Ms. Marvel, Vol. 1

Ms. Marvel has travelled to Avengers Mansion to seek their resources to find a way to go after Tiger Shark, who has just escaped into the ocean with Namorita as his hostage. This leads to a brief battle against the Beast and Scarlet Witch. After everything is explained, the two Avengers allow Ms. Marvel to use their lab to devise a way to allow her to breath underwater, a task at which she is able to succeed.

Tracking down Tiger Shark to a sunken battleship, there she fights against Tiger Shark, who uses the sunken ship's missiles and a squid to try and stop her. However, in spite of these efforts, Ms. Marvel gets up close and battles Tiger Shark hand-to-hand. The battle ends with Ms. Marvel beating Tiger Shark and knocking him out. However, it's at the moment Ms. Marvel's ability to breath underwater wears off, and she also blacks out. When she comes to, Ms. Marvel finds that Namorita had summoned a rescue ship from Atlantis that came to their rescue, and took Tiger Shark into their custody.
