The monster appears to be more cloud-like in terms of appearance. Moreover, the center mass of which the three heads come out of bears a striking resemblance to a Cumulus cloud.
This card's Japanese name Tresragoon is the portmanteau of the word Tres (Three) and Dragoon.
Impetuous and Dust are both read as Funjin in Japanese, albeit the two words use different kanjis.
The explosions around this monster share the same color scheme and gestalt as Level Stars.
This is fitting given that this card is an Xyz Monster; every said monster depends on Levels for their de facto Summons.
Though hard to see, there is a green 57 inside the orange sphere on its main body.
