Dejavu -- Brawler w/o HK or PP has... afaik only Onslaught, usmash and dair (spike or not) for kill moves (Fsmash and Dsmash if you like lag frames?). But you'll have a heck of a time fishing for these outside of surprise. Shotput has some use for off-stage zoning, I guess, but in my experience fighting Brawler the endlag on Shotput is
severely punishable (just as bad as a whiffed fsmash or dsmash, I reckon). His horizontal recovery is also practically non-existent, and I really don't know how practical Axe Kick is, or even IF it is. At
best, you have Sheik's damage output without bouncing fish. Or needles.
Swordie has uair, bair, fair, fsmash (range! tipper!), platform shark usmash, and the twirly dair gimp of doom. He gets a great zoning tool with Gale Strike, an OoS and ledge-spiking tool with Stone Scabbard, crazy good recovery with Airborne Assault, and a counter. There's also several crazy/silly strings via jab-dtilt-dthrow-uair-bair-bair, and variations therein.
Gunner, I honestly don't know. However, the best gunner tools are almost certainly Grenade and Mine, of which 1111 has neither. You can still surf around with fair if you want, but you'll be hard pressed to actually zone for damage. I guess you can fair poke and stall for time?
