Henry in a way is like Matt, though personally I find him like a S-2 T.K.. Henry lives in Japan with his family. One day his father bought him a Digimon Computer game and Henry went to test it out. It seemed to be a fighting game and he had chosen Terriermon as his player. Terriermon was matched up against Gorillamon and the battle started. Through the battle Henry could see pain from Terriermon, it was strange connection and when Terriermon fell to the ground, Henry called out. A card in his hand transformed into a blue card and Henry scanned it through his Card Scanner that was attached to the computer. It changes into a D-Power and Terriermon is brought out of the computer to Henry. From that point on, Henry's life was never the same and his cute little sister Suzie got a new "Doll" to play with. ^_^ Henry is somewhat of the calm one in the group. He can be reluctant to jump into battle. He can also be quite protective of his friends and family. He shares a really good bond with Terriermon and the two are like two peas in a pod. Where ever Henry goes Terriermon will follow. He doesn't like Terriermon to battle, probably for the fear that Terriermon will leave.
Later though he really doesn't have much choice as his friends and family are put into danger. He met Takato through school and other strange events and they became friends. He's always backed his friends up somehow and that's a good thing about him. Near the end when the D-Reaper is loose, without knowing it, Terriermon get's the Juggernaught program in him and it stops the D-Reaper and saves the day, though at a cost, Terriermon and the other Digimon had to return to the Digital World. He hurt to see Terriermon leave him and was really upset with his father, who helped with the program that caused it. Though we know that it wouldn't last long.
