Happy Mother's Day, Marvel fans! We have seen many Marvel stars sharing some love for their moms on social media today, but what about those fictional mothers we know and love? In addition to celebrating the real moms out there, many people have taken to social media to honor their favorite onscreen moms. The Cosby Show's Clair Huxtable (Phylicia Rashad) has been a hot topic on Twitter today, and she's not the only TV mom to get some love. Many Marvel fans are taking to the social media site to show their appreciation for Wanda Maximoff (Elizabeth Olsen).
