It and Euoplocephalus are the only known TCG-only armored dinosaurs. Unlike Euoplocephalus, Iguanodon wears Spectral Armor more similar to the design of other Grass Dinosaurs in the anime.
While both anime Grass Spectral Armor suits have a large shoulder plate with 8 spikes and a hip plate with 4, Iguanodon has a more reduced shoulder plate with 6 and a hip plate also with 6. The spikes are also below the Space Pirate emblem instead of above them, and what is seen of the tail armor plate shows thicker spikes than normal.
As its card's text is unreadable, it is unclear if it has the [Spectral Armor] summoning restriction ability of most Spectral Armor Dinosaurs, or if it lacks it like the SAS Spectral Armor Dinosaurs.
