What this tier list can tell you
Choosing a unit from the wrong version of a tier list can leave you comparing characters that do not match your roster. For Undertale Adventures X, community ranking videos exist, but a verified Legendary-and-Rare ranking cannot be established from their public page details. The comparisons below explain which rankings specifically name X, which placements are documented elsewhere, and what to check before choosing a unit.
The distinction matters because an overall unit ranking does not automatically answer a rarity-specific question. A high placement alone does not establish that a unit belongs to the Legendary or Rare category. It also does not establish whether the ranking covers the same variant or currently obtainable units.
This page therefore separates documented community placements from recommendations that would require additional confirmation. No unit is labeled Legendary or Rare solely because it appears in a high or low tier.
For a practical comparison, you need three pieces of information together: the exact unit identity, its confirmed rarity, and a ranking that applies to Adventures X. If one is missing, treat the placement as a lead to investigate. That approach still lets you use community lists while keeping an incomplete reference from deciding your entire lineup.
Adventures X community ranking videos
Two identifiable YouTube Shorts explicitly concern Adventures X. Their publication dates help distinguish them, but their accessible page text does not reveal the actual tier placements shown in the videos.
| Creator | Published | Identifiable ranking |
|---|---|---|
| Fexia, @Fexia_YT | October 16, 2026 | “Updated TIERLIST v3,” with a related link to an Adventures X obtainable-unit ranking |
| Karez14, @Karez14 | October 13, 2026 | “Undertale Adventures X - Units Teir List,” described by its creator as a personal opinion |
Fexia’s ranking page identifies the video as a third-version update. That establishes how the creator labels the upload; it does not establish that every unit was retested or that the list reflects a particular balance patch. Its related link explicitly mentions obtainable units, which is a useful scope distinction when researching a lineup you can actually assemble.
Karez14’s ranking page presents its ordering as the creator’s own judgment. Personal rankings can help players compare experiences, but that description should not be mistaken for an official classification or a consensus among players.
The two uploads are three days apart. That does not prove the later video corrects the earlier one, and there is no readable placement-by-placement comparison establishing where the creators agree or disagree.
When viewing either video, check its tier chart directly. Record the exact unit variant and any explanation attached to its placement. A video title can establish the game being discussed, but it cannot tell you which Legendary or Rare unit wins a comparison.
Documented community placements and their limits
TierMaker contains two broader Undertale Adventures ranking pages. Neither page title identifies Adventures X, so their applicability to X needs confirmation before their placements become current gameplay recommendations.
| TierMaker page | Community sample | Documented detail |
|---|---|---|
| Undertale Adventures Tier List | Seven submitted lists | Displays an aggregate ranking with visible S and A entries |
| Undertale Adventures Units tierlist 2025 | Seven submitted lists | Reports its latest ranking update as June 28, 2025 |
The general Undertale Adventures page combines community submissions into an aggregate ordering. Seven submissions provide a limited sample of player preferences. The page does not establish a separate Legendary-only or Rare-only ranking.
The 2025 units page reports the same number of submissions, but that does not demonstrate matching voters, matching unit pools, or matching results. Its June 2025 update date also predates the two October 2026 Adventures X videos. The dates alone cannot tell you which units changed strength.
The following selection records placements visible on the general TierMaker page. Readable labels are derived from its image filenames; they are not independently verified in-game display names.
| Readable unit label | Filename identifier | Recorded community tier |
|---|---|---|
| Hotlands Dust | hotlandsdust | S |
| Serious Frisk | friskserious | S |
| Waterfall Dust | waterfalldust | S |
| Alphys | alphys | A |
| Muffet | muffet | A |
| Undyne | undyne | A |
These entries show a distinction between the page’s S and A groups. They do not establish an ordering within each group. For example, the displayed placements support saying that Hotlands Dust and Waterfall Dust occupy S on that community page; they do not establish which is stronger.
Variant names are especially important here. Serious Frisk should not silently become a recommendation for every Frisk unit. Likewise, the two Dust labels should remain separate when checking whether a ranking corresponds to a unit you own.
None of these selected entries has a confirmed Legendary or Rare designation on the ranking page. Assigning those rarities would add information the page does not establish. Their value is as specific references you can check against an Adventures X unit entry, rather than as a completed rarity ranking.
How to compare Legendary and Rare candidates
Start with the unit you are considering and work outward. Searching for a familiar character name first can mix together variants, older lists, and unrelated Undertale rankings. Matching the full unit identity gives you a more useful starting point.
The Undertale Adventures X Wiki provides a Units navigation section alongside Areas, Items, Development Links, and Codes. It describes itself as a fan-maintained encyclopedia that community members can edit. Its homepage is a route into game information, but it does not publish a Legendary-and-Rare tier chart.
Use this checklist when comparing candidates:
- Match the complete unit name. Keep variant words attached to the character name throughout your comparison.
- Verify the rarity separately. Do not infer Legendary or Rare status from an S, A, or lower placement.
- Check that the ranking names Adventures X. A broader Undertale title leaves the game version unresolved.
- Read the ranking’s scope. An obtainable-unit list answers a different question from a list that includes every unit its creator knows.
- Look for the reason behind a placement. A tier letter is more useful when the creator explains the situation in which the unit performs well.
- Record disagreements precisely. Note the exact unit and competing placements instead of assuming two entire lists contradict each other.
If you compare units through your own play, keep the circumstances as similar as possible. Compare the same challenge and change one candidate at a time where practical. Record what improves or worsens rather than deciding from a character’s reputation.
Keep your notes simple: unit name, confirmed rarity, ranking date, creator, and observed result. If two creators disagree, those details help you determine whether they evaluated different variants or used different criteria.
Search-result relevance also matters. The Facebook answer page includes general character debates and avatar discussions, while the TikTok discovery page includes boss edits, friendship rankings, and music lists. Those topics do not establish Adventures X unit performance. A matching search phrase is not enough to make a result useful for choosing your roster.
FAQ
Is there a verified undertale adventures x legendary rare tier list?
A complete, verified rarity-specific ordering is not established by the public references discussed here. The Adventures X videos identify community rankings, but their accessible page details do not disclose the placements needed to build a Legendary-and-Rare table. The TierMaker pages show broader rankings without confirming those rarity assignments.
Which Legendary unit is the best?
No defensible Legendary winner can be named from these ranking records. Choosing one would require confirming both the unit’s rarity and its placement in an applicable Adventures X ranking. The documented S-tier entries alone do not meet those requirements.
Which Rare unit should I choose?
First confirm which candidates are actually Rare, then compare rankings or observations for those exact units. A character appearing in a general community list does not establish its rarity. Use the comparison checklist above to narrow the decision without relying on an unsupported label.
Does S tier mean Legendary rarity?
No. On the TierMaker page, S is a community ranking position. Legendary would be a rarity classification, and that classification is not established by the S label. Keep those two fields separate when recording a unit’s details.
Are the October 2026 videos more relevant than the 2025 list?
They are more directly relevant by title because they explicitly identify Adventures X, and their publication dates are later. That makes them sensible references to inspect first. It does not independently verify their conclusions or prove that every placement applies to your circumstances.
Can the community rankings be compared directly?
Only after matching their game scope, unit variants, and ranking criteria. The two TierMaker pages each report seven submissions, but equal sample sizes do not establish agreement. Likewise, the two YouTube upload dates do not reveal whether their creators assigned the same units to different tiers.
