The Sans character in Undertale
Sans is one of the most iconic characters I've seen in gaming. He's a short skeleton who rocks a blue hoodie and has this permanent grin that can be either friendly or terrifying depending on the situation. I love how he starts off seeming like just a lazy jokester who loves making puns, but there's so much more beneath the surface.
What makes Sans truly special in Undertale is his hidden depth. While he puts on a laid-back act, he's watching your every move. I've noticed he's incredibly smart and powerful, but chooses to stay in the background most of the time. He only shows his true abilities when he absolutely has to.
The way Sans breaks the fourth wall and remembers things across different playthroughs adds another layer to his character. He knows when you've reset the game and remembers your past actions. This makes him feel more real and unpredictable than your typical game character.
Soul modes and attacks of Sans
Your soul has two main modes in battle:
| Soul Mode | Properties | Movement Style |
|---|---|---|
| Blue Soul | Affected by gravity | Jump-based movement |
| Red Soul | Free-floating | Moves in any direction |
Sans uses three main types of attacks that I've faced countless times:
Dragon Skulls (Gaster Blasters):
These giant skull-like weapons shoot devastating white beams. You'll need quick reflexes to dodge them.
Psychokinesis:
Sans can grab your soul and slam it against the walls. The key is to watch for the blue flash that signals this attack.
Bone Attacks:
These come in two flavors:
- White bones hurt on contact
- Blue bones only hurt if you're moving
How to fight Sans in Bad Time Simulator
Fighting Sans is no walk in the park! I've spent countless hours mastering this battle. The key is staying focused and learning his patterns. Don't let his casual attitude fool you - he's deadly serious about taking you down.
Here's what I've learned about surviving the fight:
- Watch your health bar - It drops fast if you're not careful
- Use healing items wisely - Save them for when you really need them
- Pay attention to dialogue - Sans might drop hints about his next move
- Stay determined - You'll likely fail many times before succeeding
The battle interface gives you four main options:
- Fight: Use this to attack Sans
- Act: Try different actions (though they rarely help)
- Item: Access your healing items
- Mercy: Don't bother - Sans won't accept it
