[Lonk]

Elemental Hero Darknight
Level 9
DARK
Warrior/Fusion/Effect
ATK/2000 DEF/2400

1 "Elemental Hero", "Destiny Hero" or "Evil Hero" monster + 1 or more DARK monsters
This monster cannot be Special Summoned except by Fusion Summon. This card gains 200 ATK for each Fusion Material Monster used in this card's Fusion Summon. If this card would be destroyed, you can remove from play 1 DARK monster from either player's Graveyard to negate this card's destruction.
[Notes: If you chain an effect that sends a DARK monster to the Graveyard to the effect of a card that can destroy a monster you control, Darknight's effect is not activated.]

Elemental Hero Vulcano
Level 8
FIRE
Warrior/Effect
ATK/2800 DEF/1900

1 "Elemental Hero", "Destiny Hero" or "Evil Hero" monster + 1 or more FIRE monsters
This monster cannot be Special Summoned except by Fusion Summon. When this card is Fusion Summoned, inflict damage to your opponent equal to the combined Levels of the Fusion Material Monsters used in this card's Fusion Summon x200. Once Per turn, you can return 1 FIRE monster from either player's Graveyard to the top of the Deck to inflict 1500 points of damage.

Elemental Hero Fuzorblader
Level 4
LIGHT
Warrior/Effect
ATK/1800 DEF/1400

You can discard this card and remove from play, from both sides of the field and in both players hands, Fusion Material Monsters that are listed on an "Elemental Hero" Fusion Monster Card and Special Summon that monster from your Extra Deck (This Special Summon is treated as a Fusion Summon).
[Notes: Elemental Hero Fuzorblader itself is used as a Fusion Material Monster. If your opponent does not have any Fusion Material Monsters for any Fusion monster in your Extra Deck, you can look into your opponent's hand.)

Hero Substance
Normal Spell Card

Remove from play 1 "Elemental Hero" Fusion Monster in your Extra Deck. Special Summon 1 "Hero Substance Token" (Level 8, LIGHT, Warrior, ATK/? DEF/?). It gains the ATK, DEF and effect of the card removed from play. When this card is destroyed, Special Summon 1 "Elemental Hero" Fusion Monster that has been removed from play, ignoring the Summoning Conditions.
[Notes: This token's Continuous Effect can be negated. The Trigger, however, cannot since it completely leaves the field.]

Mirror Fusion
Counter Trap Card

While you control a face-up "Elemental Hero", "Destiny Hero", or "Evil Hero" monster, negate the effect of a Spell, Trap or Monster Effect that your opponent controls and destroy it. Afterwards, remove from play, from both Graveyards, Fusion Material Monsters listed on an "Elemental Hero" Fusion Monster and Special Summon that Fusion Monster from your Extra Deck (This Special Summon is treated as a Fusion Summon).
[Notes: The Fusion Summon is optional with this card's Effect]

IMO, it is pretty broke. Probably could put Heroes on a higher tier.

If the first two were Vanillas, they would still be at least Tier 2.
