Ren Takachiho (Earth-101001)

Ren Takachiho (レン・高千穂 Ren Takachiho) is one of the deuteragonists in the Kingdom Hearts (2015 TV series).

Appearance
Ren is a young boy with tanned skin, messy black hair, and black eyes. While living on his birthplace, he wears a black hoodie, white sleeveless shirt, with loose dark grey cargo shorts, and sneakers.

In his costume, while living in Hollow Bastion, he dresses in a pale amethyst, sleeveless shirt, with loose dark blue shorts and a brown belt, brown wristbands, and sandals. He also wears a green cloak with three white and red feathers around the lip and white leg warmers. He wields a large red and white boomerang and uses cyan warpaint on his face.

Personality
As opposed to the other conduits, Ren did not live in the human world, nor did he originally have a particular liking for it. Though originally born on Earth to scientists Tadashi and Aiko Takachiho, he was accidentally transported to Hollow Bastion as an infant and was raised by Luma and Meruka.

Ren, like most archetypal wild people, refers to himself with a "me" instead of an "I", despite the fact that the Bakugan he grew up with has a proper vocabulary. He believes in defending the peace of Vestroia, and also initially believes that humans are nothing but a threat to it. Despite his young age, Keenan has a great fighting skill (many of his moves mirror the ninja-like aspects of Hawktor). He wields a boomerang, and wears a cape and a necklace adorned with feathers, and also has facepaint.

Biography
After Ren was transported to Hollow Bastion, he was raised by a Hawktor and was protected by Hawktor. He was sickly as a young boy; at one point Luma went to find medicine left behind by humans that had been in Hollow Bastion. But after nursing him back to health, the evil scientist Kurata came to Hollow Bastion to try and annihilate the Bakugan and people in an act of genocide as searching the two cores and 6 Infinity Stones. Though Kurata was eventually defeated, he was able to send A.I.M. to kill many people and Bakugan, among them, was Ren's foster mother, who was killed before his very eyes while trying to protect him. This event was crucial to Ren's hatred of humanity, as he came to believe that all humans were evil and became dedicated to defending Hollow Bastion from them. From this point on, he was raised by Meruka.

Ren (also known as Daichi) first appeared in the series' eighty-three episode, where he attacked the members of the Fusion Tenders as they emerged into Hollow Bastion. His initial attack destroyed the equipment they had brought with them, effectively stranding them. To their surprise, he revealed that he is a conduit, which he then summoned Hawktor. The two overwhelmed the Tenders until their battle was interrupted by an angry Kijimunaa, who was enraged by the fact that their battle was endangering the Nyoki he was protecting. When Gotsu, one of Meruka's servants, began to rain massive rocks down on the area, Daichi and Hawktor fled.

Daichi intended to attack Tomoe, who had fallen ill and contracted a virus, but Daichi instead contracted the virus himself. Hawktor forged an uneasy alliance with Thomas and Marcus to retrieve a vaccine, and saved his partner. He and Keenan later departed on their own. Keenan reveals the reason for his hatred of humans to Marcus in episode 17. A mysterious group of humans (later revealed to be Kurata and his strike force) destroyed his Digimon foster-mother, Frigimon, and he cannot forgive the humans for what they did. Believing himself to be a Digimon, he now attacks any human he comes across. However, while battling with the DATS members, he slowly gains a new perspective of humans, and is actually impressed with some of their kind and honorable acts. He is especially taken by Marcus, who seems to actually care for his well-being, despite their initial hostilities, and with his ideas of nobility and honor.

The events of episodes 18-19 forced Keenan into the human world against his will. It was there that Keenan learned from DATS's commander, Commander Sampson, of his birth parents, the Crier couple. Keenan, the son of Kevin Crier, was sucked into the Digital Gate by accident when he was a baby. Though Kevin and his wife participated in a Digital World expedition team in order to rescue Keenan, they never found him. Keenan, with urging from Marcus, decides to meet them, but Gotsumon makes that difficult with three Okuwamon; two were defeated by RiseGreymon and Lilamon. A Hagurumon then appears and takes over Mr. Crier's home by using his Darkness Gear on a toy robot (left over from Keenan's childhood) which merges with the house and then uses the memories that Keenan had of the toy robot and transforms it into a bizarre, giant, toy-robot house with Michelle Crier trapped inside. Hagurumon's face was seen as the left eye of the robot. Michelle was rescues by Keenan and Falcomon. Hagurumon was destroyed by RiseGreymon. Thus the toy robot his gear merged with returned to normal.

Even though he was briefly reunited with his mother, Keenan's memories of Frigimon (who Keenan regards as his mother) were still etched in his mind. Though he realized that he loved his human mother as well, his human father warned that his presence may upset his mother, who had to undergo a lengthy and hard recovery from his initial disappearance. In addition, the Criers now had a second child, Keenan's baby sister, Ruka. Suddenly, Sampson's superior, Chief Hashiba, whose department oversees DATS, appears and tries to declare the Crier family as criminals for secretly researching Digimon and opening a Digital Gate. In order to save his human family from imprisonment and keep his infant sister united with his parents, Keenan ultimately denounces his humanity and takes the blame as he runs off with Falcomon, saving his family from prosecution. Marcus and the other DATS members become extremely angered at Chief Hashiba for his actions.

Matters get worse when Gotsumon appears later leading SaberLeomon's army of Boarmon and Pteramon in an onslaught against the city unless Keenan is brought before him. Gotsumon now sees Keenan as a traitor to the Digimon and wishes to destroy him and Falcomon for what he sees as collaboration with the humans. The DATS members flatly refuse and wage an all out war against the invading forces. Keenan, filled with grief and worry for his new friends, eventually pops up to help them. After that, Marcus moves Keenan in with his family, and acts as surrogate big-brother towards him. Marcus's family and the other DATS members also try to help get Keenan settled, all the while hiding his presence from Chief Hashiba.

When Marcus and company set for the Digital World to meet Merukimon and propose peace between Earth and the Digital World, Keenan remained at home. But after much thought and soul-searching, he decided to follow them and them obtain the peace they, and now him as well, wished for. However, the mission goes wrong when Kurata, under false pretenses of peace, attacks Merukimon using Gizmon XT, which is under his control. It is then that Kurata reveals the truth about Frigimon's death and that he is the real culprit. Merukimon is mortally wounded by one of Kurata's Gizmon XT. Keenan is moved by Merukimon's last words, realizing that the only humans he must fight are the evil ones, and also realizing that Frigimon wanted him to live in peace with both his human and Digimon natures. His digisoul awakened further allowing him to bring Falcomon to his Ultimate level, Crowmon. With this new power, Keenan managed to save the DATS team who were now engaged in battle with Kurata on Keenan's behalf and were about to be defeated.
