I’ve said it for years now – the most powerful person in the MU is the Invisible Woman. With her ability to create airtight force fields there really is no Earth bound hero who could take her on. One force field later and you have a mighty, muscle-bound super just gasping for air! Well turns out she ain’t the only one who can make that trick work! Songbird, of the Thunderbolts, can make her sonic scream turn into “hard sound”. Whatever that means. It takes the Hulk by surprise – as well as most of the readers!
