Popular and arrogant, yet compassionate, Steve Harrington is an unlikely mentor and leader.
He often acts as a surrogate big brother to a younger boy named Dustin.
He even helped him find his slimy inter-dimensional pet Demogorgon, D'Artagnan.
His reputation as a protector grew and he soon became a sort of "babysitter" for a group of kids in Hawkins with a knack for messing around with strange and dangerous things.
His courage is unmatched so that he was even able to fend off a Demogorgon when it threatened his friends.
One evening he received a call for assistance from his friend Nancy Wheeler.
He drove all the way to the Hawkins National Laboratory to see if she was okay.
He searched the area but only found her notebook.
Before he realised what was happening the ground opened up and a swirl of black mist filled his eyes.
When he awakened he was in a strange place that seemed familiar but unfamiliar at the same time.
