The scene unfolds in a whimsical blend of cartoon and fantasy, as if it sprang from the pages of a vibrant graphic novel. At the heart of the card, a colorful, animated street party takes place in a charming cityscape reminiscent of a bustling comic strip.

On the left, Deku from "My Hero Academia" stands energetically with his iconic green hair and costume, holding a giant birthday banner high above his head. The banner is festooned with sparkling letters that read, "Happy Birthday, Brian!" Behind him, Nezuko from "Demon Slayer" peeks out adorably from her wooden box, holding a festive party horn to her mouth, with confetti bursting out in all directions.

To the right, Solo Leveling's Sung Jin-Woo stands in his sleek, shadowy attire, grinning as he uses his summoning powers to conjure up a cake in the shape of Brian's name. The cake is a tower of multi-layered, technicolor frosting, with candles flickering at the top.

In the center, a mafia boss baby, dressed in a sharp pinstripe suit and fedora, holds a microphone, leading the eclectic group in a chorus of "Happy Birthday". His oversized sunglasses glint mischievously under the street lamps, echoing a classic gangster vibe with a humorous twist.

In the background, a post-apocalyptic landscape subtly hints at "The Last of Us", where lush greenery overtakes crumbled buildings, but with colorful balloons tied to the ruins, bringing life and celebration to the scene. A small group of characters from the various themes, including a grinning Joel and Ellie, wave joyfully from a nearby rooftop, holding a banner that says, "You're our hero, Brian!"

Above, the sky is filled with clouds whimsically shaped into the letters spelling "BRIAN", a nod to the ethereal creativity inspired by Winsor McCay. It's a lively and vivid tableau, each character and element uniquely representing their origin while collectively creating a singular, jubilant birthday celebration for Brian.

Generated with these themes: Deku, nezuko, solo leveling, mafia boss baby, my hero academia, demon slayer, last of us, all wishing brian happy birthday.
