Chapter 5 is solely dedicated to the first 'fight' in Undertale, where we learn what each battle option does. Oh boy.

Everyone got sucked into a black & white area, with the dummy in front of them. There were also 4 buttons in front of them: FIGHT, ACT, ITEM, and MERCY. Mercy thought the MERCY button was named after her and D. Va and Frisk had to explain that the button isn't named after her (Undertale was released before Overwatch) but just summarizing up what that button's 'menu' did.

'I still think that button is important to me.'

'Think what you want, I won't stop you' Frisk said indifferently.

'So, let's go from the left. See the FIGHT button, with the knife? Press that to, well, fight.' D. Va told everyone.

'It would be ideal not to use that button, ever, but just in case...' Frisk nervously said.

'So, the FIGHTing system works by having a white bar slide across this box here, and you try aiming towards the middle. You only get one shot because the bar doesn't bounce back, so if you need to hurt someone, it would be best to hit there. Although it would be better if we didn't use that button.' D. Va said.

'What about this button, the one that says ACT and has a sound wave on it?' Winston asked.

'I was getting there. That is basically what you can do for/to it, other than FIGHTing. If we press this, you can see there is a choice between Check and Talk. Most encounters don't necessarily have Talk, but Check is always an option here. Who wants to volunteer and choose Check?' D. Va casually explained.

'Me!' exclaimed Tracer excitedly.

'Ok then, try it.'

Tracer pressed Check. Some text appeared. *ATK 0 DEF 0. *A cotton heart and a button eye *You are the apple of my eye. 'Oh, so it gives you information on the encountered enemy.' said Tracer, in mingled surprise and amusement, as though she expected it. Right.

'Ok, now it's the dummy's turn. Because it's a dummy, it can't attack, but other enemies can.' explained D. Va.

Everyone's SOUL appeared on top of one another. 'Oh, yeah, right. The heart is your SOUL. Try moving.' Frisk hurriedly said. However, the attack immediately ended, so nobody actually found out what their SOUL trait was.

'So to peacefully end this battle, somebody must choose Talk in the ACT menu.' D. Va said, putting emphasis on this.

'I'll do it,' Genji volunteered.

While Genji messed around with the menus, D. Va explained the other two buttons.

'So, the ITEM option, with the bag, is stuff you can use in a battle. Most ITEMs are food and stuff, but some help spare your opponent, which is relatively easy, no need to panic. For example, a stick will help spare dog enemies. Something about catching it or whatever.'

'Now this button here, the MERCY button, the one Mercy was squealing about' ('I did not squeal' Mercy muttered under her breath) 'The one with the cross,' D. Va continued, 'is for peacefully ending a battle, or sparing your opponent. You can run most of the time, and there is literally a Spare option. However, only use it when it is in yellow, otherwise they aren't ready to stop fighting. There's an exception later on, and I'll tell you when we get there. Otherwise, do the other thing I told you.'

Genji finally found the Talk button again, and pressed it. *You talk with the dummy, but it doesn't seem much for conversation.

*YOU WON! ('How did that happen?' Genji asked quietly.) You earned 0 EXP and 0 gold. 'Thanks for the nonexistent reward.' grumbled Genji (very quietly.)

So, this is the longest chapter yet, even though I skimmed over the explanations as much as possible, with 661 words. Not sure when the next chapter will come out, sorry. Also added mangopies to the edit team. (2 people.)
