The Battle at Mar-Vell's Laboratory was the altercation between the last surviving group of Skrull hiding in Planet C-53s orbit, and a Kree offensive including the Starforce.

The battle was initially a chase for the Tesseract, where the stakes later escalated when Accuser Warships arrived to nuke C-53's surface with Kree Ballistic Missiles.

Captain Marvel stopped the bombings and neutralized all members of the Starforce, and finally Yon-Rogg in the Mojave Desert, while the Skrulls escaped down to Louisiana for temporary refuge.
