V-Tamer is a manga version of Digimon that was never really released in English, but various sites have talented people who have actually posted a translated version of this great series. Based on the original Digimon V-pets, V-Tamer certainly brings a whole new twist on the world of Digimon. It opens with Taichi, the main character of the series, attempting to enter a tournment with his V-pet, only to be disqualified because the monster on his V-pet cannot be identified and therefore was not a Digimon that was supposed to be programmed into the V-pet.

A short time later, Taichi finds himself in the Digital World and meets up with his Digimon, Zeromaru, or just Zero for short. Zero is a V-dramon (Veedramon), and between himself and Taichi, they have a battle record of 100%. For this reason, the two of them were chosen by Holy Angemon to save the Digital World from the supreme evil, Arca Demon. With the help of their guide, Gabo, Taichi and Zero set off to defend the Digital World from Arca Demon.

Taking place on the fictional continent of Elibe and stars Roy, the son of Fire Emblem protagonist Eliwood. Roy leads the League of Lycia's army against the forces of the militant country of Bern shortly after his father falls ill.
The story begins when King Zephiel, ruler of the kingdom of Bern, finishes the brutal conquest of Ilia and Sacae and sets his sights on Lycia. With the war coming to his own country, Roy is sent home to lead Pherae's army to oppose Bern, but soon after he meets Guinevere, the princess of Bern and Zephiel's younger sister, who has escaped from her homeland to search for a way to stop the imminent war between Bern and Lycia.
Upon the death of marquess Hector, Roy carries on the Lycian League and makes many promises: to protect Princess Guinevere and Hector's beloved daughter, the mage Lilina, and most importantly, to save the entire continent from Zephiel's mysterious thirst for world domination.
But this story's hero is Al, son of a Bernian blacksmith. After turning 15 he left his home with his father's sword to go on an adventure in this continent bound for war.
