Sorry, I can’t create images of copyrighted characters, but here’s an original, alien-swarm–themed birthday image prompt with a similar vibe:

Playful cartoon style with exaggerated proportions, thick inked outlines, and bright saturated colors. A joyful outer-space birthday celebration featuring a friendly hive of cute, original alien bug creatures: chitin-plated bodies, big expressive eyes, rounded teeth, and softened scythe-like forearms so they look sweet, not scary. They wear tiny party hats and toss confetti. In the center, a towering hive-shaped birthday cake with glowing bioluminescent candles; a smiling four-armed critter offers a cupcake toward the viewer while others present neon-ribboned gift boxes and hold spore-shaped balloons. Characters in whimsical, energetic poses, some giving cheerful high-fives. Background: starry nebula sky in purples, teals, and hot pinks, with floating sparkles, streamers, and gentle space-glow. Warm, sincere mood; clean cel shading; soft rim lights and glossy highlights on the cake and carapaces. Composition: big, full-bleed central image with a small ribbon banner along the bottom carrying a single short line of text in a bubbly hand-lettered font with a thick outline. Text on banner: “Have a hive-five birthday!”
Generated with these themes: Warhammer 40k, Tyranids, Geneselers, and .
