Pike is a tan man with beady eyes, a flat nose, thick lips, thick eyebrows, and rounded teeth. He also has scruffy brown hair and a goatee. He wears a brown shirt, blue pants, black boots, a brown cloak with "G-5" printed on it, and a standard white Marine cap that is turned on an angle.

Pike is a very valiant person, having high respects for his sacrificed comrades and vowing to protect his captain, Tashigi, for them. He is also quite level-headed, trying to convince his captain that their comrades' sacrifice must not prevent them from continuing with their mission to rescue the children and capture Caesar Clown.

Pike is very easily smitten by beautiful women, as shown with his relationship with Tashigi and, later, when first interacting with Monet.

Abilities and Powers
Pike hasn't shown any particular ability in combat. He does carry around a rifle, but it is unknown how skilled he is in using it.

Fishman Island Arc
When the G-5 Marines were being attacked by an enemy pirate crew, Pike and the other Marines cheered Tashigi on as she protected the ship.

Punk Hazard Arc
Pike and the rest of the G-5 Marines traveled to Punk Hazard.

After the minds of Smoker and Tashigi were switched, the G-5 Marines were quite disturbed. Pike, in particular, exclaimed that he couldn't handle Tashigi being in Smoker's body. He, along with the rest of G-5, was told about a spy in their ranks who was covering up the child kidnappings and that Caesar Clown was responsible for the actions on the island.

When some of the G-5 Marines were fighting Smiley's spawn, Pike watched from a distance as his comrades them on fire, causing the ship they were on to explode. Pike, as well as some of his comrades and some of the Straw Hat Pirates, were shocked and horrified by the event.

After a fight with the Centaur Patrol Unit and the capture of Smoker and Tashigi, the G-5 Marines were left outside the laboratory. When their superiors were placed in a cage outside and the Shinokuni began spreading, they asked Smoker and Tashigi what to do.

Trafalgar Law hatched a plan to escape, and, afterwards, opened an entrance for the G-5 Marines to enter. Pike and his comrades were shocked that an entrance was opened and that they would be safe from the Shinokuni. However, the rest of the Straw Hat Pirates and Brownbeard broke down the closed door to get in, also causing everyone inside to be put in danger.

The G-5 Marines, knowing that the Shinokuni would enter the lab, pushed a massive piece of metal into the hole made by the Straw Hat Pirates to plug it. Law then told everyone inside his plan to capture Caesar. The G-5 Marines followed Tashigi to find the children.

Pike, along with the rest of his branch, decided to defend against and attempt to capture some of the Straw Hat Pirates. There was a short struggle, but Tashigi stopped it, explaining that both parties had the same goal. The branch and crew rushed to enter the closing gate to the entrance after Shinokuni began leaking into the building. Pike managed to escape and, when he turned around, he saw that his captain, Tashigi, was thrown through as the gate was closing. He caught her and, shouting through the closing gate, thanked his comrades for protecting their captain.

Pike and the other Marines tried to convince their captain to continue searching for Caesar, despite the loss of their friends. At that moment, Vice Admiral Vergo entered, causing the G-5 Marines to cheer, thinking that Vergo had come to help. Swiftly, the Vice Admiral attacked his subordinates, revealing his betrayal. Pike, as well as the rest of the branch except Tashigi, was defeated by Vergo, leaving the Vice Admiral to fight Tashigi. Before Tashigi was defeated, however, Sanji arrived to protect her.

The G-5 Marines regained consciousness as the pirate and Vice Admiral fought. They hurried to save their injured comrades and captain as another set of gates was shutting while Sanji and Vergo continued to fight. When there arrived at the other side of the now closed gate, the Marines panicked over Sanji, thinking he was on the other side. They then asked Tashigi if the "Vergo" they fought was an imposter. Tashigi lied them, saying that he wasn't the real Vergo and insisting that they hurry to save the children.

The Marines and Sanji continued through another room which had just been wrecked by Vegapunk's small dragon and the other Straw Hat Pirates. The Marines were complimenting Sanji on attacking the "fake Vergo" when, all of a sudden, a hole blew through the wall, letting in the Shinokuni once again. A few more Marines were frozen in it while the rest continued to run. Sanji began kicking the Marines to safety, causing them to complain. Ignoring their complaints, the pirate demanded that they continue to Biscuit's Room.

After arriving in Biscuit's Room, Pike pointed out to Sanji that the children were gone and that Zoro was fighting Monet. He and the other Marines insulted Zoro when told to do so by Sanji. When Monet, however, began attacking the Marines, Tashigi demanded that her subordinates leave, saying that she was to fight the harpy. The G-5 Marines followed Sanji to save the children as the pirate explained his belief in not harming women and his confidence in Zoro and Tashigi's abilities to defeat Monet.

The G-5 Marines and Sanji continued their search until they arrived to the group of violent, drug-hungry children and some of Sanji's crewmates. He ordered the Marines to hold down the children and sedate them. They then carried the greatly injured Mocha to have her treated. They assisted the recovering children and assisted in Chopper's treatment of Mocha. The Marines and Straw Hat Pirates ran with the children to escape the approaching Shinokuni after the children recovered enough to run.

After Law cut the entire laboratory, the G-5 Marines and children we greatly exposed to the Shinokuni. They were quickly reunited with Zoro and Tashigi, who had been running the wrong way. The group continued on, running away from the oncoming gas.

Chopper and some of the G-5 Marines came across Brook and a frozen Kin'emon, shocked that the samurai had been caught by the Shinokuni. The rest of the Marines and the Straw Hat Pirates came across Luffy, as well as Law and Smoker, and, together, found a large rail car to transport everyone out of the laboratory.

All pf the G-5 Marines, Straw Hat Pirates, children, the remainder of Caesar's men, and Law loaded into the rail car. Chopper, the rest of the Marines, and Brook arrived through a closing gate at the last second. The entire group began to leave the laboritory in the car as the Shinokuni followed. The group continued to travel in the rail car, but the tunnel they were traveling in began to collapse. The Straw Hat Pirates protected the Marines and children by destroying the falling rocks to prevent them from crushing anyone.

Once the group got outside, they saw Franky Shogun fighting Baby 5 and Buffalo. The Marines were very impressed with the creation and watched as Nami and Usopp defeated the two and captured Caesar.
