Marjo (also spelt as Majo or Majyo, Lady Margot in Italy, Ratavari in South America, Lucinda Skullduggery in the Time Fighters dub) is the head of a gang composing of herself, Grocky, and Walsa, and she is the main antagonist of the original Time Bokan series. Her name is play on the Japanese word for witch, “majo”, and it also reflects her personality.

A 30 year old woman living in an luxurious mansion, Marjo is obsessed with obtaining Dynamonds for wealth and power, absolutely nothing else will suffice. She planted Grocky with Dr. Kieta and his crew with the intent of using the Time Mechabuton to find the elusive gems. Marjo is not satisfied with the one Grocky obtains from Parrosuke, the parrot that took off in the time machine during Dr. Kieta’s test run of it, so she and her goons attempt to hijack the Time Mechabuton and Parrosuke away from Tanpei, Junko, and Chorobo to no avail.

Shortly afterwards, Marjo and her minions travel around their own time machine, the Gaikottsu, to find the Dynamonds before the Time Bokan crew and possibly eliminate them as well. When traveling around in the Gaikottsu she tends to lounge around in the sofa-like backseat, though she’s usually standing in-between Grocky and Walsa during a battle with one of the Time Bokan mechas.

Although she is quite attractive, her beauty masks a cruel, spoiled, self-absorbed witch. (I know, I know.) Marjo cares for nobody but herself, and relies on theft, deceit, and if given the chance, even murder on her quest for the Dynamonds. She’s also extremely impatient and will get hasty in tense situations, more often than not condemning her gang to failure.

Although she’ll congratulate Grocky and Walsa on a job well done, she thinks lowly of her henchmen and becomes very aggressive towards them when they screw up or things aren’t going her way, even when they try to be supportive of her. She also greatly despises the group that pilot the Time Bokan mechas, especially Tanpei since he tends to directly interfere with her plans.

Marjo can be very manipulative, and she uses her charms to either deceive people and turn them against the Time Bokan crew or gain the favor of a villain or a higher up in a era. These tactics tend to be short lived, as her “allies” either don’t have Dynamonds or were shown the truth by the Time Bokan crew.

In the final episode, Marjo is overjoyed when she finally finds the Dynamonds (all this time in a park in the present) and attempts to take off with as many as possible, much to the protest of Tanpei and crew. But when the Dynamonds begin to turn to stone, she suffers a breakdown and begins to throw an epic tantrum. Absolutely furious, Marjo challenges Tanpei to one final showdown between the Time Dotabattan and the Gaikottsu.

Although the battle is in favor of Marjo’s gang, they lose anyways purely out of dumb luck. Driven insane by these turn of events, she’s last seen prancing around in a childlike state of glee over the “Dynamonds” in the night sky. (Though if one takes Royal Revival, Bokan GoGoGo!, or Kaitou Kiramekiman as followups, she becomes relatively sane again.)
