Actors Chris Pratt and Chris Evans have placed the sports dignity of their Marvel superhero alter-egos on the line in the most geektastic Super Bowl 2015 wager ever.

Pratt famously played Star-Lord (Peter Quill) in the 2014 summer blockbuster "Guardians of the Galaxy," while Evans portrayed Captain America (Steve Rogers) in multiple films, most recently 2014’s "Captain America: The Winter Soldier."

As it turns out, Pratt, who grew up in Lake Stevens, Washington, is a big Seahawks fan. Boston-native Evans, on the other hand, roots for the Patriots. So naturally, the match-up between Seattle and New England in Super Bowl XLIX has set these two stars up for some unique — and benevolent (they’re superheroes, after all) — stakes. Here’s how they hashed it out:

Well, well, well @prattprattpratt, looks like our teams are going into battle. For the next 2 weeks, you are not my friend, you are my enemy — Chris Evans (@ChrisEvans) January 19, 2015

@ChrisEvans We both know there's only one Captain America and his name is Russell Wilson. #SuperBowlBound #LOB #Repeat — chris pratt (@prattprattpratt) January 19, 2015

@ChrisEvans OK. Seahawks win you fly yourself to Seattle, visit @seattlechildren hospital as Captain America, waving the 12th man flag. — chris pratt (@prattprattpratt) January 21, 2015

@prattprattpratt I accept. And when the Patriots humiliate your seachickens, I expect Star-Lord to arrive at @chris_haven in a Brady jersey — Chris Evans (@ChrisEvans) January 21, 2015

@ChrisEvans Humiliate my Seahawks? Maybe talk to Brady about deflating your expectations. BOOM! (legion of) You're on sucka. 😊 — chris pratt (@prattprattpratt) January 21, 2015

Pratt, who also stars on "Parks and Recreation," is no stranger to dressing up in the name of charity. Check him out at Children’s Hospital Los Angeles in his Star-Lord gear cheering up a patient.

Whether or not it has the same effect in a Patriots jersey, however, remains to be seen.
