What is Evil Demon in UTDX?

Evil Demon is a Secret rarity unit based on Janemba, the pure-evil villain from Dragon Ball Z: Fusion Reborn. It was added as part of the Festival Part 2 update alongside 10 other DBZ-inspired units. What sets it apart from most Secrets is how you obtain it not from gacha banners, but from a permanent event mode called Otherworld Hell.

The unit can be evolved into Evil Demon (Rage) using a Hell Sword, which is currently obtainable through the Otherworld Shop using Otherworld Coins. Evolution requirements beyond this are still being confirmed by the community, but farming the mode actively is the priority.

How to Get Evil Demon?

Evil Demon drops from the Otherworld Hell game mode, a permanent Calendar Event in UTDX.

Accessing Otherworld Hell:

  1. Open the Events tab from the left-side menu in the lobby, OR
  2. Walk up to the Evil Demon NPC in the lobby and interact with it.

Pity System:

  • Base drop chance: up to 5%
  • Pity cap: 20 runs pity increases by +1 per run
  • At pity 20, you’re guaranteed to receive Evil Demon

This is one of the most player-friendly acquisition methods in UTDX. You don’t need luck-based banner pulls just consistent farming.

Otherworld Hell Mode Explained

The Otherworld Hell mode is a boss fight with a deception mechanic. At Wave 10, three Janemba clones spawn at three fixed positions on the map one at the start, one mid-lane, one near the end. Only one is the real Evil Demon; the other two are decoys.

Key mechanics to know:

  • Touching or killing a decoy resets all three boss HP bars to full
  • Evil Demon is Crit-Immune avoid crit-focused builds
  • Evil Demon is susceptible to DoT (Damage over Time) effects this is your key advantage
  • You earn Otherworld Coins per run, spent in the Otherworld Shop

Two farming strategies:

Strategy 1 — Single Focus (Solo/Small Team): Stack all units on the first boss spawn position. Clear waves fast, then dump all DPS into one target. You have a 1-in-3 shot, but runs are quick.

Strategy 2 — Split Burn (4-Player Coordinated): Split into two groups targeting two bosses simultaneously. Land simultaneous kills to raise your correct-target odds to ~66%. Requires team coordination but cuts your pity grind significantly.

Best Units for Otherworld Hell

Since Evil Demon is Crit-Immune and DoT-susceptible, your team composition matters. Here’s what works:

UnitRoleWhy It Works
King Sailor (Unrivaled)DPSTop-tier raw damage output
Triple Threat (Unrivaled)DPSExtremely high burst potential
Alpha Devil (Omega)DPSStrong sustained damage
Devil Hunter (Mercenary)DPSDoT synergy via Bleed/Burn combos
Virtual IdolSupport/BufferDamage amp for whole team
BulmoFarmPassive income generation
FastcartFarmEssential economy unit

DoT-heavy setups (Bleed → Burn chains via Devil Hunter) are especially effective since Evil Demon takes bonus damage from persistent damage effects. Avoid stacking crit rate it’s completely wasted here.

Evil Demon Evolution: Evil Demon (Rage)

Once you’ve obtained Evil Demon, you can evolve it into Evil Demon (Rage) using a Hell Sword item. Hell Sword is obtainable from the Otherworld Shop using Otherworld Coins earned through the mode.

Complete the following one-time Otherworld missions to earn bonus Otherworld Coins for the shop:

  • Evolve Evil Demon
  • Evolve Angel Born in Hell
  • Evolve The Drink (Rage)
  • Evolve Super Roku (Halo)
  • Evolve Limit Breaker Prince
  • Evolve Fused Warrior

Full stat breakdowns for Evil Demon (Rage) are being documented by the community as of June 2026.

Pro Tips

  • Run Strategy 1 when solo don’t wait for a team; fast single-target runs build pity quickly
  • Prioritize DoT units over crit dealers Crit-Immune makes crit relics worthless in this mode
  • Farm all missions one-time Otherworld missions give bonus coins to unlock the Hell Sword faster
  • Use the Event NPC shortcut the Evil Demon NPC in the lobby is faster than navigating menus
