Dangit! I did a bunch (combinations for all five of the characters I use with themselves and with each other) before going back and noticing the "no doubles" part! Oh, well, I've still got all the non-doubles from those, I'll send 'em. Change what you want, doesn't matter too much to me. You ready for this?
Meta Knight + Ness = Flash Whirlwind
With Ness’ baseball cap and Meta Knight’s mask, Kirby gains a Neutral B of deadly proportions. Kirby whirls around in a tornado that’s basically the same as Meta Knight’s, though it doesn’t last as long, and isn’t as easy to move around. When it ends, the tornado disappears in a bright green flash that blows opponents still caught in it away.
Meta Knight + Ice Climbers = Snowstorm
A parka and a mask makes Kirby look a bit ridiculous, but it gives him a great move to use! He spins around, making a tornado like Meta Knight’s, only he can’t move around. The advantage now is that the tornado is freezing cold, blowing snow and ice around in it. Aside from being more damaging this way, the snow and ice also make the tornado a little bigger.
Meta Knight + Lucario = Aura Tornado
Donning Meta Knight’s mask and Lucario’s ears, Kirby gain the Aura Tornado ability. After charging up like Lucario does for his Neutral B, Kirby can shoot forward not an Aura Sphere, but the Aura Tornado. It launches forward, looking like a blue version of Meta Knight’s tornado, catching and damaging opponents it hits. Charging up makes the tornado go further forward before disappearing.
Meta Knight + Toon Link = Wind Arrow
Meta Knight’s mask and Toon Link’s green hat cause Kirby to pull out a bow when using his Neutral B. He pulls it back just like Toon Link, and fires an arrow the same way. If the arrow comes in contact with someone, a rush of wind shoots out of it and blows the enemy away, greatly helping the knockback of the arrow.
Ness + Ice Climbers = PK Freeze II
What’s this? With Ness’ cap and the Ice Climbers’ parka, Kirby gets PK Freeze?! Well, sort of. This acts like Ness’ PK Flash at first, except that the glowing energy is now light blue instead of green. When the PK Flash is released, though, the explosion is accompanied by a blizzard of icy particles. Because of this, the flash shoots out icy chunks in every direction that travel a short distance before disappearing.
Ness + Lucario = Pure Energy
Lucario’s ears can be seen sticking up underneath Ness’ baseball cap, but Kirby doesn’t seem to have a problem balancing. With this attack, he’ll charge up like he’s using Lucario’s Aura Sphere (though he looks like Ness’ during PK Flash while charging). Once you charge this attack, you can release it with a second press of the B button. When you do, Kirby will explode in a violent burst of green and blue energy! This is a powerful attack with a huge hitbox, but it’s very slow.
Ness + Toon Link = Flash Shot
Toon Link’s cap takes on the colors of Ness’ cap, granting Kirby a deadly projectile. Pulling out a bow, Kirby readies it with an arrow made of green energy. After charging, Kirby fires the arrow, and after it travels a set distance, it disappears! A moment later, it explodes like a PK Flash! If it hits anyone beforehand, they won’t get hit. Because of the range of this normally-devastating blast, it’s no longer as powerful when used like this.
Ice Climbers + Lucario = Ice Sphere
A parka and ears. Kirby, are you an ****** or their pet dog? For this attack, Kirby charges up an Aura Sphere, though it’s a much lighter shade of blue. It launches forward the same way, too, but on contact, there’s a good chance it’ll freeze opponents!
Ice Climbers + Toon Link = Ice Arrow
Did you expect anything else? With a parka in the green shade of the Hero, Kirby pulls out Toon Link’s bow and fires an arrow with a glowing blue tip. When it strikes an opponent, it does no knockback at all, but it does freeze them! Use it to follow up with another attack!
Lucario + Toon Link = Aura Arrow
Toon Link’s green cap sits between a pair of Lucario ears atop Kirby’s head. Charge this up like an Aura Sphere, and release it the same way. When you do, it takes the shape of an arrow, rather than a ball. This, unfortunately, doesn’t boost the attack much. It’s a little bit stronger, but not too much.
