Christina I

"Ah. So that Princess Christina, eh? Well... I bet this little girl must've trying to preventing the Coalition of the Red Star from taking over all of Adventure Bay. Such failure would lead to our inevitable doom."

--Su Ji-Hoon, Adventure Bay's Last Stand

Christina I is a young preteen girl who is set to eventually become queen of Barkingburg. She is a protagonist of the Mission PAW sub-series of PAW Patrol. She is the owner of Sweetie, a sneaky pup with a desire to steal the crown in an effort to become the queen. The Princess is often seen with the Earl of Barkingburg.

Personality
The Princess of Barkingburg is a kind and elegant girl. She loves her pet puppy Sweetie but often fails to notice Sweetie's evil intentions. She believed Sweetie's lie about the crown being stolen by Chase (even though Sweetie was the one who took it). She rewarded Sweetie by letting her wear the crown (until the princess eventually becomes the queen), until Ryder proved Sweetie wrong with video footage. Despite this, and locking Sweetie up in a fenced area as punishment, she still loves her puppy.

In When the Cold Breeze Blows Away, like all supreme leaders, she is extremely mad, nervous, stressed, frustrated and paranoid about World War III and what's wrong to her kingdom, Barkingburg, and its capital city, Adventure Bay, especially the Grand Alliance, most notably in the Battle of Adventure Bay.
