I just love how expressive Genos is when his stoic face drops away. Emotion is just in full force on his face as if he's giving 100% in expressing it like he does everything else because chill is the only thing he can't do XD. Like his smug look when he earned his spot as Saitama's student, his sass at Child Emperor in the OVA, that halarious "What the fuck" face he made when Tastsumaki was call him and the other S Class insults, and of course the happy puppy face at the end of the last episode.
If I can be honest, anon…I think it’s because Genos is very much coming back into himself as a person. /
This is Genos at his introduction. \
Stoic. Calculating. Very much the mechanical combat cyborg he aimed to become for the kind of power needed in his revenge hunt. The most emotion he showed was shock at witnessing great strength, either from monsters or from seeing Saitama’s one punch. If he could cut off any ties to his former life, including his personality prior to the mad cyborg attack, then that’s all the more focus he can put into his pursuit.
Now, here’s the Genos you brought up. ///
Genos missed out on 4 years of growing into himself. The time he’s spent being a pro hero, the time he’s spent with Saitama, living peacefully instead of pushing himself toward a revenge fueled future that would probably cut off short…it’s given him time to kind of recover who he would have been if the mad cyborg had never attacked his home…….
Of course, he can’t change what’s already happened, I’m sure Genos is aware of that. But at least now, the person he had been along with the experiences he’s had up til’ now to change him along the way have like…led to this? New, growing Genos?? And he’s come so far????? And will only continue to progress with time???????????? / / /
TLDR Genos has pretty much done a partial speedrun of the kind of development he should have needed 4 years of just growing up normally for, and there’s still so much room for him to keep going he’s becoming such a great person…………I hope Saitama’s noticed and is proud of him………./ / / / /
Thank you for reminding me of this good expressive borg, anon ;;;;;;; /////
