This card is used by Aster Phoenix and since he is the anti hero to Jaden Yuki, then this monster could be the anti-thesis to "Flame Wingman". Also, this card is one of Aster's trump cards while "Flame Wingman" is one of Jaden's trump cards in the anime.
These monsters share some resemblances. "Elemental HERO Flame Wingman" has a dragon head on his right arm and "Dragoon" uses a dragon head for a shield on its left arm and has a dragon head on its chest plate.
These cards have similar effects in which they can inflict damage equal to a monster's ATK after they destroy them. The effect of "Dragoon" allows it to destroy a monster to inflict damage, but also restricts by not allowing it to attack, the effect of "Flame "Wingman" requires it to destroy a monster by battle to activate its effect.
"Dragoon" is a type of mounted infantry that carried a type of firearm which could relate to this monster and its effect since the dragon head shield appears to be a cannon.
This card's Japanese name is a pun ("Dragoon D-END"), as it was the last "Destiny HERO" related card to appear in the Yu-Gi-Oh GX anime.
