Denshii, an old character I had during middle school and some of high school.
She had electric and magnetic powers and could run really fast.
I always associated speed with electricity because in Pokemon most electric types are fast.
The idea behind her was to be fast like Sonic but to be cute like Kirby.
She would go around zapping enemies purely for fun. (Even as a kid I liked cute, violent things.)
And when she slept she would plug her tail into a socket to recharge (Kinda like Chibi-Robo.)

Her name was combination of a few things:
The Denshi Bunny from Xialoin Showdown (I was a huge fan at the time)
but with two 'i's like the Wii (Because it was a huge thing around the time of Denshii's creation).
I didn't know it back then but Denshi translates to "electron" in Japanese, so that fits.

I used to draw her all the time as a kid. It's been almost 9 years since I've drawn her, though.

I don't know. I'm feeling nostalgic today.
