Masha

マシャ

Masha (マシャ) is a robot created by Ryou Shirogane to detect Chimera Anima and Mew Aqua. Originally identified by the model number R2000, Ichigo nicknames the unit "Masha" after her crush, Masaya. Masha likes the new name and enjoys being with Ichigo.

Spoiler

When the Mew Mews defeat a Chimera Anima, Masha consumes the jellyfish-like parasites that emerge from infected animals, plants, and humans. Masha can also merge with Mew Aqua found by the Mew Mews to transform into the Mew Aqua Rod, allowing the Mew Mews to perform the Ribbon Aqua Drops healing attack. Masha lacks the capability for high-level speech, primarily saying "pi" and "tweet." Masha is occasionally shown saying regular words, with the most advanced example seen in Tokyo Mew Mew a la Mode, where it says "Masha is going with Ichigo!"
Masha is the only character in the series to also appear in Mia Ikumi's short story Tokyo Black Cat Girl, which would eventually become Tokyo Mew Mew. Though Masha has the same name and general appearance in both series, in Tokyo Black Cat Girl Masha is a very different character. Instead of being a robot, Masha is an intergalactic police officer who partners with Princess Azumi to defeat alien parasites called the Baku. Masha has the ability to change disguise as a cell phone mascot, can speak in complete sentences, and is capable of fighting the Baku in small numbers.
In the Tokyo Mew Mew anime adaptation, Masha is capable of speaking in short sentences and is shown trying to help the Mew Mews when they fight. In the original Japanese series, Masha is voiced by Junko Noda. In the Mew Mew Power English adaptation, Masha's name is changed to Mini-Mew and is voiced by Tom Wayland.
