DEAR GARDEN!
You all may be wondering, "What's the deal with that Ace and Marco guy and why does Ace hate his guts?" So here is a handy reference guide!
"My" Ace was a pirate in my crew. He started off trying to kill my Pops, but because he protected his friends and sacrificed himself to save them, my Pops liked his style and asked him to join. Ace refused and spent the better part of half of a year still trying to kill him. Eventually he started to realize killing Pops wouldn't get Ace what he wanted and he agreed to join us instead. "My" Ace became one of my best friends even before he joined the crew and his fire logia and mad skills at pirating quickly made him a commander like me. He was not actually a pirate because he's a lawless scoundrel, he was a pirate because he valued freedom, his friends, and despite offers to join the marines as a legalized pirate (shichibukai) he knew they would want him dead if they know the whole story. That is one of the things I valued most about him. He was smart, loyal, brave, and he accepted people for who they really are even if he often thought others wouldn't accept him like that in return.
The Ace you see here insists he's from a different world than mine, even though he looks and primarily acts just like my Ace, he's sick of me explaining it individually (apparently). Without giving away any Ace-secrets; he's still loyal, friendly (to everyone who isn't a pirate apparently), helpful, cheerful, driven, and with his own code of justice. He would rather I gave up on him entirely, but that is something I'll never do because it would be like giving up on my best friend, no matter how much the Ace here would rather just cut my heart out to eat it. That said, I'm not going to force friendship on you Ace Commodore, but neither will I ever give up. If you want my space, I'll attempt to give it. As for why Ace hates me, personally I think you're better off asking him, but really it's just because he's a marine and I have this spiffy tattoo of which he's secretly jealous because all he's got is a justice hat and cap. Is there anything else you'd like me to cover Sparky?
