DEATH BATTLE: Archer EMIYA VS Hakumen

Fate vs BlazBlue

Connections:

Both are white-haired swordsmen who are the future versions of the main protagonists of their series (Shirou Emiya and Jin Kisaragi respectively). They hailed from an alternate universe where they're summoned back into the past to course correct a mistake and catastrophic event that doomed their respective timelines

Both specialized in bladed weapons which grants them unique abilities in combat (Kanshou & Bakuya daggers and Slaying Demon: Ōkami respectively)

Both have "Steel" as part of their iconic battle chants to activate their ultimate techniques (Emiya's Noble Phantasm Unlimited Blade Works and Hakumen's Timekiller)

Both are considered as "Legendary Heroes" in some shape or form (Emiya being a Heroic Spirit/Counter Guardian and Hakumen being one of the Legendary Six Heroes)

Bot have a history of being servants and fighting alongside or against current descendants of royal bloodlines (Rin Tohsaka and Rachel Alucard respectively)

Both had a confrontation with their past selves in combat whom they deeply loathed before ultimately forming a mutual respect for them (Emiya's dislike towards Shirou's naivete on the harsh realities of being the "Hero of Justice" and Hakumen's dislike towards Jin's condescending arrogance and asshole-ish behavior which had often cost him the trust of his family as well as loyal friends and allies)

Although cold and reserved due to their experiences of living in a world where they had tragically lost everyone and everything they hold dear which changed them yet they never lost their selflessness and compassion for others as it never stopped them from continuing to do what was right and to fight for a better future

After finally succeeding in preventing the doomed future of the titular character's respective worlds from suffering the same fate like their own previous timeline where they've once resided from; they're both able to finally rest at ease and be in peace, but will continue upholding their principles in continuing their fight to ensure that the peace they longed fought for remain preserved
