I wouldn't really like Dixie having the Animal Buddies in her moveset. She's more than capable of doing things on her own and she has enough canon capabilities to fill up a moveset. Plus I think that exploring her ponytail as a means to float in the air, turbine, fifht limb, etc. is both more interesting and more tied to her identity.
On the other hand Crono is the one character for who I think summoning companions would make sense. He's a little bland on his own, and Chrono Trigger's combat system is all about team attacks. But the way I Imagine him probably isn't doable...
That’s fair, I think I’m in the minority in that opinion anyways. I think there’s plenty of moveset space to give Dixie all of her canon abilities while still having room for the buddies as specials. They’d only really take up four total moves of her whole set so she has everything else left over for things like her hair, bubble gum gun, guitar, or anything else.
Here’s a basic moveset idea I thought up for Dixie that I think could be a ton of fun. Of course this isn’t the only way that they could make Dixie work. She could be fun solo or as a transform pairing with Kiddy but this is just the set I’d have the most fun with personally:
Dixie Kong with Animal Buddies
Basic Attributes:
I’m not really an expert on exact stats and percentages so I’ll just say that Dixie is slower and floatier than Diddy. What she lacks in speed, she makes up for in her amazing recovery.
Weak attacks:
Jab - Diddy’s jab combo
Forward Tilt - Dixie performs her signature hair twirl and moves slightly forward.
Up Tilt - Diddy’s up tilt
Down tilt - Dixie performs a sweep across the ground with her hair which can trip opponents.
Dash - Dixie’s hair twirl. Very similar to her forward tilt but continues her momentum for short while.
Smash attacks:
Forward Smash (Bubble Gum Gun) - This is basically a combination of Diddy’s Peanut Gun and Mega Man’s buster cannon. The animation is very similar to Diddy’s but the attack only travels as far as Mega Man’s. If she charges too long, the gum blows up in her face like Diddy’s Peanut Gun.
Up Smash - Diddy’s up smash
Down Smash - Dixie strums her electric guitar sending shockwaves around her which slightly stuns opponents before sending them flying. The shockwave is relatively short range (maybe 1.5x the range of Mewtwo’s neutral aerial) and functions a lot like ZSS’s blaster for the stun.
Grab:
Dixie has a fairly unique grab that functions very similarly to Donkey Kong’s. She grabs the opponent with her hair and carries them over her head. Like DK, she can walk around with them for a bit before tossing them in the chosen direction.
Specials:
Neutral Special (Rambi)- Dixie hops on top of Rambi. The move functions very similarly to Jigglypuff’s roll where Rambi charges up in place before dashing across the screen. Dixie jumps off as soon as the attack is finished.
Forward Special (Squitter): This is the only buddy that Dixie can move around freely while riding it. While riding Squitter, Dixie can fire webs in one of three directions, either straight ahead or in a 45 degree angle up or down depending on the direction held.
Up Special (Squawks): Squawks lifts Dixie and flies upward about the height of Pit’s Brawl special. While flying, Dixie can press neutral special to fire coconuts from Squawks’s mouth.
Down Special (Enguarde): Dixie hops on top of Enguarde and summons a big wave which carries them across and Enguarde jabs anyone in the way with its sword. This attack travels a much shorter distance than Rambi but has a good amount more height and no charge up time.
Aerial Attacks:
Neutral Air - Diddy’s neutral air
Forward Air - Dixie’s signature hair twirl. After performing the attack, you can hold the attack button to glide in a slightly downward trajectory like in her games.
Up Air - Diddy’s up air
Down Air - Diddy’s down air
For Dixie’s second jump, she performs a twirl with her hair that lifts her upwards, which is taken from her ability from Tropicsl Freeze.
Final Smash:
Dixie takes out her guitar and performs her stage victory theme sending huge shockwaves across the screen. This is a lot like Donkey Kong’s Final Smash from Brawl.
