It's been a while since I've watch a Gundam series that kept me interested. Build fighters had a very interested concept and I felt a lot of nostalgia, especially after seeing the YMS-15 Gyan.
This was my go to suit in Federation v.s Zeon, by the way does anyone remember that game?
Anyway in my opinion Iron Blooded Orphans is one of the most refreshing Gundam series since Gundam 00. The combat scenes are creative, the characters have a lot of depth and so far no one is incredibly over powered. The story takes place 300 years after a conflict known as the "Calamity War". Earth when under a huge government reform, but conflict started building on Mars. Our hero, a boy named Mikazuki Augus, belongs to a private security company called Chryse Guard Security (CGS). The company accepts a mission to escort Kudelia Aina Bernstein, a girl who seeks to liberate the Martian city of Chryse from the rule of one of Earth's major powers. So in contrast to 00 which had a lot of drama between military groups, Orphans has a lot of focus of corporate greed. However, the military organization Gjallarhorn attacks CGS in order to nip this rebellion in the bud. CGS begins an evacuation, using Mikazuki and the other children as decoys. Orga Itsuka, the leader of the boys, decides to take this opportunity to rise up in revolt and launch a coup d'état against the adults who have been oppressing them. He gives Mikazuki the task of repulsing Gjallarhorn, and Mikazuki enters battle using the Gundam Barbatos, a mobile suit from the Calamity War era which has been serving as CGS's power.
