Not to mention, Luffy does have decent heat resistance which should reduce the effectiveness of Johnny’s Power Poots.
How good is his heat resistance?
He will also have to deal with Luffy’s Accelerated Development which will allows him to grow stronger and faster as the battle continues.
This shit is gonna be so annoying to deal with.
Teleporting Spam will be annoying but he has some experience with Enel, who does a similar thing with his speed and precognition
Johnny's teleportation helps him teleport great distances.
He can teleport as far as space. This will make Johnny particularly annoying to deal with because Johnny can teleport as far as he needs to avoid Luffy, which can negate Luffy's AP/Precog/IA for the time being.
With Luffy’s LS, if he grabs hold of Johnny, Johnny is not escaping. And if Luffy picks up on movements that Johnny always do to teleport (the raise his hands up and down iirc), he will definitely find a way to restrain him.
The thing is that this is no easy task.
For the first part of just trying to restrain Johnny, not only can the kid teleport,
he's shown to be very elusive without Teleportation. Of course, those lasers were standing still, but I can argue that Johnny has very good aerial movement which will make it hard for Luffy to grab and restrain.
Even then, Johnny can just use his Shape Shifting powers to turn into a smaller animal to escape Luffy's grasp, so LS isn't as big of a factor as you think.
Now for that second half about Johnny teleporting, it seriously depends on the distance of both competitors.
Johnny in this key is a ranged fighter who doesn't engage in CQC/H2H, so really the only way I can see Luffy catching Johnny is if he closes the distance on him, and even then, Luffy still has to deal with all of the aforementioned things above.
My question is that are Luffy's senses so good that he can avoid city-sized Tornadoes and Explosions?
Sure, Johnny has a very high durability, but Luffy has face off and defeated characters who could no-sold his attacks like Don Krieg
This is fair, but let me go through each Gear Luffy has, including his base.
Base Luffy vs Johnny X: Luffy is basically incapable of harming Johnny. Johnny is far too durable, and he has Toon Force, Elasticity, Regen (albeit inconsistent), and Immense Pain Tolerance stacked on top of that. Really can't see how Luffy would win this.
Gear 2 Luffy vs Johnny X: Both Luffy and Johnny are basically dead even in terms of Attack Potency, but Johnny is still too durable, just to a lesser extent this time as compared to base Luffy.
Gear 3 Luffy vs Johnny X: Now this is when Luffy can really start laying the smackdown on Johnny. Johnny is still more durable, but the gap between his dura and Luffy's Attack Potency is negligible, so now Johnny will really start to actually feel long lasting pain from Luffy's attacks. Johnny will also have to deal with a roughly 2x AP disadvantage, along with a speed disadvantage, which will make it even worse thanks to Luffy's strong senses.
This fight honestly depends on whether or not Johnny is capable of finishing Luffy off before Luffy finishes him off, which is why I'm starting to lean towards Incon.
