Charles is a young and experienced pilot for the Government. In the Triple Threat route, he is able to stop his chopper mid-flight so the rotor blades don't chop up Henry Stickmin and Ellie Rose as they leave the sabotaged rocket. This is an incredibly difficult maneuver to pull off and he does it easily. Charles, Henry and Ellie each share a mutual friendship in Triple Threat and are all friends in Pardoned Pals. This is because, "Any friend of Henry's is a friend of mine."

Because of his abilities as a pilot, General Hubert Galeforce seems to always trust him with missions despite his history of hilariously failing to assist Henry, most famously when he crashes his helicopter in two fails. Despite his silliness and accident-prone tendencies, Charles is easily one of the more noble characters in the series, and is even willing to sacrifice himself for his allies as shown in the Valiant Hero route.

His answer to any problem he and Henry encounter throughout the series is to crash his helicopter into it. While it normally ends badly, in Completing the Mission, this both works for and against him when the resulting crash critically damages the station's core, leading to a series of events that results in Charles being unable to escape the station with Henry.

Compared to both Henry and Ellie, whose morality are dependent on the players' choice, Charles is the only one in the main trio who's outright noble and heroic from the get-go. As such, Charles will only help out Henry in routes where he aligns with the Government.

Charles has a tendency to try and make small talk and stumble his words which shows that he's more sociable than Henry and much more nonchalant about missions despite the known severity of them. He also has plenty of background knowledge on Government weapons and other such tools.

If Henry sides with the Government, Charles shows complete confidence and trust in Henry in any missions they team up in, showing how loyal he is to a close friend. He is also shown to take things literally at times, demonstrated when he shut the power of the Airship off when asked, without realizing the airship needs power to fly.

Charles is amiable, sociable, half-witted yet intelligent, and an above average pilot who firmly sticks with his side, but does have a more open mind considering he put his faith in Henry in the Pardoned Pals route despite Henry going rogue and stealing the Romanian Ruby, and gave Henry a chance to side with him over joining the Toppats or surrendering to the Wall.

Charles is also able to remain calm in stressful or dangerous situations, keeping his composure and not sounding worried. A good example of this is in the Special BROvert Ops route, where he loses control of his helicopter while trying to snipe someone, and doesn't sound panicked in the slightest while trying to regain control; Henry actually looks more worried than Charles sounds. Charles is also very optimistic as seen in the Valiant Hero ending, where he assures Henry that he will find a way out of the Toppat Orbital Station, which is about to explode.

He is also shown to be easily distracted as shown when he comments on a duck flying into the airship’s propellers, inadvertently blowing Henry’s cover, without him realizing this, indicating that he is not always focused on the present situation. Charles wears a red headset throughout all his appearances. It is shown in Special BROvert Ops and Valiant Hero that Charles has red shoes. His headset suffered damage in Valiant Hero due to Charles crashing into the Toppat Orbital Station.

He has never been seen without his red headset. The headset has been shown to be a versatile communications device; able to call in reinforcements and communicate directly with phones.
