putting aside PIS electro has the fight pretty easy and he wouldnt lose in comics against spiderman if it wasnt for writer protection. any attempt for Gambit to get close would result in immediate death via invisible electrocution field..
The only hope Gambit has is if he goes full horseman mode..
with prep i'm not sure what Gambit would do with it other than bring his rubber insulation suit which i'm pretty sure it's what he wears anyways..
hmm.. Gambit could put the boot to Electro i guess if he was out of character and blew up buildings to use it agains him.. but, i dont see gambit doing that very often unless he had absolutely no choice..
Gambit is being low balled yet again. The OP stated a few things. First the location takes place in Hell's Kitchen which has tons and tons of places the Rajun Cajun can launch an attack from undetected and let's not forget he was raised by thieves to be stealthy enough to pull it off. Secondly all he needs to do to win this fight is KO Electro which I have no doubt he can do especially after being given three days worth of preparation for this fight. That'd be more than enough time for him to set a trap that an unsuspecting Electro would walk into. I'm actually willing to bet Remy could KO him without charging anything by making use of his agility, speed and reflexes to get passed Electro undetected and bop him upside the head with his bo staff.
