Just like their friends over at the Today show, the hosts of Good Morning America take Halloween very, very seriously. Like they have for the last few years, the hosts and guests put their own fun spins on some of the year's biggest pop culture moments. Michael Strahan stepped into a giant Pikachu suit as a nod to everyone's renewed obsession with Pokémon, while Jesse Palmer channeled his inner superhero with a Captain America costume. T.J. Holmes got all gussied up as Tyler Perry's Madea character (complete with her signature red dress and gray wig), and Amy Robach busted out her best Sia with a giant black-and-white wig and Maddie Ziegler stand-in.
Alfonso Ribeiro and Sara Haines's Ghostbusters costumes were some of our favorites, as were Dancing With the Stars pros Maksim Chmerkovskiy and Peta Murgatroyd's interpretation of Suicide Squad members Harley Quinn and the Joker. Meteorologist Ginger Zee looked cute as a button as Pixar's Dory (hopefully she was able to remember the forecast), but Lara Spencer had the best costume out of the bunch. She ditched her blond hair for Alexander Hamilton's dark ponytail and facial hair for a look that will surely make Hamilton's Lin-Manuel Miranda proud.
