[WARNING: THIS VIDEO CONTAINS SPOILERS FROM THE GENOCIDE/NO MERCY ROUTE OF UNDERTALE]
This video features the boss fight against Undyne the Undying from Undertale. This particular boss can only be encountered and fought during a Genocide/No Mercy run and is basically an extremely buffed up version of the Undyne you can face in a Neutral or True Pacifist Route. The circumstances in which you encounter her are also very different during the Genocide/No Mercy run, as it's shown in the video.
Undyne the Undying is arguably the second hardest boss fight from Undertale, the other being the surprise final boss of the Genocide/No Mercy route, and is a very noticeable difficulty spike in that route (since the majority of the enemies and bosses there are usually down in one or two hits without fanfare). Undyine the Undying, instead, has very high defense and attack stats, uses the same attack patterns as Undyne, but more aggressively, and comes up with few new moves on her own (which mainly involves creating literal showers of spears you must dodge as circles of spears quickly close in on your position while others start forming)
