Why is Diga Altman always said to be "the strongest Altman"?

Because Diga Altman is the childhood of many people, which makes people miss it. Diga is not only the strongest Altman, but also known as the most positive Altman in Heisei era. So Diga is deeply loved by people. Diga is the strongest for a reason. Diga was the most powerful dark Altman in ultra-ancient times 30 million years ago. He destroyed the ancient times and finally abandoned the darkness. Diga's own form is more general than other Altman's. But Dijia's strength comes from people's hope and the light in their hearts. The stronger a man's faith, the more invincible Diga is. At the end of the TV version, the children's hopes turned into light, giving Dijia infinite strength. Other Altmen rely on material strength, while Diga relies on spiritual strength. Diga is originally the Altman on the earth, so it is different from other Altmen. Finally, TV tells us a truth: people should have hope. ! !
