Just because I
really like the idea of the Helper System, I'll go into a bit of detail on how I'd personally like it to work.
General Information
As one of Bandana Dee's gimmicks, he'd have the ability to spawn Helpers from Kirby Super Star. He would spawn these using his Neutral B, with the selection going through similar to the Monado Arts. All Helpers have health, and will stay out until defeated. After being defeated, the helper that was defeated can no longer be spawned in until Bandana Dee loses a stock, or after all the different Helpers have been used. They act on their own similar to those in Super Star, but will generally stick near Bandana Dee and only attack when necessary. However, they're still a bit dumb, so they'll end up running in at bad times. If Bandana Dee is being hurt, they'll come to his aid and try to help. All of the Helpers only have a couple attacks, and do
NOT have recovery moves. They do have mid-air jumps, though, which will help them recover if knocked off. They won't be stuck in tumble forever like Luma is, so there's no need to worry about them dying incredibly early.
Anyways, onto the different helpers!
Waddle Doo
An obvious choice as a Helper, Waddle Doo is the first in line. He has decent health, able to take 40% before biting the dust. He has three different attacks. The first attack is his standard attack, the Beam Whip. A line of energy shoots out of him, going from a 45 degree angle above him to the same area below him. This move leaves him open to be counter-attacked if missed, but covers a wide range to attack both aerial and grounded goes. It does 8% damage.
His second attack is his mid-air attack, the Beam Blast. This move is Waddle Doo's main attack he uses while airborne, where he shoots many small energy bolts diagonally downwards, and keeps himself in the air a bit longer. Similar to the Beam Whip, if this attack misses, he can easily be punished. If all hits connect, the move does a total of 13%.
His third and final attack is Wave Beam. After fully charging the move, he can unleash a large, fast, and powerful energy blast that travels through enemies while damaging them (ie: Thoron without multi-hit properties). If he is successful in landing this attack, it deals a total of 20% damage. However, this attack is
HIGHLY punishable if missed, and can usually result in him taking massive damage. He's probably going to need time to charge this move, too, so you'll have to help him.

Will edit this post with more Helper details in a bit!
