Princess Kupacious, also written as Princess Kupacius,[1][2] is a character that appears in the Sonic the Comic series published by Fleetway Editions. She was the former ruler of Shanazar until she was overthrown by Dr. Ivo Robotnik. She currently lives on Mobius as a frog, ruling over a pond.


Kupacious had been the ruler of Shanazar for many years. In this time, she had a reputation of being a ruthless princess and very few people tried to cross her.[3][4] Even so, her kingdom was in slight disrepair, with the state of her capital being primitive compared to Mobius' settlements. Things would change with the appearance of Dr. Ovi Kintobor, who used his scientific skills to improve the kingdom's plumbing system. Impressed, Kupacious made Kintobor her Grand Vizier.[1]

The first mission Kupacious gave Kintobor was for him and his "pet" Sonic the Hedgehog to take the chosen children to the Mystic Mountain in order to collect their genies.[1] After Sonic had committed well-intended, but unforgivable crimes against the kingdom, Kupacious met Kintobor in the form of Dr. Ivo Robotnik, who was perfectly happy to divulge Sonic's criminal activity. For this, Kupacious posted wanted flyers across the city demanding the capture of Sonic.[3] While she waited, she would sent her Imperial Guards to catch other felons, such as Kassim, a thief who wished to steal Kupacious' gems (which she herself had stolen).[5]

The princess eventually lost her patience, demanding Sonic's capture by the end of the week or her servants would be placed in the dungeons. Fortunately, Sonic took this moment to infiltrate the palace in search of the Transportation Belt and was captured.[3] Kupacious was not so happy, however, when Grimer allowed him to escape using his own keys. Her temper was quelled somewhat by Robotnik hiring the Death-Trap to arrest him.[4]

Several weeks later, Kupacious grew closer to Robotnik, eventually accepting a necklace from him and left to parade her new gift. She soon heard of Robotnik's plan to merge Shanazar with Mobius and angrily demanded to rule the new world herself. When Robotnik called her an "ex-princess", Kupacious demanded that her guards beheaded him. Unfortunately, this command set off the magic gems in her necklace, turning her into a frog.[6] Boiling with anger at being removed from power, she waited until Robotnik had forgotten about her before stealing his Magic Gem. Once the Dimension Blender had done its work, Kupacious found herself stranded at an idyllic pond on still-intact Mobius. Armed with her Magic Gem and a new crown, Kupacious started life as the ruler over other frogs.[2]


Extremely ugly and nasty, Kupacious reigned over her city with complete selfishness. Her unwillingness to hand out rewards and the treatment of her staff gave her few admirers. Despite this, she still had loyal subjects who pursued her interests to the very end.
