what ylm said

is everything deltarune/undertale to you

A lot is

We kinda already have those

Crystal of Creation and Crystal of destruction

I just had a game theory big brained idea moment
what if they created the crystals?

Sadly that's never going to happen

then I guess they’re 4 separate entities
they’re still canon tho

I'll explain an oversimplified creation of the bossfights universe.

Some sphere pops in out of nowhere and creates the bossfights universe. The Sphere called the creator makes a powerful bladesmith named (UNKNOWN INFORMATION) and also makes a companion named the banisher. The Creator soon gets bored and creates the crystal of creation. Of course Mr.Void had also appeared and made the crystal of destruction.

Actually that's not how it happened

So, not including information from later in my lore event, the crystals came first. They created the first universe, creator found the crystal of creation, and Mr Void found the crystal of destruction.

Stuff happened, and eventually creator and void fought. Creator won, and separated void from his crystal, but died in the process.

I dont really want to interfere with anyone else’s stories

Basically
Shadowy guy makes all the darkness in the universe
Light guy makes all the light in the universe

... we can just assume that they're closely associated with creation and destruction but aren't directly in control or controlled by them.

so wait, so He is associated with the Crystal of Destruction, cause he causes chaos and apocalyspe

Because he almost defeated Collector, He must be using the power of Destruction at his full potential, and now i have a few ideas for some other ocs

WAIT

WHAT IF THE TRAVELER HAD BROTHERS???????????????

Ok wtf are you talking about

about He, the main villain of the Apocalyspe Event? ya forgo?

Ohh "he" as in the character.

If you're gonna name a character like that you've gotta expect some confusion.

Anyway, the definition of destruction when referring to the crystal of destruction, is when all matter of an object stops existing.

So sure you can "destroy" something by shooting a Lazer at it, but that matter is simply converted to other forms.

However if you "destroy" using the crystal of destruction, the matter is just gone.

So stuff can be associated with the crystals but that doesn't mean it's using their power.

Ohhhhhhhh, but you gotta admit, Collector's power + Traveler's power is something the universe shouldnt see, so much power that he kicked He's ass
