The answer before the background

Our recommendation

Crazy Defense Heroes has more than 20 unlockable heroes. The clearest publicly documented roster contains Ace, Artemis, Behemoth, Bentley Bear, Black Jack, Blink, Centurion, Cindara, Cobra, Drake, Dundee, Frostbeard, Furnace, Haunt, iRon, Knuckle, Oni, Oracle, Ruby, Sapphira, Shelly, Umbra, Valorius, and Wolfric, alongside your customizable Avatar. Heroes are movable battlefield units: deploy them where their attack pattern or special skill matters, then reposition them as waves change. The game’s official listing confirms the broad system—Hero, Tower, Spell, and Equipment cards—but does not verify a permanent hero-by-hero unlock schedule.

How the system works

Hero Cards versus your Avatar

Hero Cards are mobile combat units that can be placed and moved anywhere on the battlefield. They can take damage and faint, so their revival time matters when you rely on one hero to block a lane or finish a boss. Tower Cards work differently: they occupy predetermined tower spots and generally provide the stable ranged damage that keeps a defense running. (crazydefenseheroes.fandom.com )

Your Avatar is not simply another Hero Card. The documented card reference describes it as a separate, customizable battlefield unit whose base statistics come from Avatar Level and whose equipment changes its appearance and combat statistics. This makes the Avatar your consistent all-purpose unit, while heroes are selected for specific skills or matchups. (crazydefenseheroes.fandom.com )

  • Use the Avatar as your dependable frontline or utility unit.
  • Use Hero Cards to add a specialist effect that your towers cannot provide.
  • Do not judge a hero only by damage; mobility, aura effects, detection, and mana generation can decide a difficult stage.
Verified distinction

The official store describes four card families—Hero, Tower, Spell, and Equipment—and says the game has more than 20 heroes. It does not state that every named hero is available from the same chest or at the same progression point. (play.google.com )

Named heroes and practical roles

The following role labels are recommendations based on the documented special skills, not an official tier list. A hero can fit more than one role depending on card level, equipment, stage restrictions, and affinity. The community reference lists the names and skills below. (crazydefenseheroes.fandom.com )

  • Ace — mana-on-kill damage dealer; useful when regular enemies arrive in steady waves.
  • Artemis — critical-hit damage with Wrath of Zeus; a burst-oriented attacker.
  • Behemoth — durable single-target fighter with health regeneration.
  • Bentley Bear — mana generation tied to kills with rubies; a resource-focused attacker.
  • Black Jack — single-target fighter that generates mana.
  • Blink — mobile single-target specialist who can teleport anywhere on the map.
  • Centurion — straightforward single-target combat hero.
  • Cindara — area or wave-clear specialist with a chance to throw burning fireballs.
  • Cobra — straightforward single-target combat hero.
  • Drake — poison aura damage; strongest when enemies remain near him.
  • Dundee — straightforward single-target combat hero.
  • Frostbeard — slowing aura; a control and lane-management specialist.
  • Furnace — magic aura damage; useful against groups that stay close.
  • Haunt — poison-resistant hero; valuable in poison-heavy encounters.
  • iRon — area-damage specialist in community recommendations and roster references.
  • Knuckle — critical hits can freeze the struck enemy; a damage-and-control hybrid.
  • Oni — critical hits deal extra damage; a direct offensive specialist.
  • Oracle — reveals invisible enemies within range; bring him when stealth threats are present.
  • Ruby — attacks cause splash area damage; a flexible crowd-clear option.
  • Sapphira — critical hits trigger an arrow volley; combines single-target pressure with extra wave damage.
  • Shelly — single-target combat hero; practical for focused damage and manual targeting.
  • Umbra — straightforward single-target combat hero.
  • Valorius — increases friendly-unit damage within range; a support and damage-amplification hero.
  • Wolfric — straightforward single-target combat hero.
Roster uncertainty

The public reference currently exposes 23 named Hero Cards, while the official store uses the broader wording “more than 20.” Because the developer does not publish a dated master roster in the sources checked, this page avoids claiming that the community list is the final possible roster for every live event or platform build.

Unlocks and progression

How to get heroes without guessing

Hero acquisition is card-based. The official store says players collect and combine Hero, Tower, Spell, and Equipment cards, while the support center confirms that duplicate cards are automatically converted into resources and map pieces rather than being freely converted on first receipt. (play.google.com )

In practice, check every active source in the game: campaign rewards, chests, missions, event rewards, clan-related shops, and promotional claim screens. The support center confirms that the Clan Shop can contain cards as well as crafting materials, but its inventory refreshes with the clan season, so it should not be treated as a permanent hero list. (outblaze.helpshift.com )

  • Open the hero or card screen first and check the current fragment or map-piece requirement.
  • Read the reward preview before spending gems, tokens, or event currency.
  • Keep duplicate cards: they convert into progression resources and higher-star map pieces according to the duplicate rules.
  • Do not rely on an old guide that names a guaranteed chest or campaign stage unless the same reward is visible in your current game client.
  • Upgrade a useful lower-star hero only when it solves a real stage problem; save scarce materials when a better card is close to usable.

