The gloves on the gilded version of Ivan are a Bleeb from Cloudstone, another game by Playsaurus.
Hecatoncheir's description mentions Ivan: You share a drink with Ivan before visiting the monument. You both put up your dukes and start to brawl, trading blow after blow. The energy surrounding this ancient urges both of you to keep fighting, though you're both beaten and battered.
On games website coolmathgames.com, Ivan is a coffee addict, and his upgrades revolve around coffees, not beer. This is probably so that kids on this site don't see a beer addict. The icon of Ivan's skill, Powersurge, is replaced with the icon of Heaven's Hand, which may because the original icon depicts a red, horned skull.
This hero, The Maw and King Midas are the only heroes in the game to have 6 upgrades rather than the standard 4 or 5.
