Ok I found some au's that are like Blaster Sans, but aren't Blaster Sans. They look like and probably act like Blaster Sans but are from different au's.
Beast!Sans from Core Corruption
I don't know much about this au. But this is one of the three Sanses from it. Beast!Sans has three eyes, elongated pointer fingers, and looks kinda like a Gaster Blaster. If you wish to learn more about this Sans, look up Core Corruption Au or Beast!Sans.

Predator!Sans from Predatortale
This is another au I don't know much about. The first picture is what Predator Sans normally looks like while the other two are him in his half form and full form. I guess I would say this au is kinda like Horrortale, but minus all the creepy stuff. They eat humans in this au and all of the characters look like a beast of somesort. If you want to know more about this au, look up Predatortale or Predator!Sans.

Alright, this next au doesn't involve Blaster Sans or even Sans turning into a Blaster. This au is about the Blasters themselves.
The Blasters from Unexpected Guests
The Blaster(on the left) with the orange eyes is Papyrus's Blaster and the Blaster(on the right) with the blue eye is Sans's Blaster.
As you can see, Papyrus's Blaster has wings, is bigger than Sans's Blaster, and looks very friendly. The Blaster can also fly.
Sans's Blaster on the other hand does not have wings, but instead has a lot of spikes all over itself. The Blaster is smaller than Papyrus's but way more threatening looking (sorry if that doesn't make sense).
Unexpected Guests by Undertale Thingem(s)
If you watch the comic dub Unexpected Guests by Vade, it will explain the whole story way better than me. I will post the comic dubs on here so you all can watch it and see how it is. The comic dubs will be posted in the next chapter.
