What's Kaidou's fault is that Gaban, an insanely well-known and legendary figure, is considered by the people that in a 1-on-1 match, Kaidou will beat him?
What's Kaidou's fault is that 10 years after God Valley, they began to consider him the very personification of strength, while Gaban, a legendary and popularly known figure, was wandering around in his prime.
Or WSC.
Or strongest in the world.
