This battle is a symptom of most the character flaws Mc has. He was half assed, arrogant, noble and stupid. He wanted to "test" himself although he knew of Luffys canon arsenal and strength. Instead he just let himself get hit like an idiot without utilizing any magic beyond barriers. WTF does he even have that fruit if he doesn't use magic? And what is the point of parting ways with half of the crew? He will still be handheld and his growth will grow stagnant while at the same time his "captain" is whoring herself out and the others couldn't care less. Only the doctor has a legitimate reason to part ways with the Mc. And what's the point of joining the crew with his waifu constantly watching over his shoulders? He won't go the harem route but still goes the harem route only for him to cockblock himself and so on. This Mc is like a tamer and polite version of issei with 0 resolve, dignity and backbone. He wanted an adventure only to make himself the sidecharacter. He went from wanting a harem to only wanting 1 girl who he can never fully have to still wanting a harem only to make himself a pitiful excuse of a slave owner whose only "slave" who sleeps with him uses him as a sextoy in a new environment where he lost face and is seen like a looser. He has no initiative and can't think for himself. He's honestly just a disappointment from a readers perspective because you constantly root for him to finally make himself stand out or gain a goal beyond the "one piece" only to find out that he's just an Otaku who couldn't measure up to his own dreams.
Mc has no named attacks, I, as a reader, would like some to appear soon. If you are having some trouble here are some suggestions of names: Ruler Themed: Kaiser's Beatdown Maximum Devastation Requiem of Pain Mark of the King USA themed: Freedom Lariat Stars and Strips Grid Lincoln (link) of Greed Uncle S's Elite Heeeere's Tom! (Nuke drop) Demolisher themed: Meat Tenderizer Nut Cracker Bones Grinder Juggernaught's Run Over Use your imagination.
