in his apartment before finally venturing out to consult a head specialist. Unfortunately, Dr. Axel has no answers to offer, leaving Jim frustrated as he heads home. On his way, he is ambushed by a group of thugs, unaware of the surprise in store for them. Jim's head splits open, revealing a small purple alien named Roy, who swiftly defeats the attackers before retreating back inside. Confused, Jim learns that Roy is on a mission to thwart a parasitic alien named Gork. Meanwhile, disgruntled FBI agent Dr. Lucas Elliott becomes intrigued after hearing the thugs' wild story on the news and decides to track down Jim.
