Because giants belong to the form of attacking giants. Allen inherited the power to attack giants and ancestor giants from his father. However, because the power of the ancestor giant can only be brought into full play, even if Allen got the power of the ancestor giant, he still could not play the coordinates of the ancestor giant, so he could not use the ancestor giant form.

The Emergence of Allen's Ancestor Giant

Allen's ancestor giant was huge, several times bigger than the super giant, with almost no meat and bare bones. The most familiar attack giant should be the giant of early Allen, followed by the giant of Grisha Yaeger, Allen's father, who summoned a giant with a huge body and thick chest hair.

Allen Kruger is the first successor to attack the giant in the play, and the giant summoned by him is very handsome. His face is almost an enlarged version of Alan Kruger himself, and Allen's ancestor giant form finally shows its true colors for the first time. A giant composed of bones, many times larger than the Ming Di giant, appeared in the air of Malai. Judging from the huge face exposed, this is undoubtedly the ancestor Allen.
