[Destined_Fate]

No, he was disarmed(Literally) by Kira who took advantage of his surprise appearance. When Shinn has his round 2 he completely demolished Kira.

Back on my other point. The Destiny was made to be the Ultimate Gundam of its series just like the Zeta was the Ultimate Gundam of its series. Shinn was to be the modern day version of Kamille, however things are different from back than. Had Zeta come out in the day and age that Destiny did than Kamille, who was just as rowdy and disobedient as Shinn(Even more so since he was literally punching everyone out that pissed him off), would have developed very differently and the calls for Amuro's return would have been deafening just like the calls for Kira were. Thus his role would have been expanded to the Lead role at the cost of Kamille. This would have ruined Kamille since like Shinn he was still developing at that point and like Shinn hadn't even gotten his upgrade when Amuro appeared.

This is reinforced more by the fact that the jump between the Impulse to Destiny(Just like the jump from Gundam MK.II to Zeta was huge) was staggering in scope while the Infinite Justice and Strike Freedom just looked like Justice and Freedom with a few more things tacked on. It's obvious that they had wanted to push Athrun into the role of Quattro(With Saviour being his Hyaku Shiki) and serve to mentor Shinn(Though they managed to remove the reason why Char worked so well with Kamille when they pushed Athrun to this role and instead of a mentor role he came off as just abusive and cruel to Shinn). With how rushed Strike Freedom was(It was literally just New Freedom that took beam spam to the 11) it's clear they hadn't planned to hand Kira a new Gundam just like Amuro didn't get a real upgrade in Zeta.

Kira was supposed to end up the bad ass Amuro of Destiny who did important things but didn't steal the show like Amuro didn't steal the show from Kamille since Zeta was Kamille's story just like Destiny was supposed to be Shinn's story not the Continuation of Amuro's story or Kira's story. Obviously this angered fans that "liked" Kamille but they wanted Amuro to be the lead anyway because he was the "Original" Bad ass. Since that was a long time ago the movement to dethrone Kamille and put Amuro back in the spotlight was unorganized(Though not any less zealous) compared to the massive, and organized, outpouring to replace the Likeable Shinn with the even more Likeable Kira who was riding on the waves of SEED popularity.

It was all about execution and them failing to understand how vast the landscape had changed between the time of Kamille to the time of Shinn or how organized and rabid the SEED fanbase had grown(Thus making the decision to rush Destiny out to cap on the still burning desires of the SEED fanbase a double edged sword that backfired harshly) that they refused to give Shinn a chance because he wasn't Kira. Just like there are still bitter fans to this day that refuse to acknowledge that Kamille was ever a successor to Amuro's legacy though nowhere near as bitter as the hate they have for the entire ZZ cast and story.
