Welp, Chopper confirmed for a Spark. Abandon the universe, I guess. In any case:
1) As I said, Chopper confirmed for a Spark. And he and Usopp together are already in full science mode. With Donny potentially helping them. Between them and, later, Franky, with Modern real world technological tips (from Soundbite), not to mention dials... Straw Hats are going to get some very nice equipment.
Speaking of Chopper - human and humane. This logic might be able to counter his madness a bit. Even if it is likely to lead to a compassion limit break at some point. And, really, this is where it's going to end up, isn't it? Solar exaltation is pretty much "human to the max", which is what Chopper's power is all about. In any case, he has become one of the heavy hitters with this, and how this develops is going to hold my interest for sure. There's lots of potential there.
And speaking of weapons - I'm guessing we already know weapons of dugong squad, but Carue's... A lance rack to stab people with maybe? Duck cavalry for the win! I mean, I did notice him discussing it with Usopp.
2) So... Lassoo. Have you heard of
Theseus' Paradox? Because this seems helluva relevant here. What with Usopp and Chopper making upgrades. Speaking of, I do wonder how adding new features would impact the biological form of Lassoo. Like, if they simply slap some sights on the gun form, would Lassoo get better vision? Or is welding needed? I mean, the manual didn't seem to translate into Lassoo's biology in any noticeable way (well, it might have given him knowledge of his own design, in which case Chopper's notes should give him a lot of insight in general), so the question of "at what point does something become a part of his body" is quite relevant. As is "at what point does something stop being his body". Because this way lies cloning. Replace parts of him piece by piece (as long as he maintains his personality throughout), assemble a second gun from replaced parts - do you have two Lassoos now?
Or if you take the trigger mechanism and put it into Franky's cannon arm - would that arm get an ability to transform into a dog? Lots of
SCIENCE! to be done here.
3) Huh, so Soundbite is already at "cook meat with sound" stage? That's a fast progression, that it is. And it should work even better in water, meaning that fishing really shouldn't be a problem. Speaking of water, Cross really needs a submarine. Soundbite would work great as a sonar, and it adds a lot of tactical possibilities.
So, onto people listening in...
1) I kinda wonder what Whitebeard's reaction is. I mean, Cross did call him.
2) On the subject of Impel down - you are assuming that all sentences are for life there. That... is a big assumption, if perhaps warranted. Just wanted to make sure there.
Still, Cross is definitely getting a bounty, and probably lots of contacts in the rebellion (because they'd want to use him for sure) and other factions. I wonder how soon he'll start getting mail with request to read certain things aloud. Hey, ads would sell for a lot on SBS.
