a bit overlooked and overshadowed by Warcury's greatness but MARS also has some solid gas in this chapter. Breaking inside the labophase with absolute ease, instilled shock in Jinbe with his overwhelming haki (and ge absolutely had no problem shitting & disrespecting enraged Linlin), and Zoro's surprised "what the hell is that?!" to which Jinbe just say they need to get the hell out of there.
Also on closer look, you can see he is accompanied by sparks of white lightning all around him while flying, which may hint to some of his powers. Mars is underrated, I can absolutey see him in the top 3 elders. Stronger than admirals ofc.
