Elasgen

In a world that is full of beast tamers, Samuel who lives with his sole parent, his father, is faced with a crisis when their village is attacked.
It's on this occasion that he finds out that his father was also a beast tamer. But his strength was not capable of dealing with the beast that had attacked.
His beast is killed and he suffers a backlash that leads to him being bedridden. As for the beast that attacked, it retreated after killing almost all the villagers.
During his father's dying moments, he reveals that Samuel held a deep power within him and that he should go out and explore it. They had hidden in that village for over 18 years, to avoid the exploitation of his talent.
As he finally leaves the village for the first time as long as he could remember, he finally ventures into the world, with a big secret hidden within him.

The Ancient Beast Tamer Bloodline

After thinking for a while, Samuel finally came to a decision. Hit me better a beast that would be able to defend and attack at the same time. Even if there was no balance between attack and defense, at least 1 of the areas had to be its main point of focus.

If he could find a monster that was capable of attacking and defending at the same time, then things would work out well for him. That was especially if the beast was capable of explosive attacks and dealing a lot of damage.

He was not looking for a monster that was capable of launching attacks in a wide area, but instead, he just wanted 1 that could focus on a single target. If it came to a large scale attack, then that would have to be left to Thunder.

While Thunder's destructive capability was not that high as compared to some of the beasts, he still possessed lightning nevertheless. For that reason, Thunder would be able to deal quite some damage, especially if the targets were at a lower level.
