Doronjo, real name Hiroko Sasagawa, is the beautiful masked leader of the Dorombo gang. A bumbling thief at the age of 24 (or so she claims), she and her equally inept henchmen Boyacky and Tonzura seek out the Dokuro Stone for the mysterious Dokurobei with the promise of a huge amount of wealth.

Doronjo’s “name” is based on the Japanese word “doronko”, meaning “muddy” or “dirty”, something that’s brought up often by various characters. Her reason for starting the Dorombo gang and seeking the Dokuro Stone was to become the richest and most admired woman in the world, although it’s been hinted that what she really wants is to simply settle down and raise a family.

Although she retains previous villain Marjo’s traits of being vain, selfish, and impatient, Doronjo is significantly nicer to her subordinates Boyacky and Tonzura, even though their antics can get on nerves. She’s quick to praise them for achieveing something, and just as quick to scold them (mostly Boyacky) if they blunder. Despite her recklessness, she’s fairly intelligent and quite a smooth talker, which is best seen when she’s pulling a con or trying to get Dokurobei to reveal himself.

Doronjo plans out most of the scams and activities when searching for a Dokuro Stone fragment. During the earlier episodes her face can clearly be seen when in a disguise, although later on she wore a mask When it comes to battling the Yatterman, she has Boyacky and Tonzura do the fighting for her most of the time and at most uses the mecha they were travelling in to pick them up when they lose. Occasionally, the destruction of the Dorombo gang’s mecha will result in her clothes being shredded to revealing levels, although this can happen to all three members.

Her favorite food is french fries and she has a strong dislike of rats, although there is an good reason for the latter. When she was a little girl she came accross a rat that bit down hard on her nose. Because of that trumatic event, she’s absolutely horrified whenever a Yatterman mecha deploys mini-mechas resembling rats or mice.

Towards the end of the series, she begins to have second thoughts about her career as a thief. She develops feelings for Yatterman-1 (Gan-chan) which are obviously unrequited, and at one point imagines the conflict going on to the point where they’re all elderly. When the Dokuro Stone and the truth behind it are revealed and leave the Dorombo gang shocked and with nothing to show for it, Doronjo tearfully disbandons the gang and they go their seperate ways.

Afterwards, Doronjo got married and became the mother of five children, and according to Heisei Time Bokan she also opened up a bar named “Buchikku Dorombo”, decorated with Time Bokan memoribillia. However, she missed the fun she had with the Dorombo gang, and be it the starring role in a OVA, a chance to defeat all the various Time Bokan heroes, or an attempt at a social reform, Doronjo would bring the gang back together for more hijinks during the 90s.

Being the only playable villain in the game, Doronjo is a fighter in both versions Tatsunoko vs. Capcom, with Boyacky and Tonzura assisting her with some of her moves. Notably, this is a rare instance of her directly fighting an opponent rather than relying entirely on her goons. This is prominent after winning a fight where she’s clearly exhausted from having to physically attack someone.
