Duo 1: The Yin-Yang Globes

• Character A (Yang): A bright, sunny yellow globe with a cheerful, almost mischievous grin. He's energetic, optimistic, and prone to impulsive actions. His body is slightly larger and more rounded than his counterpart. He has small, spiky protrusions around his equator, suggesting a dynamic, active personality. He might have tiny, glowing embers or sparks constantly flitting around him.

• Character B (Yin): A cool, deep blue globe with a calm, contemplative expression. He's thoughtful, strategic, and prefers to plan before acting. He's slightly smaller and smoother than his counterpart, with a more serene, flowing appearance. He might have swirling patterns of darker blue or purple across his surface, representing his introspective nature. He could have a faint, ethereal glow.

• Combined Form: When combined, they form a larger, perfectly spherical globe with a swirling pattern of yellow and blue, representing balance and harmony. The combined form could possess abilities related to energy manipulation or elemental control (fire and water, for example). The combined form's personality would be a balanced blend of both characters, capable of both impulsive action and careful planning.

Duo 2: The Mismatched Maracas

• Character A: A vibrant, red maraca with bright yellow detailing and exaggeratedly large, expressive eyes. He's loud, boisterous, and loves to be the center of attention. His design is slightly more elongated and irregular, reflecting his chaotic energy. He might have small bells or other embellishments that jingle when he moves.

• Character B: A calm, teal maraca with subtle silver detailing and calm, almost sleepy eyes. He's quiet, reserved, and prefers to observe rather than participate. His design is more symmetrical and perfectly round, reflecting his composed nature. He might have a more muted, subtle texture.

• Combined Form: When combined, they form a larger, double-headed maraca with a balanced, yet striking appearance. The combined form could have the ability to generate different rhythms and sounds depending on the combination of their individual personalities. The combined form's personality would be a blend of energetic enthusiasm and quiet contemplation, capable of both lively performance and thoughtful consideration.

Duo 3: The Clockwork Cogs
