Hal is a character from Mega Man: Fully Charged. He used to attend Silicon Central, the same school that Aki Light attends. He also used to be Silicon City's biggest prankster, as he created something called "The Big Fade Away", which is known to be the best prank ever.
Hal is an old, brown and grey robot with an orange bow tie. He also has tiny windshield wipers on his eyes, which he uses to make his eyes more clear, but most of the time they just smudge his eyes more, making it even harder for him to see.
