In the rapidly evolving world of Roblox tower defense, securing the most powerful characters is the only way to dominate the leaderboards. The latest updates have introduced a variety of anime reversal secret units that offer unparalleled damage, unique crowd control mechanics, and complex evolution paths. Unlike standard banner pulls, these secret units often require players to complete intricate multi-stage quests, hunt for rare NPC spawns, or grind high-difficulty Legend Stages with low drop rates.
Whether you are aiming to add the devastating Hu Tao (Funeral Parlor) to your roster or trying to track down the elusive Red Hair (Shanks) NPC, understanding the specific requirements for these anime reversal secret units is essential. This guide provides a deep dive into the 2026 meta, covering every secret unit currently available, their evolution requirements, and the best traits to roll for maximum efficiency. Follow these steps to transform your team from a standard lineup into a powerhouse capable of clearing the toughest Nightmare portals.
The Queen of Update 2.5: Hu Tao (Funeral Parlor)
The Update 2.5 expansion introduced one of the most mechanically unique anime reversal secret units: Hu Tao. Known in-game as the Funeral Parlor unit, she is a hybrid powerhouse that utilizes a "Health Meter" mechanic to trade her own HP for massive damage boosts.
How to Obtain Hu Tao
Unlike many other units, Hu Tao is obtained through a series of interactions with her NPC, who spawns in the lobby every 15 minutes. You must complete three distinct quest phases to unlock her base form:
- Phase 1: Defeat 2,000 enemies in any stage.
- Phase 2: Defeat 10 bosses (Portals are the most efficient way to farm these).
- Phase 3: Collect 20 Butterflies (Rare drops found during gameplay).
Evolution: Hu Tao Funeral Parlor
Once you have the base unit, the grind continues to reach her final form. You will need to interact with her NPC again to receive the evolution quest.
| Requirement | Quantity/Task |
|---|---|
| Takedowns | 3,000 Total |
| Passive Triggers | Trigger her passive 50 times |
| Evolution Item | Funeral Hat |
| Special Weapon | Staff of Homa (Homi) |
⚠️ Warning: Hu Tao consumes 10% of her health meter with every attack. When her meter reaches 0%, she is stunned for 6 seconds while she regenerates. Positioning her near a healer or a support unit like Kafka is highly recommended to mitigate this downtime.
The DPS King: Red Hair (Shanks)
Red Hair, based on the legendary Shanks, remains one of the most sought-after anime reversal secret units due to his massive AoE (Area of Effect) and map-wide stun capabilities. He is a multi-step evolution unit that requires both luck in the banner and patience in the lobby.
Finding the Red Hair NPC
To evolve Shanks to his final form, you must find the "Red Hair NPC" who spawns randomly in the server every 1 hour and stays for only 5 minutes. You can check his status by talking to the Traveler NPC in the lobby. The Traveler will give you specific hints based on the NPC's proximity:
- "I did not see that strong red hair guy": Far from spawning.
- "I have not seen that strong red hair guy in a long time": Getting closer.
- "I just saw that strong red hair guy a moment ago": Recently despawned.
- "I recently found that strong red hair guy": He is currently in your server!
Evolution Path for Red Hair
Shanks has a double evolution path. The first requires basic materials, while the second requires the Haki Hat.
| Evolution Tier | Required Items | Cost |
|---|---|---|
| Tier 1 | Griffith Sword, 50 Metal, 5 Gold | 5,000 Coins |
| Tier 2 | Haki Hat (From NPC), Straw Hat | 10,000 Gems, 10 Rolls |
Legend Stage Secrets: Igorus and Amami
For players who prefer grinding stages over chasing lobby NPCs, the Legend Stages offer two powerful anime reversal secret units. Both Igorus (Igris) and Amami (Rem) have a 1% drop rate on Nightmare difficulty.
Igorus (The Shadow Monarch)
Igorus is a boss-killing specialist. His passive, "Shadow Monarch's Power," grants a 30% damage boost if a Sun Assassin unit is present on the field. Furthermore, his "Boss Slayer" trait allows him to deal 40% more damage specifically to boss-type enemies.
Amami (The Executioner)
Amami is considered a "must-run" for high-wave infinite runs and leaderboard pushes. Her primary utility comes from her "Continuity" passive, which allows her to instantly defeat any enemy that falls below 10% HP. While 10% may seem low, in late-game scenarios where enemies have billions of health, this execute mechanic saves minutes of clear time.
💡 Tip: To farm these units efficiently, use a macro on the Nightmare Legend stages. Igorus is particularly easy to solo if you have at least one high-level DPS unit like Shanks or Sukuna.
Banner Secrets: Kyito and Event Units
While most secrets are quest-based, some reside within the banner or limited-time events. Kyito (Kirito) is a prime example of a banner secret that requires a massive investment of gems.
Kyito Evolution
Kyito is a scaling unit, meaning he gets stronger the longer the match lasts. His "Dual Sword" evolution requires 5 Goblin Heads, which are exclusively dropped from the Igorus Raid.
- Stacking Speed: Each attack increases his attack speed by 0.01%, stacking up to 30%.
- Critical Focus: When Kyito lands a critical hit, he deals 3x damage. For this reason, the Critical trait is mandatory for Kyito to be viable in the 2026 meta.
Winter Event: Ice Cream
The Ice Cream unit (Esdeath) was a staple of the winter event. She serves as a premier stun/support unit. Her attacks freeze enemies, and she deals 1.5x damage to any target already affected by a freeze status. While she doesn't match the raw DPS of Shanks, her utility in slowing down fast-moving enemies is unmatched.
Best Traits for Secret Units
Rolling the right trait can double the effectiveness of your anime reversal secret units. While "Elite" is generally considered the best all-around trait, some units benefit more from specific stats.
| Unit | Recommended Trait | Reason |
|---|---|---|
| Hu Tao | Elite | Synergizes with her 50% damage boost when low HP. |
| Shanks | Elite | Maximizes his already massive base damage for full AoE clears. |
| Kyito | Critical | Necessary to trigger his 3x damage multiplier. |
| Amami | Speed | Allows her to apply her execute passive to more enemies quickly. |

Summary of Secret Unit Passives
Understanding how to trigger passives is the difference between a win and a loss in high-tier portals.
- Bleed & Burn Synergy: Units like Sukuna and Guts apply bleeding and fire DOTs. Hu Tao also applies a fire DOT. Pairing these with Kafka allows you to consume these DOTs for a 30% instant damage explosion.
- Health Management: Hu Tao gains 50% increased damage when her health meter is below 50%. Expert players intentionally let her health drop to this threshold before using her active skills.
- Map Control: Shanks' active skill stuns every enemy on the map for 8 seconds. This should be saved for "shielded" enemies or fast-moving bosses that threaten your base.
FAQ
Q: What is the fastest way to get anime reversal secret units?
A: The fastest way is to farm the Tokyo Portal Tier 3 for souls and items, while keeping a second account or a friend in a different lobby to "server hop" for NPC spawns like Hu Tao and Shanks.
Q: Is Hu Tao better than Shanks?
A: In terms of raw single-target DPS and DOT (Damage Over Time), Hu Tao wins. However, Shanks is generally considered the better overall unit because of his full-screen AoE and reliable stun mechanics.
Q: How often do secret unit NPCs spawn?
A: Hu Tao spawns every 15 minutes. The Red Hair (Shanks) NPC spawns every 1 hour and stays for 5 minutes. Use the Traveler NPC to track the exact timing.
Q: Can I get Igorus from the banner?
A: No, Igorus is a drop-only unit. You must play the Legend Stages on Nightmare difficulty for a 1% chance to obtain him as a reward.
