• The "Elemental Heroes" designs were mostly based on American super heroes; the inspiration for Wildheart was most likely Ka-Zar of Marvel Fame or possibly Anthro or Kamandi of DC (the first and the last boys on earth respectively). Or possible Apache Chief from the DC Super Friends

• In addition to "Cyclone Boomerang", this has an anime-only support card known as "Wild Half".

• This card's effect/level/atk are the same as "Tenkabito Shien".

FusionEdit

"Elemental Hero Wildheart"'s fusions look as if he is wearing his Fusion partner's armor/costume.

"Elemental Hero Wildheart" fuses with:

• "Elemental Hero Bladedge" to form "Elemental Hero Wildedge".
• "Elemental Hero Necroshade" to form "Elemental Hero Necroid Shaman".
• "Elemental Hero Avian" to form "Elemental Hero Wild Wingman" and "Evil Hero Wild Cyclone".
