  1. The Phantom - The Phantom and Devil 1/6th Scale Diorama Statue

    The Phantom - The Phantom and Devil 1/6th Scale Diorama Statue

    "When the Phantom moves, he shames the lightning..."

    From the moment fans first set eyes on the ghost that walks in his 1936 comic debut, they were captivated by the mysterious costumed crime-fighter. Unlike other superheroes, the Phantom relies entirely on his own natural strength, intelligence and enigmatic immortality. The iconic hero is often credited as the first costumed superhero, being the first to feature white, pupil-less eyes behind their mask.

    During the comic's early years, the colour of The Phantom's suit widely varied. The purple suit, which has now become the norm, has been seen ever since the comic started being published in colour in 1939. Lee Falk, the creator of The Phantom, orignally envisioned the suit as gray, but over time changed the suit to purple.

    The breathtaking 1/6th scale piece captures every detail of the unforgettable Phantom in the midst of a battle with an unknown enemy. Dual-wielding twin pistols as he and his loyal wolf, Devil, vault over the harsh jungle terrain, and featuring a removable gun blast for adaptable display, this statue is strictly limited, so fans of the Ghost Who Walks must act quickly before he disappears for good!

    Limited Edition - 350 Units Worldwide

  4. Marvel: Contest of Champions - Ghost Rider 1/6th Scale Diorama Statue

    Marvel: Contest of Champions - Ghost Rider 1/6th Scale Diorama Statue

    “We’re home and it’s high time for vengeance.”

    Summon the Hellfire into your collection with the Ghost Rider 1/6th Scale Diorama Statue by PCS Collectibles.

    Based on the hit mobile game Marvel: Contest of Champions, the Ghost Rider 1/6th Scale Diorama Statue captures Johnny Blaze as he drifts his Hell Cycle across the road, leaving scorched earth in his wake. With pure Hellfire and spite fuelling his journey, the Spirit of Vengeance lashes out with his chains to ensnare a sinner’s soul in his grasp and drag him back to Hell.

    The Ghost Rider 1/6th Scale Diorama Statue measures an impressive 11.25” tall by 23.5” long, and has been fully sculpted with a design inspired by by promotional character artwork to recreate his distinct Marvel Gamerverse style. Ghost Rider's costume includes his signature black biker jacket, black pants, and black boots, all accented with silver spikes and chains wrapping his right arm and torso. From front to back, the incredible Hell Cycle blends monstrous bones and mechanical construction together throughout its macabre silver frame. The flames surrounding Johnny’s skeletal portrait and left in the wake of his ride are all semi-translucent, incorporating reds, oranges, and yellows to emphasise the hellish heat. Finally, with a look of lethal glee on his face, the mystic champion is ready to deliver a soul-rending Penance Stare, ending any battle with ease.

    Ride the highway to Hell and set your collection ablaze with the Ghost Rider 1/6th Scale Diorama Statue.
