This card can be considered the Fusion counterpart to "Crystal Wing Synchro Dragon" and "Dark Requiem Xyz Dragon" as they all share the following similar traits:
They are the evolved form of one of the Four Dimension Dragons.
They have 500 more ATK and DEF than their base counterpart.
They are at least 1 Level/Rank higher than their base counterpart.
Like its previous form, this card has several distinctions from the other evolutions of the Four Dimension Dragons:
It is the only evolution to not have 3000 ATK. (Instead, it has 3300 ATK)
It is the only evolution to not be 1 Level/Rank higher than its base counterpart. (Instead, it is 2 Levels higher than "Starving Venom")
It is the only evolution to specifically require a monster from the archetype its owner uses as one of its Materials. (In this case, Yuri's "Predaplant" monsters)
This makes "Greedy Venom" the least splashable of the evolution trio.
It is the only evolution without an effect that increases its ATK.
It is the only evolution that was not first summoned while its owner was in unison with Yuya (though he was awakened at the time Yuri summoned "Greedy Venom").
It is the only evolution that did not finish off the opponent the turn it is initially summoned for the first time. ("Dark Requiem Xyz Dragon" caused the effect of "Destiny HERO - Dynatag" to end the duel between Yuya/Yuto and Aster Phoenix in a DRAW)
However, Yuri did manage to finish two of his three opponents off with this card.
