Facing Undyne in Undertale was one of my most intense gaming moments ever! 😱 This fish-warrior hits DIFFERENT depending on your route - I got wrecked multiple times before mastering her patterns. Seriously, her determination rivals yours! Whether you're pacifist or genocide player, I'll break down exactly how to survive her spears and music-pumping battles. Grab your courage - we're diving deep into Waterfall strategies! 💧

🛡️ Neutral Route Survival Guide

That first encounter near Sans' checkpoint had me sweating! When Undyne turns your soul green, IMMEDIATE shield positioning is key. Pro tip:

• Rotate your shield toward incoming arrows like a radar 🎯

• During red soul phases, memorize her attack sequence:

```

1. Diagonal spear thrusts

2. Spinning spear curtain

3. Spear rain (most brutal!)

```

I discovered two winning strategies:

• Fight Option: Wear her HP down gradually while surviving increasingly faster attacks. Her health bar vanishing doesn't mean victory - she'll keep attacking until collapsing dramatically!

• Flee Tactic: Dash during red phases! After 3-4 escapes, you'll reach the bridge where her armor overheats. Cue the most satisfying clang as she faceplants!

☮️ True Pacifist Friendship Path

This wholesome approach changed my entire playthrough! After escaping Undyne, sprint to the water cooler and BRING HER A DRINK 💧. Choosing this:

• Triggers adorable dialogue about "human refreshments"

• Unlocks her friendship letter later

• Opens Papyrus' cooking quests!

Skipping hydration forces you into Hotlands prematurely - major friendship FOMO! Trust me, befriending this passionate fish is worth the extra steps.

💀 Genocide Nightmare: Undyne the Undying

Y'all... this version still gives me PTSD. After eliminating every monster in Waterfall, you'll face Monster Kid. Strike him to trigger Undyne's heroic intervention. Then...

BAM! She resurrects as UNDYING with:

• 3x faster attack patterns

• New rainbow-spear combos 🌈

• Brutal 8-12 damage per hit

My survival kit:

1. Stockpile Cloudy Glasses (defense boost)

2. Memorize her "spiral of death" attack

3. Heal after EVERY sequence

Her final "HEROES NEVER DIE!" speech gave me chills - hardest boss fight since Sans!
