Notes:

I made this and the accompanying pic probably 3-4 months ago? Egh.
I made this and meant to upload immediately but left the job unfinished…
…just like my playthrough of Bastion…

The Kid from Bastion makes almost too much sense to me for a Smash character. He has a plethora of melee and ranged weapons he could swap between (many being their own moves) with incredibly different uses: the War Machete for rapid strikes, Cael Hammer for power & launch, Brusher's Pike for reach (throwable); Fang Repeater for rapid ranged damage, Breaker's Bow for sniping, Scrap Musket for close-range interrupt, Dueling Pistols for mid burst, Army Carbine for slow charging snipe nukes, Flame Bellows for… fire, Galleon Mortar for skilled range AoE, and the Calamity Cannon for EXPLOSIONS. As for a final smash, the Battering Ram with its special Colossal Smash that causes fiery projectiles to fall from above in an AoE would work (it's also the only two-handed wep, and appears only in the final stage).

Also, the Bastion world fits perfectly for stages seeing as the maps there are floating masses of land that procedurally fall into place as you approach the edge as long as the path continues. Lots of smashable bits and stage hazards, too. This makes for a perfect Smash stage. The Bastion itself could make a good "Omega" stage as well, I reckon. For stage music, well, Bastion's soundtrack is goddamn beautiful. Can't go wrong.
