Mastertale Sans

Mastertale Sans used to be a normal Sans, but his AU was attacked by Error Sans. Sans tried to fight him off, and was soundly defeated. He somehow survived the attack, and went through Error's portal before it closed. He ended up in the Anti Void, where he hid for a while. (Due to this, he sometimes has an Error sign floating around him). While in the Anti Void, he learned about other AU's, and how to counter their abilities. He started looking through windows to other AU's. He also gained special abilities in the Anti Void, due to it's effects on him, but also went slightly insane. When he learned enough, he formed a portal and escaped, going to the remains of his old AU. Since his old AU was destroyed, he used his newfound powers to recreate it, infusing all it's members with his knowledge. (Note: The other characters only know about varients of themselves. (Ex: Mastertale Asgore knows facts about UF Asgore, but not UF Toriel.) He renamed the AU "Mastertale", and started traveling the AU's looking for more knowledge and abilities, meeting many new people along the way. He originally existed in the multiverse until he found out another plane of existence called UT:MM. He appeared and examined the code in the world. He eventually created his own data compilation of the plane of existence, that used things he originally came from, which was the Multiverse of course. Mastery Sans examined the code for a while, until he had found out everything he could about the Multiverse. When he returned, he was even stronger than before. His main goal is to learn everything in the Multiverse, and eradicate evil, no matter what it takes.

Appearance:
Mastery Sans wears a dark grey hoodie, with blue markings on it. He has a triangular device attached to his chest that allows him to teleport items from his private collection to him. He wears a hologram projector on his right eye, that projects a screen for him. The hologram allows him to instantly find out anyone's backstory, abilities, and weakness (Note: He can still copy it without the device, but it takes him longer.) He also is sometimes seen with a tablet either floating behind him, or in his hands.

Personality:
Mastery Sans can be aloof at times, and is very sarcastic. He also is prone to flashbacks to his seemingly everlasting time in the Anti Void, and during those he will refuse to talk, move, or even react to anything. However, he can also be very kind and accepting. He is still scarred from Error's attack on his AU, and never has forgiven him for that.

Abilities:
Copy and Paste: Mastery Sans can copy his opponents abilities, and use it against them.

[Note: Abilities he cannot copy are as follows: ''He cannot erase worlds that he did not create, he cannot use Nightmare's tentacle powers (unless he ate an apple), he cannot use powers from AU's he hasn't heard of without research, he cannot use soul traits unless he has the soul (Ex. Bete Noire's fear abilities) He also cannot copy the powers of those who are stronger than him. Mastery Sans is Low Multiverse Level (2-C)]''

Instant Counter: Mastery Sans can dodge/counter any ability he has copied, and will strike back with a move that you do not expect.

Genesis: Mastery Sans can recreate AU's, but not create new ones. This takes a lot of energy though. He also has complete control over the inhabitants of the AU.

Portals: Mastery Sans can open a portal to any AU.

Regeneration: Mastery Sans can regenerate near-fatal wounds in an instant.

Supernatural Speed: Mastery Sans can move just under the speed of light, letting him go about 295,000 km/s.

Body Control: Mastery Sans has complete control over his body, and can modify it if needed.

Mastertale Papyrus:
Papyrus is Mastertale Sans' younger brother, and is the only one he confides in about his time in the Anti-Void. This version of Papyrus is less naive, and remembers everything (unlike the other inhabitants of Mastertale). Sans completely trusts in Papyrus, and vice versa.

Mastertale Gaster:
Mastertale Gaster is Sans' father, and survived Error's attack, due to him being in the Void. When Sans recreated Mastertale, Gaster taught him how to properly use his new powers to become as strong as possible. Due to this, Sans spent a lot of time in the void.

Ink Sans:
Mastery Sans talks with Ink Sans a lot. When Mastery first started traveling the AU's, Ink talked with him, and helped him recover from his experience in the Anti Void. They talk regularly, and are great friends.

Aftertale Sans:
Mastery met Geno during his travels, and they got to talking about their experiences.

Godverse Sans:
When these two met, Mastery attempted to fight the Sans. Throughout the fight however, he didn’t come close to hitting him once and the Sans just constantly dodged. Knowing fighting on was pointless, he decided to retreat. Mastery was a bit suspicious of Godverse because of the fact he had no idea who he was, and couldn’t sense anything about him. The two are on neutral terms.

Cross Sans:
Mastery has shown interest in helping him get his AU back, but was concerned by X-Chara's possesion of Cross, and stepped back.
