I Bet I'm Stronger Than You

This is based on an idea I had, where Captain Marvel (Billy Batson) met characters from the Marvel Universe. In this case, he meets Molly Hayes (aka Princes Powerfull, aka That girl with a-million awsome hats). She seems to think she's stronger than him. But since they're not idiots the'll probably just arm-wrestle or throw boulders at mountains. You know, instead of fighting eachother like every superhero encounter ever.
