Description

Introduction

Mercer: Cú Chulainn, The Lancer of Fate/stay night.

Necro: When it comes to loyal warriors, there's no better. They'll take their orders, complete the job and-

Mercer: SPEAR you the details!

Necro: Oh boy, ....it's gonna be one of those episodes, eh?

Mercer: It sure is! He's Necro and I'm Mercer!

Necro: And it's out job to analyze their weapons, armor and skills to find out who would win...

Mercer: ... A Death Battle!

Undyne Spears You the Details DEATH BATTLE!

(Cue: Spear of Justice)

Necro: Justice. Might. Determination. These three words perfectly embody the Captain of the Royal Guard and protector of the Underground, Undyne. Even when she was a child, Undyne was always striving to be the strongest for the sake of protecting her fellow monsters, even if she was a little over zealous at times.

Mercer: Like the time she attacked a mail man by accident when she was out beating up "bad guys" with her idol, an old turtle man named Gerson. Poor guy.

Necro: Despite her rough-around-the-edges attitude, her gusto and sheer will to protect others lead her to challenge the King of Monsters, Asgore, to a one on one duel, in which she failed to land a single attack on the king.

Mercer: Despite her humiliating defeat, Asgore, the real one that he is, offered to train Undyne. She took his offer, and eventually, through her hard work and his guidance, she became the Captain of the Royal Guard.

Necro: And as the Captain of the Royal Guards, Undyne has proven herself time and time again to be one of the most powerful monsters in the Underground, and a worthy protector of her fellow monsters.

Trivia

• The connections between Lancer and Undyne is that both are prideful warriors who use a spear in battle, putting their life and soul into protecting their kingdoms/homelands. They both have moves meant to be one hit KOs relating to their spears, which are special and unique in nature.  Both are super resilient, even when they are about to die they somehow pull themselves back together to fight even harder.
• This battle would be hand drawn
• If this fight had an OST, it would be called "不滅 (Fumetsu)" or Undying, in reference to Undyne's transformation, and their shared nature of simply surviving death.
