- Gray is the first Dozerfleet superhero to be part of Gerosha canon (Earth-G0, 2001), predating Ciem (Earth-G3.1, 2005) by four years.
- In non-Gerosha canon, he is predated by Replox (2001) and the Stationery Voyagers (2000), the latter of which spun-off the Cherinob continuity (2015). Also predating him are Redundant Man (2000), Pollo Dehielo (2001), the human dilophosaurus known as Spitter-Man (1996), a Pac-Man knock-off called Puck-Man who was an orange hockeyball (1994), the Rainbow Jockeys (1998), and the Defenders of Stick-Man Village (1993).
- Gray's theme song in Freedom's Apparition is "Freedom Fighter" by Creed.
- While he may be old, he ages slowly. He's also a powerhouse with the Marlquaan on his side. He runs out of stamina quickly when Phased, yet is a force to be reckoned with even without his sword. He has been dubbed "Puritan Thor" by some.
- Most of his rogues gallery consists of references to Hawthorne literature, which comprises the Gerosha universe's cosmic composition in much the way Marvel utilizes Norse mythology.
- Eqquibus is a reference to a painting: "The Nightmare."
- Chillingworth is named after Roger Chillingworth, and is the most cold-hearted enemy of both Gray and Hea.
- The Society of the Icy Finger, which spawned Chillingworth and most of the rest of Gray's rogues gallery, is like the Dozerfleet version of Hydra.
- They have disowned the Shrouded Entity, who went mad with power and now imagines himself to be Beelzebub incarnate. Shrouded Entity works in ways similar to Mephisto, and was referred to as the "Black Man" in The Scarlet Letter.
- Other enemies of the Gray Champion include Feathertop, Bosom-Serpent, Brackett, Hibbins, Marblefaun, Rapaccini, and Blackveil; the last of these operating like a variation of the Pied Piper.
- Gray is considered one of the most powerful Dozerfleet superheroes, along with Cocklebur and Extirpon.
