My Take On Ghost Rider (Without Zarathos) vs Joker (Highballed)
Johnny can matched and temporarily got the upper hand against Danny Ketch who at that time had completely absorbed the power of every Spirit of Vengeance that exists save six hosts, which amassed enough power to dethrone the Skyfather Yahweh and rule over creation, with Zadkiel utilizing that power was capable of shaking Hell, Heaven and Asgard in the process (Infinite Layers into Outerversal). Became the King of Hell, imbued with it's total power after dethroning Mephisto, who's strong enough to dwarf Ragnarok and stalemate a satiated Galactus. Making it consistent with Johnny w/o Zarathos pushing back and matching Galactus after the former just consumed a planet.
Possess God Physiology and Basic Magic, which grants Ghost Rider High-Outerversal resistance to existence erasure and thus, immortality negation for being able to kill other gods. Living in a state where fate and coincidences do not exists to resist causal manipulation, Hellfire which negates durability and target the soul and power nullification to counter Joker's haxes, can manipulate concepts and resists reality warping from Null.
