This is my favorite boss fight in the game! At first I thought it was just gonna be “He’s the obvious bad guy in disguise” but it turns out he was the original user of the Gravity Circuit! I loved how it parallels Omega from MMZ3 but instead he’s a good guy just making sure the new user, kai, can handle it.
Everyone is pointing out how Nega reminds them of Omega and Zero, but nobody mentions the obvious Proto Man vibes he has. Everything about him being the original model that was forgotten, the contrast between the old and the new, their themes of hope and regret... He mentors the one to replace him. And while he's broken and tired, he still cares about the future. Even if that means to be left behind. I mean, just look at those sunglasses!
This game had done well recreating the megaman moments, the whole sequence reminds me heavily of Zero, starting from Nega removing his cape (Z2 opening), the battle for true successor of Gravity circuit (Z3 omega) to the heroic energetic boss theme (X2 vs zero). Both of them even have Zero's shoulder armor.
I notice that aside from Last Resort, he only uses the starting four Burst Skills, Flying Strike, Rising Upper and Heavenly Piledrive most of the time, and Catch Interrupt if you mess around too much. You could absolutely make a Nega build.
He probably planned from the beginning to become the commander circuit, instead of trying to take back Kai's Circuit, he just tries to pass on the torch by teaching his abbilities to Kai and making sure that Kai is a worthy successor, now nega can finally rest from the battles living in the underground with the others circuits
