Infiltrating the Airship
He controls the military helicopter and leads Henry through his mission.
In the GSPI ending, when Captain G sends Henry on his mission, Charles gives him an earpiece and serves as Henry's handler. After Henry breaks into the airship, Charles helps him cross a large gap by using a mechanical robot. The next room has a guard who is having trouble using his keycard in the door. Charles assists Henry by using one of his gadgets to melt the officer's bones. After Henry gathers the evidence he needs, Charles reveals the next room has too many armed guards, and suggests Henry too use the ventilation duct. There is a lot of electricity blocking the path, but Henry orders Charles to reroute the power to a random room (that ends up being a darkroom, ruining the photos of the Toppat Clan Member working inside) Henry can now safely reach the cargo bay, where two more men are blocking his path. Charles thus tells Henry to click a button on his earpiece, which turns it into a force gun. Henry takes out the two men and Charles brings the chopper near the bay doors. The Right Hand Man comes into the cargo bay and attempts to stop Henry, but Henry is able to use the force gun to blast himself to the chopper. He turns the evidence over to Charles, and the Toppat Clan is arrested.
In the PBT ending, when Geoffrey spots Henry who steals the ruby, Charles sees that alarm is activated and Henry has been found out. Captain G moves to plan B and Charles calls reinforcements. Military soldiers then break into the airship and cause it to crash in the desert, where the fight continues on the ground. When the Center for Chaos Containment launches a prototype army to solve the chaos, Henry steals their armor and escapes with the ruby. Charles intercepts him, but the Captain tells him to let him go over Charles's protests.
In the RBH ending, Charles isn't seen until the end. After turning over the Toppat Leader to the General, Charles hands Henry a document pardoning him of his crimes. He and the General take the Toppat Leader and leave.
Fleeing the Complex
Charles reappears in Fleeing the Complex. If Henry escapes his cell, he has the option to contact Charles. Charles remarks that he is on another mission, but has heard of The Wall and can swing by to get Henry out. He then instructs Henry to head outside and find a place for him to land. A guard blocks Henry's way, but Charles clears the path by controlling a miniature helicopter to latch a grappling hook to the guard, pulling him off the ledge. When Henry continues to the helipad, the two guards up there spot his helicopter and prepare to shoot him down. Henry tackles the one with a rocket launcher to save Charles. When the other guard notices Henry, he is crushed by Charles' helicopter. The two of them then fly off, earning the rank: International Rescue Operative.
Completing the Mission
Charles is set to appear in the final game.
Charles is not very intelligent. In both games that he appears in, he has the "perfect plan" to deal with enemies, namely fly his helicopter straight into them, despite the risks and obstacles. Most of the fails in the route where he assists Henry fails because he messes something up. He really likes using a gatling gun, but ends up accidentally killing Henry with it because it was poorly suited for the scenario. He does pull off a masterful shot in Complex with a sniper rifle, but unfortunately, he accidentally aimed at Henry instead of the guard.
Charles also doesn't understand many of the gadgets he uses. He has a gravity bubble, but has no idea if "Up" means that it raises the gravity inside the bubble, or lift the person in the bubble up into the air. He'll also hack into their systems to open a door not realizing it's the wrong one. He also takes things very literally: He'll shut the power off the Airship when asked, but doesn't realize the airship needs power to fly.
If the Rapidly Promoted Executive or Pure Blooded Thief ending are considered canon, he might have a great bond with Henry and always treat him as his partner despite Henry's actions opposing the government he's working for, as he's willing to help Henry escaping the complex. He also feels bad if he accidentally shoots Henry.
