"This spider... is a bit fat." Negris couldn't help but complain. On the massive God Star, six short jointed legs were propped up, like a few toothpicks stuck into a rubber ball, completely out of proportion.
Ursman said, "It should have hit the limit of matter. The material manifested by Star Flame can't support a larger body."
Whether it's matter or energy structures, they all have their limits. For example, Brooks gathered the full power of the Dragon Clan to cast Tornado Storm, which could theoretically be even bigger, but the limits of energy and matter restricted its size, and in the end it only fought Tyrone's Typhoon to a draw.
Matter is the same. You can't build a thousand-meter-high wall out of bricks, because the bricks' own weight would crush the bricks themselves.
The bodies of Star Descendants, the forms of Star Flame Giants, and so on, all have their own limits. The material manifested by Star Flame is no exception.
