Author's Note: SUP GUYS!

Chara: Sup bishes

CHARA, LANGUAGE!

Chara: Never-funking-ever.

=_= Fine, whatever. So I promised you guys a small surprise and this is it! A guide to Undercross because why not? And also because I just needed to right down the current non-spoiler material for how the multiverse works. AND! Character guides-ish? Kinda...

Screw it, yes, characters guides. Mini ones but they're still guides. Only for the characters that have appeared obviously xD

I'll shut up now and let you guys enjoy the horrible reference I made in the title ;D

Hitchhikers' Guide to the Multiverse

The Multiverse:

The Undercross multiverse is what I (the author) consider pretty unique in comparison to other UT multiverse stories (*cough cough* Underverse *cough cough*). Each single universe has timelines connected to it with ONE Prime Timeline each as the mother timeline. If you destroy a timeline that is not Prime, it won't affect the universe itself; it would just be one less timeline in the multiverse. Each universe has its own set of code that varied from the Classic! UT universe. The Classic Universe, however, is different than all the other universes.

The multiverse is also infinite, as it is modeled after the UT fandom. With each new universe idea brought up (no matter how silly), a new universe is added. The more popular universes are closer to the

Each universe also has its own set of code, however it is altered from the original Classic coding.

Destroying Timelines:

To destroy a timeline, the timeline MUST be unoccupied. As in, complete genocide. That's how Chara destroys the timeline in the game, after a completed genocide run. It's easier that way. Alternatively, you can mess up the code SO MUCH that the timeline collapses on itself and poof, gone. Usually, this process is quick if you know what you're doing, like how Error managed to kill off everyone so quickly, but the Prime Classic Timeline takes longer since the code isn't willing to give up. Also because it is the Classic Universe so it takes longer since it is deleting ALL OTHER universes and timelines.

Boundless:

When you are Boundless, you're not connected to any timeline, therefore, if something happens in your respective universe, you won't get affected. Basically, your soul isn't tied to any timeline or universe. This the condition Geno is in (other than Ink and Error). Being Boundless, though, has its pros and cons. You cannot get hurt outside of battle BUT you cannot heal properly. Not healing properly means that if you try to use healing magic, you cannot. If you try to use a healing item, you heal less than what you should've healed. However, if someone else uses healing magic on you, then you can heal but not as much as you should've.

Classic Sans

Stats: 1 HP 20 ATK 1 DF (Too good at dodging XD)

Personality: Laid back, chill, smart, kind, secretive, fast

Powers: Gaster Blasters (normal but with blue pupils), bone attacks, gravity magic, shortcuts/teleportation

Relationship to Others: He has a stable relationship with most of the gang, except with Fell but they tolerate each other. He doesn't really trust Error, for security reasons. He's good friends with Ink and Blue. He mostly trusts Geno, since Geno is most like him and they understand each other.

Weapon of Choice: Gaster Blasters

"Theme Song:" I'll Sleep When I'm Dead by Set it Off

Backstory: ?

*Extra: NONE

*Height: 4'9"

Fell

Stats: 15 HP 20 ATK 0 DEF (Too arogant to need defense but smart enough to have raised his HP more)

Personality: More brawn than brains, "mean" but reveals to be caring at some moments, reckless

Powers: Gaster Blasters (red eyes), black bone attacks, red gravity magic, shortcuts! :D

Relationship to Others: He hates everyone, some less than others. He hates Sans the most and hates Geno the least, since Fell respects him and is awed by Geno's experience in a living hell. The one person Fell doesn't hate is Blue, but he doesn't love him. Fell's scared of Blue due to… reasons.

Weapon of Choice: Sharp red bone he uses like a spear/sword or his newly acquired knife :D

"Theme Song:" Angels by Vicetone (feat. Kat Nestel)

Backstory: ?

*Extra: Way too good at combat and is a combat genius. Gets practice from Underfell.

*Seems to like Classic!Frisk a lot and shows to care for the kid.

*Gained a pretty good knife from a certain "fight" in the Classic Universe.

*Height: 4'10"

Blueberry

Stats: 680 HP 20 ATK 20 DEF (Has Papyrus' stats cuz from US)

Personality: sweet, "naive," "innocent," caring, is a lot like a Pacifrisk, is really smart and cunning when not panicking

Powers: Light blue bone attacks and "YOU'RE BLUE NOW" attack

Relationship to Others: He loves everyone. He's tried to establish good relationships with everyone, and that has worked but with two exceptions: Fell and Error. Blue doesn't really understand Error and Error doesn't understand Blue. And for some reason, Fell acts weird around Blue and whenever Blue notices and asks about, everyone seems to change the subject.

Weapon of Choice: *Doesn't really like to hurt anyone*

"Theme Song:" What a Wonderful World by Louis Armstrong

Backstory: ?

*Extra: DO NOT TAKE HIM AS A NAIVE LITTLE KID. HE IS SMARTER AND CLEVER THAN WHAT HE SEEMS. IT'S ALL AN ACT. WAIT UNTIL HIS TRUE COLORS SHOW!

*Height: 4'5"

Error

Stats: ? HP ? ATK ? DEF (All of his stats are glitched)

Personality: Distanced, smart but not wise, NOT open-minded and is usually "blind," secretly cares for Ink but as family, fast thinker(ish), leader(ish), insane, childish at times

Powers: Gaster Blasters (black colored, glitched, red eyed, white pupils), strings, red bone attacks, dimension hopping

Relationship to Others: He is really distanced from everyone, even Ink. He's more open to Ink and he tolerates Geno and pretty much everyone else. He cares for Ink like a brother. He really just doesn't care if anyone dies though he'll show sympathy just for the sake of everyone else.

Weapon of Choice: His blue strings

"Theme Song:" My Demons by Starset/ Brandy New Day from Dr. Horrible's Sing-Along-Blog

Backstory: ?

*Extra: While Error actually does care for Ink, he still hates him. This is a result of being insane and hypocritical.

Relationship to Others: He trusts the others, even Error, but he is still doubtful of all of them.

Weapon of Choice: Easy bone attacks.

"Theme Song:" Brother by Falling In Reverse

Backstory: (*REFER TO AFTERTALE COMIC BY CQ*) But Geno ends up destroying his Universe and moves to the Classic Universe's Void. There, he safely watches the progress of the Prime Timeline.

*Extra: Manages to stay alive even though is perpetually dying through bring Boundless however that means he can get hurt in battles but is unable to heal properly.

*Deadly afraid of knives though

*Height: 5'

Ink

Stats: ? HP ? ATK ? DEF (He's a Multiverse god, whadya expect? XD)

Personality: Happy, kind, caring, smart, strategic, usually over excited, forgiving
