Rachel Wilson

Rachel Wilson is a minor character in The Amazing World of Gumball. She is Tobias' older sister. She was Darwin's second love interest.

Appearance
Rachel's general appearance is similar to her younger brother and mother, but she more closely resembles her mother because of her humanoid stature, compared to Tobias' cloud physique.

Her skin is blue in color, and her hair fades from yellow to magenta. Like the rest of her family, Rachel has a headband on her hair.

Rachel's usual outfit consists of a white t-shirt, a chartreuse skirt that has a black shadow under it, and a pair of white sneakers with red stripes.

Personality
Rachel views herself to be of a higher class than Tobias and his friends, calling them "dumb loser babies" on some occasions, possibly indicating that she is somewhat discriminating towards her younger peers. At first, Rachel did not want to let Tobias' friends attend the party, but her brother warned her that if she did not allow them to be invited, he'd tell their parents, leaving her no choice. She seems to submit fast with blackmail, and makes a solution by simply allowing Tobias and his invited friends to come, only requiring them to bring a date in order to come to the party.

At the party, none of Rachel's friends showed up and as a result, she was crushed. Darwin, however, saw her crying outside (displaying a more sensitive side of her), and tried to comfort her by cleaning up the ruined house. Rachel seemed calmed by his offer and admitted that he wasn't so bad for a kid. Rachel was extremely happy, and gave Darwin a kiss on the cheek as a sign of gratitude.

Tobias