Team building

Choose by battlefield job

Start with the problem a stage presents. If ordinary enemies are overwhelming the map, pair a crowd-clear hero such as Cindara, Furnace, Ruby, or Sapphira with towers that cover the gaps in their range. If enemies are difficult to hold in place, Frostbeard, Knuckle, or Blink can buy time through slowing, freezing, or repositioning. These are practical recommendations derived from the documented skills, not developer rankings. (crazydefenseheroes.fandom.com )

For stealth threats, Oracle is the named detection answer in the roster. For poison-heavy stages, Haunt’s documented resistance is a direct counter. For a damage-focused formation, Valorius is the obvious support choice because his skill increases friendly-unit damage within range. Mana-oriented heroes such as Ace, Bentley Bear, and Black Jack make more sense when your deck depends heavily on frequent spell casts.

  • Use at least one hero that can survive contact if the map forces close fighting.
  • Add one form of crowd control when enemies bunch up or rush the exit.
  • Bring Oracle only when invisible enemies are actually present, unless his base statistics justify the slot.
  • Place aura heroes where the largest number of enemies or friendly units will remain inside their effective area.
  • Move heroes manually: a mobile unit loses much of its value if left on the first safe tile all battle.
Affinity reminder

Card affinities become relevant in Crazy Mode. The official help center describes a cycle in which Sun beats Moon, Moon beats Cloud, and Cloud beats Sun; Crazy Mode unlocks at Avatar Level 35. Check the stage and card icons before treating a favorite hero as universally best. (outblaze.helpshift.com )

Series context

Crazy Kings vs Crazy Defense Heroes

Crazy Defense Heroes is the expanded sequel to Crazy Kings, not simply a renamed version. Animoca’s ecosystem reference describes more card types, new heroes, buildings, spells, a guild system, and a larger progression structure in the later game. The current store listing likewise presents a four-card system and more than 1,000 levels, although store descriptions can be revised over time. (lightpaper.crazydefenseheroes.com )

If you are moving from Crazy Kings, expect the same broad tower-defense foundation but a deeper collection layer. Hero Cards are only one part of deck construction: towers provide fixed map coverage, spells provide timed effects, and equipment develops the Avatar. That is why a hero that looks strong in isolation may be less useful than a modest specialist that completes your deck’s missing function.

  • Choose the later game for the larger hero-and-card ecosystem.
  • Do not transfer old Crazy Kings unlock instructions to the sequel without checking the current client.
  • Compare actual card skills and stage requirements rather than character names alone.

FAQ

Common questions

How many heroes are in Crazy Defense Heroes?

The official store listing says more than 20 epic heroes. The current public roster reference lists 23 named Hero Cards: Ace, Artemis, Behemoth, Bentley Bear, Black Jack, Blink, Centurion, Cindara, Cobra, Drake, Dundee, Frostbeard, Furnace, Haunt, iRon, Knuckle, Oni, Oracle, Ruby, Sapphira, Shelly, Umbra, Valorius, and Wolfric. Your Avatar is separate from that named-card count. (play.google.com )

Who is the best hero for beginners?

There is no verified official tier list. As a practical starting point, choose a hero whose role fixes your current weakness: Ruby or Cindara for groups, Frostbeard for slowing, Oracle for invisible enemies, Haunt for poison resistance, or Valorius for team damage support. Upgrade the hero you can consistently use rather than waiting for a supposedly universal best character.

How do I unlock a specific hero?

Check the current card collection, chest previews, missions, events, and clan shop. Exact hero-specific routes are not permanently documented in the official sources checked, and event inventories rotate. Do not assume a guide’s old stage number or chest guarantee still applies.

Are heroes the same as towers?

No. Heroes are movable units that can take damage and faint. Towers are placed on fixed tower spots and generally provide more stable ranged coverage. A strong deck normally combines both rather than replacing towers with heroes. (crazydefenseheroes.fandom.com )

What happens when I get a duplicate hero card?

The support center says the exact same card at the same star level is automatically converted into resources and map pieces. Duplicate one-star cards provide map pieces for the next star level, with additional duplicate rewards for two- to four-star cards. (outblaze.helpshift.com )

When do hero affinities matter?

They matter in Crazy Mode. The official help center says Crazy Mode unlocks at Avatar Level 35, and the affinity cycle is Sun over Moon, Moon over Cloud, and Cloud over Sun. Check the icons on both the stage and your cards before choosing a lineup. (outblaze.helpshift.com )
