God of War Ragnarok is filled with Easter eggs, such as how Ksavir's poetry references other PlayStation exclusives like Bloodborne, Horizon, Ratchet and Clank, and more. Indeed, it's a nice touch, but perhaps one of the least expected references hints at Kratos' time in Earthrealm.

As many may remember, Kratos appeared in Mortal Kombat 9 as a character for PS3 and PS Vita owners. He has also appeared in Soul Calibur and the PlayStation All-Stars battle royale game, and while the canonization of the latter is completely on the nose, it's entirely possible that Kratos' time in Mortal Kombat 9, Soul Calibur, and possibly even Fortnite is also officially canon, if not as directly.

Mimir will eventually ask Kratos about his time in tournaments, describing a series of opponents that directly canonize PlayStation All-Stars in God of War Ragnarok. However, there is some key context in this conversation. The fact that Mimir separates Kratos' homeland from the tournament in question makes it clear they're not talking about Greece, which Kratos follows up with saying he fought in "many contests." The implication here is that Kratos fought in many contests that did not take place in Greece. Mimir describes PlayStation All-Stars next, though some of these references could easily double as Mortal Kombat or Soul Calibur characters, and with this in mind, Kratos says he "would not speak of this."

Sure, Kratos may just be avoiding talking about PlayStation All-Stars, because that's who Kratos is, but his hesitation and response don't really make as much sense in this case. However, if factoring in how unlikely it is for God of War Ragnarok's Kratos to directly talk about Mortal Kombat, Soul Calibur, or Fortnite without serious royalties or some contract being involved, it makes it very likely that the avoidance and many contests reference, in turn, canonize his appearance in these franchises.

Either way, it doesn't change much about Kratos in his current state. Prior to the God of War Norse Saga, Kratos was an angry god-killer who would fit perfectly in Mortal Kombat and Soul Calibur; perhaps not so much now. No one really wants Kratos doing a Fortnite dance to be canonized either. It remains to be seen what's next for the God of War, and while more crossovers are certainly welcome, their canonicity remains largely vague if somehow unavoidable.

God of War Ragnarok is available now for PS4 and PS5.
