What was your biggest “Oh ****” moment in Undertale

Too many for a poll so i’m putting a few examples here:

Beat drop on Hopes and Dreams

Photoshop Flowey appearing

First encounter with Mettaton

Photoshop Flowey healing all damage

Sans’s first attack

First time in the True Lab and seeing Memoryhead

Strangely enough, I have experienced none of these. I just didn't go in blind.

Asgore destroys the mercy button and his theme plays
Still one of my favorite boss fight intros in gaming

Lemon bread.

That’s all I need to say.

I was low on HP and was like, “Hey, a save point!”

Oh yeah also hearing amalgam for the first time. Vastly underrated track.

Seriously, amalgamation and here we are are so eerie and unsettling

My first Oh F#ck moment was in Omega Flowey’s battle, because i thinked he was a secret boss or somethingalike, because i thinked Asgore was the final boss on neutral. Also Lemon Bread’s attack

Flowey does give off secret-and-ultra-super-hard-boss vibes (like Akuma)

Really? Akuma?
All I'm saying is that Akuma feels more intimidating then photoshop flowey
At least in my opinion

Ok then how about Void (Double Secret Final Boss) from KSA

What are you guys talking about

i don’t know anything about these anythings you are talking about

I haven't played star allies :(

Akuma is the secret boss from Street Fighter II Turbo that you unlock by beating all enemies except for the final boss without losing a life, and he replaces the final boss

Void is a much much harder version of the final boss of Kirby Star Allies, Void Termina. They are fought in the Boss Rush/Endurance game mode called the Ultimate Choice. To fight them, you must:

  1. Beat Story Mode
  2. Beat any of the first 5 difficulties of The Ultimate Choice to unlock its 6th and 7th difficulties (Fiery Showdown and Infernal Crisis, respectively)
  3. Beat the Fiery Showdown or Infernal Crisis difficulty to unlock the secret Soul Melter difficulty
  4. Beat the Soul Melter difficulty to unlock the double-secret difficulty, Soul Melter EX
  5. Battle your way all the way up to the final boss, which will be Void

Ohhhh so i know Void i’ve beaten it

Didn’t noted that KSA meaned Kirby Star Allays


BRO I CANT EVEN BEAT SOUL MELTER AND THERES A SOUL MELTER EX?!

Me after learning this: :skull:

Just use Stone, it’s attack provides I-frames

Another strategy is to use Ice’s defense, it makes you invulnerable and deals damage.

But let’s not stray too far from Undertale and Deltarune, please

Got it, mine was probably seeing Memoryhead for the first time and hearing the music drop for Hopes & Dreams

Are you sure?
