Masami Yoshida

Masami Yoshida (吉田正美, Yoshida Masami) is a supporting character in The Amazing World of Gumball. She is the spoiled-rich daughter of the owner of the Rainbow Factory. She made her first appearance in "The Third" when she is seen in the Schoolyard. Her first major appearance and role was in "The Pressure," where she pretended to be Darwin's girlfriend to impress the other girls.

Appearance
Masami is a small, white cloud with hollowed out holes for her eyes and mouth. In her promo pictures, she has eyelashes, but in the show, she does not. In early model sheets, Masami was colored half-light pink, half-white.

When afflicted with a negative emotion (such as sadness or anger), she turns gray and stormy. This has been seen on three occasions: in "The Pressure," where she cries when Darwin dumps her, in "The Party," where she zaps Gumball for insulting her, and most notably, in "The Storm," where she goes on a rampage for Alan's love. In this state, she becomes powerful and dangerous, wielding the ability to generate lightning bolts and powerful tornadoes, hurricanes, and other winds capable of smashing through solid concrete.

It was revealed in "The Gift" that Masami has legs, and that she wears long rainbow toe socks over them.

Personality
Being the spoiled daughter of the owner of the local Rainbow Factory, Masami is a bit of a snob. As a result of being so rich, she has a smug sense of superiority to her fellow students, taking every chance she can to show off. An example of this was in "The Pressure," where she forced Darwin to be her boyfriend to impress the other girls. She is seen throwing tantrums when she does not get her way, and threats to fire the parents of anyone who disagrees with and/or annoys her. Because a significant amount of the townspeople work at her father's rainbow factory, this threat could hold much weight.

She also seems to be a narcissist, being so obsessed with her appearance that she refuses to enter the pool for fear of her hair getting wet. More evidence of this was when she got jealous of all the attention Molly was getting for her treehouse. She immediately directs their attention to herself, and starts showing off, bragging that she has a boyfriend and they don't.

Masami doesn't seem to be able to take criticism well. When someone annoys or angers her, she sometimes gets gray and stormy and zaps whoever that person was with lightning. When she gets sad, she turns gray and starts raining, in other words, sobbing.

In "The Gift," it was revealed that Masami just wants to be treated like an ordinary girl, instead of royalty.
