Mtoto's Mom is a rather short elephant in comparison to the rest of her herd. Her skin is gray (with a very, very slight tan tint) with light gray toes. Her white tusks are short and her eyes are dark brown. Her inner ears are pink, with a small notch in her right. She has three dark gray spots on her back - one big, two small.
Whilst caring, Mtoto's Mom displays sternness when necessary, such as when her son does not return on time. She is also easily moved to irritation, as seen when Bunga constantly forgot his lines during a rehearsal for the Ukumbusho. When panicked, she is capable of going on a rampage and losing track of her own whereabouts. But she is also willing to listen and be calmed, taking advice from others when necessary. She is appreciative of those who help her.
Mtoto's Mom attends Aminifu's funeral, dropping a flower off at his body. When King Simba begins his speech, she hears his mistake. Although she is at first shocked, she soon starts to laugh with the rest of her herd, seeing the bright side of his joke.
Later, they perform at the celebration, before joining the rest of the animals gathered at Mizimu Grove. But during the celebration, Reirei's Pack attacks, frightening her. With King Simba urging everyone to stand together, she and the other animals successfully drive the jackals away.
Mtoto's Mom can be seen with her son, as well as several other elephants from her herd during "My Own Way". Fuli dashes past them and comes to an abrupt halt, facing them as she sings. She and her son sing in tune with Fuli, before she continues.
When her son Mtoto and his friends are playing nearby, they pretend to be hyenas. Overhearing the warning of a hyena in the area, Mtoto's Mom and several other animals become frightened, and huddle up together until the Lion Guard calm everyone down.
Mtoto hears his mother calling for him via infrasound, and she asks for him to be home by sundown.
After Makuu deems the plan worthy of a crocodile, Mtoto hears his mother calling for him again. After bidding goodbye to the Guard, Mtoto rushes off.
But the hyenas soon return, this time attacking the baboons that have begun to follow the elephants. Kion and Ono lead them to a dead end, where Kion can perform the Roar of the Elders on the hyenas, sending them back to the Outlands for good. Big Baboon leaps onto the head of Mtoto's Mom to speak with her leader.
Later, Mtoto's Mom walks around Ma Tembo, hoping that she will find water soon. Once Makini manages to calm everyone down using shwari, she is able to do so, allowing Mtoto's Mom to drink.
Ma Tembo's Herd are in charge of the Ukumbusho celebration, and Mtoto's Mom is chosen as the bravest for the show. When the Lion Guard arrive at Mizimu Grove, Mtoto races over to inform his hero that he will be playing the strongest elephant, while his mother takes the role of bravest.
However, when things go wrong, Mtoto's Mom voices her concerns over not rehearsing her line with Bunga, a piece which Ma Tembo considers to be the centerpiece of the show. The honey badger soon begins to rehearse with her, though constantly forgets her line, which annoys her. But when King Simba arrives, she has no choice but to go on with the performance. Worried about her lack of sunburst, Makini quickly hops onto her back and paints it for her, and the show begins.
Eventually, Mtoto's Mom leaves the rest of the herd, and rampages on Mapango Cliffs. After finding her, Bunga bounds up the cliff, and leaps onto the rampaging elephant's head. He eats the bees, which causes her to become aware of her surroundings. As she panics, Bunga soothingly reminds her of her lines, and that they're the bravest. This calms her, and they head back, narrowly avoiding the cliff falling down.
They return to the grove, where Ma Tembo is persuaded to start a new version of the show, where paint is not used. After reminding everyone that her paint is still on her forehead, Mtoto's Mom has her paint sprayed away by her son. She then reminds Bunga not to use her lines, but he makes no promises. They enter the show, which has started fresh.
When Bunga wants to give his uncles the best Christmas ever, Mtoto's Mom agrees to join in with the celebrations. After rehearsing all night, they are about to give up until Bunga reveals to them how important it is to him, and why.
When their home got destroyed by a fire by Scar's minions Kion must find a new place for them to live. As Kion's options don't work out she follows Ma Tembo as they start to leave the Pride Lands. But before they can go she and her herd are approached by Kion asking for their help Ma Tembo agrees to help while she stays behind to watch over the young ones.
