泰拉瑞亚里击败肉山boss掉落的破坏者巨剑是最终幻想7里克劳德的那把武器吗？

是的，我给你贴一段外网关于肉山破坏者巨剑的小花絮说明你就知道了：

The Breaker Blade is a reference to the Buster Sword from the game Final Fantasy VII, wielded by the protagonist Cloud Strife. The resemblance can be seen in the synonymous naming (Breaker Blade/Buster Sword), and the weapon's similar designs, including its red handle, very large size and wedge shape, and the two red and green spots near the base of the blade, which reference Final Fantasy VII's "Materia" orbs that can be inserted into weapons.

The spots being red and green means that in the Final Fantasy VII, they would respectively be "Summon" and "Magic" materia.

机翻中文为：

毁灭刃参考了游戏“Final Fantasy VII”中，由主角Cloud Strife使用的Buster Sword。相似点可见于其同义的命名（Breaker Blade/Buster Sword），相似的设计——包括红色的手柄，巨大的尺寸，楔形的刀刃。还有靠近刀刃底部的红色和绿色的点，参考了Final Fantasy VII中可插入武器的“Materia”。

红色与绿色的点表示它们在Final Fantasy VII中分别是“召唤”和“魔法”的“Materia”。
