AHHH I LOVE KEVIN'S WRITING the amount of pain especially in that one scene before Prometheus slaps him always kills me, getting to fight him as Kiana in his regular human form and then the cutscene with MEI and the Flamechaser's heard in the back makes me WEEP they did so well with him I was shocked that they were able to make a villain similar to Otto (in terms of not making him pitiful or too sympathetic but giving us an understanding of them and their goals)
As for my favourite FC, Eden is always my no. 1!! I loved from the moment I laid eyes on her and realizing that she decided to die in that era and the way she spoke about her era ending that day on the stage she stood made me love her more, I also love Pardo, SU and Kosma (and of course Elysia, Fu Hua and Kevin) but Eden always meant the most to me
