In the end, everybody won in the Super Bowl rivalry between Captain America star Chris Evans and Guardians of the Galaxy star Chris Pratt. Everybody except the Seattle Seahawks, that is.

Following some friendly trash-talking online, Boston native Evans and Seattle resident Pratt settled on a wager: If New England won Super Bowl XLIX, Pratt would wear a Patriots jersey and make an appearance at Christopher's Haven, a home away from home in Boston for young cancer patients and their families while they undergo treatment at nearby hospitals (it's a favorite charity of Evans).

However, if the Seahawks won, Evands would dress as Captain America and visit Seattle Children’s Hospital while carrying a 12th Man flag.

Evans and Pratt were in Phoenix, Arizona, on Sunday to see the Patriots beat the Seahawks 28-24, but the Star-Lord actor was gracious in defeat:

Thank you @Seahawks for a wonderful year and congrats on you NFC championship. So close. The #12s love you!!!

However, it's not only Seattle Children's Hospital that will be receiving a visit from the two Marvel movie stars:

Thank you to @prattprattpratt for being a good sport. I'll be there with you at @chris_haven, and don't worry @seattlechildren, we'll be

coming there too! And lastly, I don't think anyone can ever doubt the mental toughness of Tom Brady. Tough couple weeks, but he showed why

Their wager also inspired a charity T-shirt from TeeFury, with proceeds going to Christopher's Haven and Seattle Children's Hospital (the tees can be purchased through Feb. 10).
