Careful S. (character)

* Seasons 1-9
* Season 10 onward

*This article is about the character named Careful S. You may be looking for the episode of the same name.*

**Careful S.** is one of the main characters of *Happy Heroes*.

## Description

Careful S. generally appears to be emotionless compared to the other characters, and he doesn't like to talk much. Careful S. has the ability to create duplicates of himself to assist him during battles; a few episodes show he is also able to give the ability to the other Supermen. Careful S. is best friends with Kalo and often works with him in battles. He is often depicted trying to solve a Rubik's Cube. When he smiles on command, it is so unsettling that it scares people, and even monsters, away.

Early on in his existence, he hit his head really hard, and a specific wire connector in his head became loose. When this connector becomes fully disconnected (usually through blunt force trauma, such as hitting his head or an explosion), he loses his memories and can easily be manipulated into becoming evil. Since the connector was loosened early on, Careful S. seems to be more susceptible to mind control or brainwash than the other Heroes.

He represents fortitude of the black stone on Planet Qiyuan. His stone represents perseverance.

## Biography

### Season 1

Careful S. was the last hero to join the team, as his Jixie Stone was the only one Big M. still had with him.

The sentience which came along with the objects in which his Jixie Stone was attached to first showed capability of compassion in the last episode of season 1. When Big M. and Little M. infused it with a motorcycle, it swerved itself away from hitting an old lady crossing a street, despite wrecking itself in the process. Later on in the evening, Doctor H. tried to fix the motorcycle. Upon realizing that Doctor H. was in danger of being hit by an electricity pole that Big M. pushed over, it knocked Doctor H. out of the way, resulting in the electricity pole hitting it instead. The surge of power that it received from the electricity pole caused the motorcycle to transform into Careful S. in his Car Knight form. He gently set Doctor H. at a safe location and followed Big M. and Little M. away.

Careful S. in his Car Knight form continues to help Big M. and Little M. in their evil endeavors briefly by shooting away the delivery man asking for the delivery fee that the pair didn't have. He was summoned to ask the Heroes and Doctor H., but upon recognizing Doctor H. as the one who helped him, he opted to protect them instead. After a brawl with the Race Car Monster, he emerged out of the dust in human form. Smart S. yells "小心! (Be Careful!)" while Doctor H. says "超人? (Superman?)" Happy S. runs up to thank him for saving Doctor H., but he shoots him away with a laser from the orange circle on his hat. He introduces himself as 小心超人 (Careful S.).

### Season 2

#### The Trail of Careful S. Arc

He is welcome in the Doctor H. household and is popular among the Heroes, with Sweet S. and Happy S. fighting over him to spend time with him. Smart S. starts blossoming a petty rivalry with Careful S., as he realizes that Careful S. has unintentionally begun stealing his spotlight in some occasions. Later on, Smart S. and Careful S. save some civilians by being hit by malfunctioning aircrafts falling to the ground. Careful S. uses his duplication ability to destroy several aircrafts, but he misses one, and it comes straight at them. Careful S. pushes Smart S. out of the way to protect him, subsequently getting knocked into a wall by the aircraft himself. This causes a specific wire connector in his head to loosen. Smart S. later kicks a pebble out of frustration of Careful S. gaining more attention than him, and that pebble bounces off the wall and hits Careful S. in the head again, causing the connector to fully disconnect. Unknowing to Smart S., this causes Careful S. to lose his memories of himself and his whereabouts.

Careful S. wanders around the city asking civilians who he is, but no one knows. One person gives him the answer that he is his "dad's son," and he later gathers that his "dad" must be someone who looks similar to him. Due to this, he mistakes a robber as his father because of their matching black eye masks. He is disappointed to find out that he is not, in fact, his father. Later, Big M. attempts to use the remote controller that he used to use on the Black Jewel infused objects, hoping that he'll be able to control Careful S. again. With his weakened consciousness, it works, and Careful S. starts obeying his commands again. This also allows Big M. to convince Careful S. that he is his "dad."

Careful S. follows Big M. and Little M. to the shack they call home, where he robotically answers "Yes, dad," to their commands. He does their dishes for them in record speed. Big M. tells Careful S. to demonstrate his power for the Commander who is on video call with him, to which Careful S. obliterates their house. Later on, Little M. asks him to play a video game with him, which awakens a memory of Happy S. asking him the same thing. This causes him to question who he is again and have a mental breakdown before passing out.

Big M. and Little M. then take Careful S. to the base where the Blue Light Shield is operated and tell him to infiltrate it and deactivate the shield. He does so successfully, allowing a fleet of Planet Gray spaceships to invade the planet. Careful S. in his Car Knight form is deployed to fight the other four Heroes' Car Knights when they arrive to stop the fleet. The Heroes calling his name reawakens more memories, making him even more confused and enraged, so he begins attacking everyone. Soon after, a missile hits the Careful Car Knight, causing Careful S. to hit his head again on the interior of the Car Knight. This reconnects the disjointed wire connector in his head, allowing him to regain his memories. He destroys the rest of the enemies, and after the battle is over, Sweet S. asks if he remembers them. He confirms this by recalling that her food tastes really bad. Sweet S. runs off in tears, and the rest of them return home as well.

### Other Episodes

In "Separate Mutiny", he was split into five distinct versions of himself: Innocent Careful (天真小心), Ancient Careful (古人小心), Rebellious Careful (反叛小心), and Evil Careful (邪恶小心). According to Doctor H., the duplicates each represent a core part of his personality, and the longer they remain separated from Careful S., the more evident the duplicates' individual personalities become.

In the first film, Careful S. becomes temporarily mind-controlled into fighting Happy S. and Smart S. but was reverted to normal by the end.

After Kalo sacrificed himself for Planet Xing, Careful S. experienced major depression at the thought of his best friend being dead. It's discovered by Happy S. that he goes as far as writing an entire story in his notebook where he and Kalo swap positions and he dies instead.
