Alice "Gramma" Delores Green (born October 10, 1943) is a main character in Big City Greens. She is Bill's mother and Cricket and Tilly’s paternal grandmother, as well as the matriarch of the Green family.
She has the appearance of an elderly woman. She's shorter than Bill, has wrinkles, has light blue hair (brown when younger), and her head shape is notably square, with a face like a bird's. As shown in Space Chicken, she has a wooden prosthetic leg in place on the right.
She mostly wears a long pink dress which mostly covers much of her height, she wears a pearled necklace, black round glasses with light blue lenses, and wears pink furry slippers. She also carries a cane, she also has a hearing aid on her left ear.
Gramma Alice is quite a cranky and mean person, but deep down is sweet and caring. Hardened by her service in a war  she can be described as someone who is "tough as nails".
She is also shown to be very caring for her grandson, but can't stand his antics sometimes. She may participate in whatever thing he has planned. An example is in "Photo Op" where she goes with his plan to sneak to the food court.
Both don't usually interact much as she does with Cricket and Bill, but they seem to have a decent relationship. In "Tilly Tour", Tilly takes Gramma on a tour around Big City so the latter will start to like it.
Both don't usually interact much as Remy does with Cricket and Tilly, but they seem to be on good terms. In "Cricket's Shoes", she fills in for Cricket to play on the trampoline with Remy, and she starts to realize why Cricket likes hanging out with Remy.
Mr. Grigorian has been enemies with Alice for some amount of time, and it is currently unknown why this is the case. Even after Mr. Grigorian cleared things up with Tilly, he is still enemies with Alice. ("Forbidden Feline")
These two do not interact much as the other Greens with Chip, but as with the other Greens, they are enemies with him. It is only in "Reckoning Ball" that they drop this and opt to show their true selves as caring people. It can also be mentioned that Gramma and Cricket were the two Greens who were cautious of Chip's deep down true, malicious intentions, hesitating when it was time to sign the contract.

According to the creators, Gramma Alice was heavily based off of the creators' grandmother, who had the same name and personality when they describe Alice.
They claimed that she's a tough, but sweet lady.
Some early artwork of the series depict her in a wheelchair.
Her right leg is worn in a prosthetic attachment ("Space Chicken").
It is unknown how Alice lost her leg. In "Winner Winner", she claims that she danced it off, while in "Hurty Tooth", she says that a doctor "took it" from her.
Some episodes (e.g. "Cricket's Biscuits", "Elevator Action") have Gramma mention that she had done at least some service in a war. It is unknown which war she served in.
"Cricket's Biscuits" has her use a device she had not used "since the war". One can assume that she used to be a nurse.
"Elevator Action" reveals that she had also done "enough flying in the war"; one can assume that she was an Air Force pilot, too.
In "Gramma's License", she used to be a race car driver as she won a certain amount of trophies.
While in the same episode, she drove a sliver but worn car which after it got towed, the car was never seen again after the episode.
She had a driver license that was so old before being vanished, it had some information such as:
Her street address
Her Date of Birth was October 10, 1943.
She is the first character whose birth date has been revealed.
No one else calls her Alice, except Nancy.
Alice seems to possess a wide variety of antique weapons, the most notable being a sword and a club and in "Fill Bill" she claimed to have owned a trident at one point.
Alice apparently has access to a large sum of money, but claims she cannot get it because it is "tied up with the Feds" ("Steak Night")
In "Gramma's License", Alice is revealed to have been born on October 10, 1943. If the episode took place on June 22, 2018 (the day the episode aired) that would mean that Alice is 74 years old. This would also mean that by the time "Blood Moon" occurred, she had just turned 75.
Alice apparently objected at Bill and Nancy's wedding, but was ignored. She has since shown a lot of animosity towards her, though in "Cricket's Biscuits", she has been kind to her in the past.
In "Cheap Snake", Alice is revealed to suffer from severe ophidiophobia, the fear of snakes.
