PLOT:

In the year 20XX, Planet Earth is attacked by three Stardroids with ears bigger than those of an elf: Quiche, Pie and Tart (yes, those are their names). They use small jellyfish-like robots that infiltrate the systems of Earth's robots to take them over and turn them evil. These three Stardroids obey a mysterious Stardroid leader named Deep Blue.

At around the same time, a new mysterious sword-wielding hero calling himself the Blue Knight entered the scene. He even helped Mega Man a couple times, but his true motives are unknown. He has a suspiciously similar design to the three Stardroids (with the same huge ears, no less) and is made of the same alien materials. Mega Man and Dr. Light both suspect this Blue Knight might secretly be Deep Blue...

However, there is a problem: The Blue Knight happens to be the boyfriend of Mew Ichigo, one of Dr. Shirogane's team of environmental robots known as the Tokyo Mew Mew. Going after the Blue Knight will mean getting through the Tokyo Mew Mew trying to defend him as well, on top of dealing with the three Stardroids too.

ROBOT MASTERS:

DSN001 Mew Ichigo/Wildcat Woman: An ecology robot designed to resemble an Iriomote Wild Cat, built to help preserve mountain biomes. The clumsy but determined female anime protagonist, not unlike Sailor Moon. Fell in love with the Blue Knight at first sight and would do anything for him. Her Special Weapon is Strawberry Surprise, which has nothing to do with strawberries and instead unleashes a continuous blast of intense holy light.

DSN002 Mew Mint/Lorikeet Woman: An ecology robot designed to resemble a Blue Lorikeet, built to help preserve bird habitats. An extremely haughty robot girl with a sky-high opinion of herself, believing herself to be the finest masterpiece of engineering. Dances ballet in her free time. Her special weapon is the Mint Arrow, which is not mint-flavored, it instead fires a projectile made out of air.

DSN003 Mew Lettuce/Porpoise Woman: An ecology robot designed to resemble a Finless Porpoise, built to help preserve the oceans. The nicest, sweetest, most polite robot girl you'll ever meet, she doesn't like fighting but will do it for her friends' sake. Enjoys reading books. Her special weapon is the Lettuce Rush, which is neither lettuce nor a dog, it instead fires blasts of highly-pressurized salt water.

DSN004 Mew Pudding/Tamarin Woman: An ecology robot designed to resemble a Golden Tamarin Monkey, built to help preserve the jungles. A robotic little girl, no older than Roll, who is perky, playful and full of energy. Capable of amazing gymnastics and pretty hilarious to watch go when she's not fighting you. Her special weapon is the Pudding Inferno, which despite the name is not fire-based, it instead sends a tambourine rolling at high speed along the ground (though in the anime it does somehow trap its targets in giant yellow puddings).

DSN005 Mew Zakuro/Graywolf Woman: An ecology robot designed to resemble a Gray Wolf, built to help preserve the forests. A taller, curvier, more adult-looking robot woman, who appears significantly more calm and composed than her fellow robot girls. This is a facade, she actually hides a burning inner rage. Also does fashion modeling. Her special weapon is the Zakuro Spear. A Zakuro is a passionfruit, but this weapon is neither passionfruit nor a spear, instead being a whip of purple light that for whatever reason sets things on fire.

Stardroid001 Quiche: The first Stardroid to arrive at Earth and cause trouble. Playfully cruel, loves to taunt and toy with his victims. Has been thwarted time and time again by Mew Ichigo, to the point he's developed a romantic yandere crush on her. Hates the Blue Knight with a passion, and is also secretly distrustful of his own leader Deep Blue. His special weapon are the Dragon Swords (though apparently they were tonfas in the manga?), which look like sai more than swords.

Stardroid002 Pie: One of the other two Stardroids that Deep Blue sent as reinforcement when Quiche failed his first dozen attempts. Acts as the cold and composed big brother of the trio, with a strategic mind that analyzes the situation and comes up with a plan before acting. Out of the three Stardroids, he's the most loyal to Deep Blue and the only one that never questions his master. His special weapon is Sky Thunder, which he fires off of the fan he holds in his right hand. Actually his fan can shoot lightning, ice and wind (but there is no Robot Master that does all three, so I had to make do with Sheep Man on an ice floor)

Stardroid003 Tart: One of the other two Stardroids that Deep Blue sent as reinforcement when Quiche failed his first dozen attempts. He's the youngest of the three, no older than Mega Man himself, and he very much acts the part. He has a special connection with plant life thanks to his special weapon, Plant Controller.

OTHER BOSSES (SPOILERS FOR THE ENDING OF TOKYO MEW MEW!):

Blue Knight: A mysterious sword-wielding robot that came out of seemingly nowhere at about the same time as the three Stardroids invaded. While his deeds so far have been heroic, his motives seem suspicious. For some reason he also swore to protect Mew Ichigo, and is a complete gentleman to her.

Deep Blue: The Stardroid leader behind the invasion. While he told his subordinates that they were going to reclaim the planet that was once theirs, in reality he just wants to take over the world for his own greedy self. The Blue Knight is a split personality he created so that he could infiltrate Earth society and learn their weaknesses. However it was a split personality, not a disguise, meaning the Blue Knight was able to fall in love with Mew Ichigo and turn against his creator for her sake.
