Skrull Empress is an NPC in Marvel: Ultimate Alliance.
Marvel: Ultimate Alliance Story
When the Ultimate Alliance arrives on the Skrull homeworld to get the Mounic Inducer from Galactus, they run into the Skrull Empress, as well as Paibok and Super Skrull. However, the Skrull Empress stops the two from attacking them and makes a deal with the Alliance where if they can open the main hangar door she'll give them info on Galactus' weakness and lets them take either Super Skrull or Paibok with them to the control room.
But, once they open the hangar door, she reveals she lied since they should know that Galactus has no weakness and orders Super Skrull and Paibok to defeat them.
