General Tips
The 11-54 [STORM] is the fastest flying defender, making it a great option for pursuing and dealing chip damage to the Kaiju. Since it can also fly, you can distract the Kaiju by harassing them with your bullets and flying away just when they are in melee range (note that this may not work on Kaijus that can charge or fly). This makes it an extremely good defender when you need to distract the Kaiju as it can fly away to safety and position itself in advantageous places with little effort.

Good Matchups
The 11-54 [STORM] excels when going against Kaijus with nothing in their arsenal to eliminate it as they usually struggle with killing it. You can also position yourself in places where you can shoot the Kaiju, but the Kaiju can't shoot at you in order to gain an immediate advantage and force them to turn their attention towards you, often struggling to kill you in the process.

Counters
Kaijus that can charge are your hard counters. There's not really any way around it, they are basically put on this Earth to kill you. Your best bet is to just not get their attention unless you want to get yourself killed. You could also put yourself in certain places that conceal your location, but this is map specific.
