It Came From Next Door

It Came From Next Door is the first half of episode 1 of season 1 of Alex Adventure''. ''It first aired on Nickelodeon in the United States on August 1, 2003.

Summary
Alex (also known as HA-9, a crime-fighting teenage robot boy created by Dr. Blackman to be Earth's protector) makes him first contact with the outside world, meeting Brad and Cheese Carbunkle for the first time. While Brad immediately accepts Alex as a new friend, Cheese does not quite see him as anything other than a "evil robot cyborg".

Plot
Cheese, while practicing baseball, hits a ball that flies through a window in neighbor Dr. Susan Blackman's front door. His brother Brad instructs him to get the baseball back, but when Cheese knocks at the door, nobody arrives. He wanders inside, seeing various pieces of machinery and robot parts strewn about. When he reaches the baseball, it is handed to him by a shadowy, imposing figure, later revealed to be HA-9. Cheese flees in terror without taking the ball, where he is intercepted by Brad and informs Cheese that he encountered a "hideous bloodthirsty robot". Ms. Blackman overhears this conversation, and Brad tries to explain the situation, but Blackman slams the door in his face, so he leaves, only to notice the robot while arguing with his brother.

Dr. Blackman walks back into her house berates HA-9, who prefers to be called "Alex", for having left his room and instructs him that she must not encounter any of the human population, especially teenagers. She instructs Alex that there is a meteor warning, but Alex disregards it because most meteors typically burn up in the atmosphere. When Dr. Wakeman leaves the room, Brad climbs in through Alex's window and meets him. The two leave and hang out, playing hackey sack and chasing ice cream trucks, among other things, while Cheese reluctantly tags along, still suspicious and nervous about Alex. However, while they were playing, the hackey sack which Alex booted through the atmosphere became part of the meteor, rendering it a “planet destroyer” class.

Alex rockets off to destroy the meteor as soon as he gets the warning, and dispatches it quickly. As he returns to Earth, he and Brad realize in shock that Alex had accidentally taken Cheese along with him, as he had been inadvertently attached to his wings. While Cheese is a bit charred from re-entry, he is impressed by Alex's abilities and declares him to be "so cool!", now no longer afraid of him.

Dr. Blackman oversees this, and decides that giving HA-9 some time off couldn't hurt. However, the camera pans out to outer space, where several (presumably hostile) spaceships are closing in on Earth...
