*Diane Aardvark is a character that appears in the Sonic Boom series. She is an anthropomorphic aardvark who runs her own ad agency and works a part-time job as a photographer for "Modern Lair Magazine".She is often accompanied by her assistant, Gunther.

Diane is an anthropomorphic aardvark of average height with gray fur and a thin tail. She has a pair of sharp ears and tuffs on the back of her head, a raised white gray muzzle with a black snout and a tuff of smooth gray hair on her head. She also has noticeable wrinkles on her forehead and very dark purple irises. Her attire consists of a short sleeved lavender shirt and purple skirt, a white coat, black high-heeled boots with gray soles, and a golden bracelet on her wrist. She also appears to wear pink lipstick.

Diane is a dignified and aesthete woman. She has a strong passion for her work as a photographer, encouraging her clients in a positive manner to express themselves to their full extend. She also takes great interest in art and poetry, having more than once displayed a poetic interpretation and appreciation for people who express themselves in unique and unorthodox ways. However, she tends to look way too much into what interests her, as she often sees messages in random things and acts which have no deeper meaning to them.

When a creative talent catches her interest (intentionally or not), Diane will boldly support and defend them and their work, even if goes is against others' wishes, like when she ordered Knuckles not to clean up an artistic mess he made, or when she had Gunther back off when he doubted her choice in creative executives. She also displays a slightly sassy attitude when trying to make a point.*
