Xia Ya's NT ability is not as good as that of Jiedu, Camus and Amro, but its comprehensive ability is strong. Commander-in-chief ability can compete with Lundbell Fleet (the main force of the Earth Federation at that time) with the strength of New Keon, which shows that Xia Ya's commander-in-chief ability is very strong.
Its operation technology was very strong in the early generation, but it lost to Amro. Gundam Z used 100 kinds of energy to fight against Shillock+Harman, two top NT and top organisms at that time. 0 and white cards. In the early melee, Titan and ace did not fall behind, or even fell behind. (Bai Shi is not an air combat body, so the air combat performance is poor.) It is worth mentioning that the leader of Bai Yalan, who is unparalleled in UC, was once the Titan's ace, which can also reflect the combat level of the Titan's ace troops. In 0093, Amro 55 was used again, but it was defeated by hawthorn cake because of its poor battery life.
He is also outstanding in politics. From Z, he can show his excellent speech level and charisma as a leader. Later, he led Gu Ao ·AEUG to fight against Titan and finally won. It is also because of the tragic ending of Z Gundam that Xia Ya is disappointed with the Earth Federation.
The fake duck is just a clone of Xia Ya, whose NT ability is not as good as that of Xia Ya, and even he may just strengthen the world in the end. The operation technology should be comparable to it. The performance of Xin 'an House has far surpassed that of Hawthorn Cake, but the defect is that the new Keon is too mobile and was crushed by an NT fist. But it doesn't mean the fake duck is weak. I can only say that he is not as good as garbage in the later period.
