Dark Doctor Mavro (闇博士マーブロ Yami Hakase Māburo) is the main antagonist of Shuriken Sentai Ninninger vs. ToQger The Movie: Ninjas in Wonderland.
Mavro was a former member of the Evil Army Shadow Line, and the owner of Dark Ninjaland. His master plan was to make a personal dark clone-hybrid ninja, use it to drain people's hopes and dreams, and consume the world in darkness. To this end, he resurrected General Schwarz as Ishikawa Schwarz Goemon, Madame Noir as Mochizuki Noir Chiyome, and Baron Nero as Kirigakure Nero Saizou. He also turned Takaharu Igasaki into Dark AkaNinger, but ultimately failed and was taken out by Takaharu and Right's ToQ Fury Slash only to survive and summon three Kuliners which soon combined into Cho Cho Kuliner Robo. He overwhelmed Shurikenjin, BisonKing, and even Ha-Oh Shurikenjin but was ultimately killed when he and his robot were destroyed by Ha-Oh ToQ Dai-Oh's OtomoNin Connection Splendid Crash.
He was a mad scientist whose only interest was making the ultimate dark ninja clone warrior.

- Weight: 201 kg
Dark Doctor Mavro is a brilliant but evil scientist capable of completely corrupting Takaharu Igasaki into his evil minion and wields a massive staff with a crystal orb on the end. Aside from his brilliance, Mavro's ultimate attack seems to be a massive purple energy slash that he could fire from his staff that took down all six Ninningers with one hit.
- Dark Doctor Mavro is played by Ryota Yamasato (山里 亮太 Yamasato Ryōta).
Behind the scenes
- His name is the Greek word for "Black" (μαύρο).
- He shares the same name as Emperor Mavro from Power Rangers Super Megaforce.
- The left arm from Dark Doctor Mavro's costume was combined with the body of Bergian Kuronen and the head of Hound Shadow to create an unidentified Gangler Monster seen in Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger Number 1: The Troublemaking Phantom Thieves.
- Parts of his costume were used to inspire Scrozzle's design from Power Rangers Beast Morphers.
