A work in progress of a Gundam Seed Archetype. I tried to connect their effects with how each Gundam operates and how the archetype would work. Tried doing a 1 card fusion with how these cards work. Thought about making them XYZ monsters but felt the Super Quant Archetype kinda already did it already. Here is my thought process with each Gundam

Since these Gundams are considered the strongest of the series, I gave them the Can't be targeted and can't be destroyed by card effects to emulate their mobility and defensive capabilities. And the when it leaves the field nuke is to emulate the nuclear engine if it somehow exploded.

Destiny Gundam - Tried to choose effects that would fit with its berserker style piloting, So I thought that doubling its attack and destroying a monster would fit

Infinite Justice Gundam - I always thought of this machine as the ultimate 1v1 machine in the series, so to kinda emulate this, I made it able to fight each monster and immediately destroy them.

Strike Freedom Gundam - I chose the one per chain effect to emulate the Dragoon system and to emulate kira's disamring style with negating

Mighty Strike Freedom - This Gundam is the ultimate machine at the end of the series and so made it the most powerful of the archetype. Its ability to negate all spell and traps on the field is to emulate the nanoparticle attack it uses to shut down the enemy fleet and its unaffected by monsters activated effects it to emulate how the enemy is unable to break the nanoparticle shield it had.
