Or maybe setting parts of the stage on fire temporarily?
I like the idea of the slow-moving projectiles, but at the same time, I worry because...
1. They're easily deflected, absorbed, etc., giving him extremely unfavorable matchups against characters like Ness, the villager, etc.
2. The projectile needs to either apply pressure or at least balance the pressure placed upon him by opponents.
If Bowser is going to stand a chance, he needs something that could reliably control the stage (ground fire) or the projectile needs to be quick enough that an opponent who runs to other end of final destination and spams projectiles at him will have to deal with his projectiles in turn.
He's too big a target to not have some form of counter-pressure, unless they give him a GODLY approach mechanism this game (like MK's tornado).
Good points. I, largely, want to bring Smash more towards accurate representation of the characters whenever possible, so that was my priority. Igniting the stage, however, is completely awesome...
Maybe when using the fireballs in the air they angle downward and when they collide with the stage they heat up a spot and make it glow red to cause damage?
Same with using his sustained fire breath, he could heat up the area in front of him and you could watch the stage glow red and start to dim over time.
I personally would solve the pressure issue by putting in this move that I've posted elsewhere (five minutes ago):
Koopa Claw replacement:
CHOMP TOSS
While the button's held, Bowser swings a chain chomp around by its chain above his head, hurting aerial attackers. When the button's released, he throws the chain chomp forward which bounces along the ground trying to bite enemies for a few seconds before leaping down off the stage.
-He'd be able to walk slowly while swinging it.
-The roaming chain chomp would turn around when hitting a wall.
-The chomp can be knocked away by attacks.
-The chomp, when connecting with an enemy, bites down on them and chews for a second, temporarily slowing the enemy and hurting them.
-Only one chomp can be on the screen at a time, so the move isn't spammable.
I would love playing as Bowser if his shtick changed more towards controlling the stage and forcing enemies into his powerful blows.
So, with the fireballs occupying the air space and the chain chomp patrolling the ground, he could hold a significant advantage in controlling where enemies can safely patrol.
As far as reflectability of the fireballs... yeah. It's a big downside.
He fortunately would be able to at least cancel reflected projectiles with another fireball to clash against it.
