Okay, let's go from lore to oldest to newest.

Mother Void lore:

Mother Void was created by Null along with 4 other creatures to help create the multiverse, these other 4 creatures being Happyness, sadness, Johnny maemo and j3ff m∆th

Mother Void to help in the creation of the multiverse she created the VOID which is practically the void of the amazing world of gumball XD

Mother Void also created the prototype of what a living being would be, this prototype being ZardyDav and ZacaryGab

Of Mother Void's brothers, the one she gets along with the best is Johnny Maemo. (They have a lot of things in common lol)

Mother Void has a strange fixation with sharks to the point that she has a room in her house filled with nothing but shark stuff like plushes, paintings, etc.

Mother Void's powers are:

• Open portals across the multiverse

• Summon object

• Make pacts (she doesn't use this power much because she doesn't like making pacts)

• Summon flying eyes

• And read minds

ZardyDav lore:

ZardyDav or so Zardy is the first prototype of what would be a living being

Zardy was born and lives in the Void and inherited some powers from Mother Void such as opening portals, summoning objects and making pacts.

Zardy likes to wander around the multiverses to make random graffiti to make the beings of the universe he went to confused.

Some things he did throughout the multiverse that ended up changing his appearance a bit were:

When he entered the universe of hazbin hotel/helluva boss with his family to spend a vacation there, his horns took on the pattern of the IMPs' horns.

When he visited the One Piece universe he made a replica of Luffy's hat and CLONED THE MAGMA FRUIT (I don't know what its name is) and that's why his arms have magma textures.

But the thing that changed him the most was when he went to visit the murder drones universe ON THE SAME DAY THAT CYN WAS KILLING ALL THE HUMANS, And how did it end you wonder? Well, Cyn found him and Zacary and ended up ripping off Zardy's legs and one of Zacary's arms, but then a creature called N0P appeared and Zardy confessed to him to make a pact with him. And so N0P accepted, and after the pact, Zardy asked N0P to give him new legs and a new arm for Zacary, thus leaving them both with those robotic parts on their bodies.

Zardy's best friends are Zacary, Corrupeted, Demon Carns, Bob and Angel Furby.

Zardy's powers are:

• Open portals across the multiverse

• Summon objects

• Make pacts

• Summon two shadows to be his servants (the names of these shadows are zar and dav)

• Make your arms literally turn to lava

• And have a third eye under his bangs (that's all lol)

• And also have a pocket dimension where the beings he made a pact with stay (the place would be similar to a party room

Unlike his mother, Zardy likes to make pacts. The creatures he made pacts with are:

• Happyness (He didn't know it was his uncle at the time he made the pact)

• Sadness (same thing as happyness)

• N0P (because of the legs thing)

• Bill cipher (He did this just as a joke to see who has the greatest pact power between the two of them XD)

• Red (godzilla nes Creppypasta)

• Willian Afton (just to put him in a purgatory worse than UCN)

• Mimic from fnaf (He thought it would be funny to make the pact with THE FUCKING MIMIC)

• Auditor (just to get the halo for yourself)

• Undying (To end his suffering)

• Silly billy (Same reason as undying)

• Gorefield (He offered him a lasagna and Gorefield accepted XD)

• Trollface (because YES)

• "Bon" (Just because he wanted an endo from bon's burgers)

• Ink demon (Because he wanted the power of ink to [REDACTED])

And because of the pacts he has practically 14 stomachs, so every day he eats a mega burger of a bunch of crazy stuff

ZacaryGab lore:

ZacaryGab or just Zacary was the second creation of mother void

Unlike his brother, he has mental health.

Zacacy had a similar appearance to Zardy but then he ended up in the Madness Combat universe and for some unknown reason his appearance became the same as the characters from madness combat.

Zacarias hates Tricky (I would even dare to say that he hates Tricky more than Hank)

Zacary doesn't have as many powers as the others in his family, but his robotic arm can help him a lot.

Zacary can partially control madness, just enough to control his impropriety limit in his body.

His powers are:

• Open portals across the multiverse

• Summon objects

• Control the madness

• And all the things your robotic arm does like (turning into a firearm, a bladed weapon or even AN ATOMIC BOMB)
