Firstly, to even see and get the achievements you'll need both the character and the codex workshop item:

• Character
  
• Codex

You will also need to install the following to complete some of the listed achievements. You do not need to keep these installed after you succeed:

• Animosity
  
• Comedian
  
• Royalty

You do not need to be in a multiplayer match to get achievements. A singleplayer match with infinite resources turned on is recommended for ease of completion.

The list is organized by rank (difficulty as per the color of the achievement) and alphabetical order.

Cut the opponent in half twice in a row.

To get this achievement you will need to utilize Chara's preloading ability. You will need to have a save point active to use the preloading ability.

First, use Perception to access Sunderance (you will need to have at least six levels to see this), then press the preload toggle next to the DI wheel before selecting Sunderance.

Let your move play out. Afterwards, use Perception and toggle both your preloaded Sunderance and the ability Sunderance. This will cause Chara to use Sunderance twice, thereby completing the achievement.

( You'll only be able to see the preloaded Sunderance after you've selected the base ability Sunderance. )

Land FOUND YOU round start.

Start a singeplayer match against Robot, use the default ruleset, force him to use CONCUSSIVE BLAST and queue FOUND YOU. If done correctly you'll get the achievement.

---

Return from the jaws of defeat.

To get this achievement you'll need to revive yourself as Chara. This can be done in one of two ways:

1. Have a [SOUL SAVE] point active prior to dying.
   
2. Be level 19 (with the XP bar full), and have a full DETERMINATION bar prior to your death.

Kill yourself with the opponent in any way you see fit, make sure you keep your XP bar full if you're using the second method. You'll only see the revival cutscene by using the second method.

---

Show the opponent your REAL Attack

Use the LV20 ability once your level is 19 then use A REAL ATTACK.

---

Win a match without getting hit

This one's mostly self-explanatory. Start a singleplayer match against any opponent of your choosing, kill them without queuing any moves that could hurt Chara.

---

Have four buffs active at once.

Use [ITEM] four times, eat all of your consumables, if done quickly you'll get the achievement.

---

Relax and watch your soldiers.

To get this you'll need to use LV20 then [ONE'S SUPREME SHADOW]. After the ability is active [ACT] (any way, doesn't matter) and relax.

---

This achievement is painfully easy, refer to the instructions below for: SPARE (Rank 2, Item 2) to complete.

Land a FIGHT Fissure

Firstly, use [FIGHT], then enter into Perception and use Fissure (vertical or horizontal whatever hits). Fissure needs to hit your opponent at the same time as [FIGHT] for you to get the achievement.

---

Supress [sic] your violent urge

To get this achievement you'll need to use [MERCY].

Firstly, make sure that your selected opponent has a basic Hustle move, any of the vanilla characters (Ninja, Cowboy, Robot, Wizard, Mutant) will do fine for this task.

Activate [MERCY], wait a few turns for Chara to speak, then Hustle as the opponent. If done correctly Chara should teleport behind them and tear their heart out. This heart can be controlled by the opponent's DI wheel. To get the achievement, simply guide the opponent's heart back into their body without destroying it.

---

Win a match without getting hit and killing while perfect dodge is active.

This one is somewhat difficult if you're not accustomed to Chara's Evade mechanics.

To get a perfect dodge while using Evade one must predict:

• Height (high or low, just like blocking)
  
• Timing (just like parry frames)
  
• Position

If you can correctly predict what the enemy'll do, you can quite easily get a perfect dodge. Robot is good for this task as KEY PUNCH is convenient to plan around. You'll know when you get a perfect dodge as time itself will slow down to accommodate your next few turns.

Simply lower the opponent's health substantially, make sure you'll be able to kill them in one or two quick moves, then move them close enough to Chara and use any move can be easily evaded. Evade, ensure time is slowed, then kill them.

---

Deny an opponent of their fun.

( Solution discovered by HokkiYoki, profile link in Post-OP, thanks! )

To get the achievement, preform the following:

1. Enter into a singeplayer match with the following settings turned on: Infinite resources, one-hit-KO.
   
2. Set P1 as Chara, P2 as Royalty.
   
3. Use [MERCY] as Chara, wait a few turns, use Tea Time as P2. (This should rip P2's soul out if preformed correctly)
   
4. Use LV20, then preform A REAL ATTACK on your opponent.

Encounter a Royalty

This one's simple. Just load into a singleplayer match where P1 is Chara and P2 is Asgore/Toriel Dremurr (Royalty).

---

Defeat Animosity

Start a singleplayer match where P1 is Chara (The True Animosity), and P2 is Animosity (lesser). You should have acquired the necessary mods in the Preface section. Kill Animosity as Chara.

---

Reach LV20

If you're following this guide to the letter you'll have already gotten this achievement. It's very simple, get into a singleplayer match with infinite resources turned on and use the move LV20- that is all.

---

Use an Item in the middle of a combo

You should by now know how to start, carry out, and end a combo. Use hard-hitting moves with lengthy stun then eat an item.

---

Kill the Comedian(Bonehead,Comedian)

Load into a match where P1 is Chara and P2 is Comedian, Comedian has a unique health mechanic. Hitting him reduces his ability to "dodge". Hit him until he reaches his last charge, then he'll die upon one last attack.

---

Indulge yourself for a moment.

Load into a match, use [ACT] with Indulgence selected, wait until Chara takes a bite of their chocolate bar. You should then get the achievement.

Secret ~

Supposedly by difficulty rating this is the hardest achievement to get as Chara, due to its secretive nature I'll spoiler the instructions on getting it.

It's rather simple, use [MERCY] and spare the enemy, then follow the instructions for Stronger than You(.) If done correctly you'll kill a enemy that you already previously spared without getting hit (and whilst having perfect dodge active). Singleplayer highly recommended for this one (as with the rest of the guide).

Could not have made the guide without the community's help, here are some notable people:

• Eminence : Made the character.
  
• C.C : (Made the thumbnail for the mod itself which I also use here. It is not mine.)
  
• HokkiYoki : Figured out the solution to "Who said you could have FUN?"
  
• gamehanter : Helping with achievements.
  
• Callisto : Massive help with a few of the harder achievements.

A majority of this guide's contents were written in August of 2025. By the time of reading it may be outdated.

If the author of the mod asks me to take down the thumbnail art I will, if they request to be added as a contributor I'll also comply.
