Mikio Menjo is credited on Pokémon Trading Card Game cards in 2003. Their known contributions appear in Aquapolis, part of the E-Card series, and include a small number of illustrated cards. Across these credits, Menjo’s work is associated with Pokémon and Trainer cards rather than Energy.
The available illustrations combine a cartoonish, playful approach with traditional fantasy-leaning illustration. Compositions skew dynamic, supported by vibrant, bright color choices that can shift into cool tones and higher contrast. A mix of lighthearted and energetic moods is also present, alongside moments that read as serene or mystical. One referenced card is Kingdra.
