Dude stop that headcannon of saying characteres were got off guard. Bounties are being inflated. Only bounty inflation we know is Buggy and MAYBE child Robin.
The comparison with Usopp is not ridiculous and makes a lot of sense because we are not talking about Coby's pirate bounty but the one giving by a pirate and Usopp was also giving by a pirate. Coby's bounty is not about his strength but his special position as Hero which puts him above others of the same rank and probably from ranks above. So if anything Coby's bounty at Cross Guild is highly inflated. Others of the same rank of him only worths one star.
I give you proper definitions. Are you gonna say they aren't definitions now? Thing is you want to force one of the definitions that you chose that would make you right and me wrong when I'm saying since beginning the definition I'm refeering while talking about engage.
Her first attack wasn't aiming him speciffically but all marines. One escaping doesn't mean her attack failled. She could made everybody into stone. One marine and probably only one Seraphim escaped. Still a succesfull attack. Imagine USA back at 40's saying bombs dropped in Japan wasn't succesfull because one or two japanese weren't killed...
Your headcannon says her perfume attacks are her strongest. There is no enough information of Hancock to support that. Kaido is using his Thunder Bagua against fodder Luffy that was one-shotted. Using the strongest move against someone doesn't mean a shit. Remember the crew complaining about Luffy using Elephant Gun against Franky Chopper(at time the strongest move he had showed to us and them).
Sneak attack is getting someone offguard, by surprise. Not from a blind spot lol.
There is no sneak attack against someone with CoO and even less Future Sight. Also this is war. Everyone is prepared for anything coming from anywhere.
Great! You just proved that characters walks between panels.
Still Coby was clearly shown as the last man behind when threatning Hancock and Seraphims were clearly ordered to be on frontline.
Yes after everything that happened. Not before.
After Teach got his hands negating Hancock's powers Coby finally got the frontline. Great for him.
If you don't have notion of space you should go see a doctor for your eyes. Helmeppo is clearly in front of Coby. Him blocking a mere arrow(probably with haki of course) was suppose to mean anything? If all marines are fighting but he can be this calm talking that means he is not so ahead of the battlefield as the others.
Coby had to get closer to order Seraphim to stop since they were ordered to be on Frontline.
