*Miko Nakadai is a 15-year old girl from Japan with a strong love of American pop culture... as long as it's loud pop culture! Speed metal and wild punk outfits are her thing, and she's always searching for thrills, causing trouble for her mates Jack Darby and Raf Esquivel. She's started to hang out with the Autobot Bulkhead too, helping him get over his fear of hurting his tiny partner and encouraging him to get in trouble with her. However, when the chips are down, she'll look out for her pals and Bulky has her back.

The reckless Miko we know is actually a cover for a vulnerable girl with a slight inferiority complex. She wants to prove herself by leaping into danger head-on, is what it really boils down to. Bulkhead may have been assigned to be her guardian, but Miko has taken to the role for him as much as he has for her. What she lacks in size and power, she makes up for in fierce loyalty and protectiveness for her friends and Bulkhead. She's even got the gall to threaten and take on some of the baddest of the Decepticons. Even Wheeljack has been impressed by the guts this girl has. Now if she could just work on when to actually let loose all that energy...

Miko has brown eyes, fair skin and medium-long black hair with pink highlights and is worn in a low ponytail and two twintails at the top of her head. She is slim, taller than Rafael, but a little shorter than Jack.

She wears a two-toned purple T-shirt under a dark blue tank top with yellow stropes and a little green robot drawing, jean shorts, two-toned purple striped stockings, brown knee-high boots with purple ties and a soft two-toned purple bracelet as a match to her T-shirt.

If there is one word to describe Miko's personality its reckless. She is a thrill seeking adventurer who wants to be in on the action and has no regard for danger or her own safety and certainly no thought as to the potential consequences of her actions. Still she is, at heart, a good person who cares deeply about her friends and the Autobots. She is particularly close to Bulkhead her protector to the point of refusing to leave him at the mercy of Starscream. Her hot-headed and impetuous demeanor cause no end of headaches for her friends and Autobots. She also has a habit and hobby of taking pictures with her cell phone, which actually helped bots from time to time.

Though she may seem harmless, Miko is far more willing than most of her other companions to fight back. When Bulkhead was severely injured by Hardshell she teamed up with Wheeljack in order to take revenge. When Hardshell had Wheeljack beaten and had been ordered to flee in his ship, she instead chose to activate the Jackhammer's weapons systems and blew Hardshell to pieces. When his remains were brought to Megatron's attention, the Decepticon leader was surprised that even a human would be capable of such an act of violence.

Miko's act of killing Hardshell (by using the Jackhammer) was more to save Wheeljack. Miko didn't show remorse for killing Hardshell, but neither did she find satisfaction of her actions. Miko proved her bravery by confronting Soundwave himself singlehanded in Deadlock using the Apex Armor. She would do whatever it takes to prove herself and save or help her friends. She is also an arachnophobiac, that is, she is afraid of spiders.

She shows little regard for authority and rules which once led her to cut detention in Deus Ex Machina.*
