Spirit Battle ideas

[TreeChopperVillager]

Since I can't find my old post on here, i'll make a new one. Here's one more.

Spirit: Diamond Armor Steve ( Minecraft )
Type: Ace, Attack, Primary
Effect: Majorly Increased Sword Damage

Opponent: Link x2
Stage: Xenoblade Chronicles Omega.
Music: Bein' Friends.
Conditions: Opponent is hard to make flinch or launch.

 

[BowserKing]

Spirit: Tyrantrum
Spirit Type: Ace Shield
Spirit Effect: Increases smash attack damage
Spirit Battle: Giant (grey skin)
Arena: Guar Plains
Rules: Stamina Battle (has 180 hp)
Bowser is giant
Bowser prefers using Down Special
OST: Battle: Trainer (X/Y version)

Bumping the thread back (it's been weeks since I posted there)

Spirit: Iron Golem
Spirit Type: Ace Neutral
Spirit Effect: Increases defence
Spirit Battle: Giant
Arena: Town and City
Rules: Stamina Battle (has 100 hp)
The enemy has super armor, making it hard to flinch
The Enemy is Giant

[notarandomraider]

Spirit: Jazz Jackrabbit (Advanced)
Opponent: Bunny (Green) (x2)
Spirit Info: Support Grab that gives you Shooting Attack Up

RABBID LUIGI

OPPONENT: Bunny

RULES: The opponent has increased move speed. The enemy can damage you by dashing into you. The enemy heals by dealing damage

STAGE: Mushroomy Kingdom (Battlefield)

MUSIC: The Legendary Air Ride Machine

ORIGIN: The dash and healing is a reference to Rabbid Luigi's "Vamp Dash" move. The stage chosen is based on Kingdom Battle's 2nd world, and the song choice is an orchestrated piece that sounds similar to Grant Kirkhope's works

 

[SneakyLink]

I made a few spirit battles for characters from TF2, Banjo-Kazooie, and Minecraft. Let me see if I can dig (heh) them up.

I hope you die a particularly painful death

 

[SneakyLink]

Found my TF2 battles:

Got bored so I came up with Spirit battle ideas and skills based on the other classes:
Scout - Ness in Blue alt costume with Home Run Bat Equipped. Primary Attack Spirit that increases Battering Items Damage.
Soldier - Snake in Red alt costume that prefers Side B and Forward Smash. Primary Attack Spirit increasing Foot Attack Damage (think Mantreads).
Pyro - Samus in Blue alt costume with Superspicy Curry permanently active. Primary Attack Spirit that increases Fire Attack Damage.
Demoman - Ganondorf in his Grey alt costume that uses Smash Attacks more often and resists Explosive Damage. Primary Defense Spirit that increases Sword Attack Damage (this one was hard to come up with).
Engineer - Mario in Builder Outfit with an increase in ranged Damage and a Heavy that appears after a while. Primary Defense Spirit that increases Electric Attack Damage.
Medic - Dr. Mario in Blue alt costume with a Heavy teammate. Dr. Mario heals over time and tends to avoid conflict. Support Spirit that gives Critical Immunity.
Sniper - Link in Red alt costume that primary uses neutral B and has increased Damage with Ranged Weaponry. Support Spirit that increases Projectile Damage.
Spy - Invisible Shulk in Blue alt costume that prefers Side B. Also starts with a Poké Ball that always summons Ditto. Support Spirit that Jams an Opponents Final Smash Meter (basically Sapping it)

I chose not to use Heavy for any of the Battles (except as a teammate) simply because he didn't fit any of the ideas I had in mind.

I'm gonna keep looking for the B-K and Minecraft ones.

 

[TheYungLink]

You know what would spice up this thread?

If there was some kind of tool that allowed people to throw together splash images like this of their imagined spirit fights. I don't have good skill in image editing, so it's not like I'm able to offer a solution, but it would certainly make this thread more fun and popular.

Anyway, I'll make my submission now that I've read every post and didn't catch anyone do my idea yet:

---

Pokémon Trainer Red

Legendary/ Primary/ Attack

Puppet Fighters: Pikachu, Giant Squirtle, Giant Ivysaur, Charizard, Ice Climbers, King K. Rool

Conditions
Defeat an army of fighters
Reinforcements will appear after an enemy is KO'd
Strong winds are blowing
The fighter will suddenly have a Final Smash
Only certain Pokémon will emerge from Poké Balls (Eevee)

Stage: Summit Battlefield form

Other notes:
Characters are fought one at a time, so this won't be as daunting as the Geno fight.
Only Poké Balls spawn.
Unlike other spirit fights with their Pokémon, this time the Pokémon Trainer is present in the background as long as Squirtle, Ivysaur, and Charizard are out.
Venosaur, Blastoise, Lapras, and Snorlax are represented through their existing spirits, like how the Champions in Zelda (Breath of the Wild)'s spirit fight uses the spirits of Revali, Daruk, Mipha, and Urbosa that were already in the game. However, King K. Rool is not giant this time, due to Red's Snorlax and not the one blocking your path, and as such actively attacks you.
