Guys, the not-flinching bullets might not even flinch Bae, so it might act as a bait for reflectors, I mean, every reflector except Fox's has a lot of cooldown.
Yeah, if Fox manages to reflect something. If not, regular 34 recovery frames before he can act again.
I barely understand these moves. So there's the bullets from her attacks, which don't flinch, but then there's her Standard-B Bullet Arts that DO flinch, right? @_@
Bullet Arts and Bullet Climax; Bullet Arts are the bullets fired after her attacks if you hold the attack button down while Bullet Climax is her neutral Special. Bullet Arts don't do any hit stun, so they're basically combo extenders purely in damage while Bullet Climax does hit stun and functions more like a sustained Falco Blaster or Ryu Shakunetsu with set knockback.
Invisible Bullets I think is referring to her Bullet Arts... That being said, bullets in general are small so... Look, reflecting her Bullet Arts would be like reflecting Fox's Blaster lasers. You're only getting damage from them and it's not really worth it. Reflecting Bullet Climax would be like reflecting Falco's Blaster or pretty much any non-killing projectile which is more worth it since you can cause hit stun and interrupt them. As projectiles, of course they're prone to reflects, but guess what? They're not worthwhile compared to reflecting kill projectiles like Aura Sphere, Charge Shot, Shadow Ball, Phantom Slash, Lloid Rocket, Mega Man's Side Smash, or Villager's Fair and Bair to name a few. People will reflect them because they don't want damage like how people reflect Fox's lasers, but it's not going to kill either character if they don't reflect or get reflected.
Side note: the Pits' Side Specials don't actually reflect; they deflect like perfect shields do which generally won't hit you since it'll get launched in a different angle away.
