Happy Birthday, Millie Bobby Brown! Eleven's Best Moments on 'Stranger Things'

And just like that, “Stranger Things” made it even easier to be Eleven for Halloween. Her season 1 disguise, intended to help El blend in at school, is an homage to the one that Gertie makes up the alien in in “E.T.”

Pretty much every Eggo crunch in the show is perfect. Eleven’s affinity for the freezer-aisle treats isn’t just because they’re delicious. They were her main choice of sustenance ever since Mike snuck them down to her when she was hiding out in his basement.

Every moment between Hopper and Eleven is tender, even when it’s funny or when they butt heads. But by the end of season 3, when we were still uncertain about Hopper’s fate, nothing hit quite like the emotional letter that Hopper leaves El, reminding her that when life hurts you, “remember the hurt. The hurt is good.”

Eleven goes through a rebellious phase in season 2, attempting to explore her identity through radical changes like slicking back the hair, black eyeliner and looking vaguely punk.

This moment is one of the most blatant, and brilliant, displays of Eleven’s telekinetic powers. After Eleven and the gang reconciled with an embrace, Eleven helped the crew narrowly escape by flipping an agents’ van out of their way.
