This came out much larger than anticipated...
But I am pretty happy with it nonetheless. <3

ALSO, in case you can't read the message over Infected's chest, is says 'WARNING!'. 

And so here's the concept of Virus!Sans, the left being his 'normal' state and the right is the 'Infected' stage that is always lingering within the his own code. Virus!Sans suffers from unexpected 'Flash Emerges' of his infected soul, the live codings, AKA Back Straps, show the consent, ever changing lines of those 1's and 0's sequences, a lot of them baring holes of 'emptiness' that--when a black hole passes through his core, his soul--causes a sudden image change for as long as that gap is passing through. It only lasts if only a second or three depending on how big that gap is before his image reverts back to his 'normal' state.

With his being changed to the core by the stolen number values, he has gained a few physical changes--a main change being his Back Straps. These act as extra limbs for him, aiding him extra hands specially when gathering codes from other multi-verses to rebuild his own timeline. With nothing in his home world, he has to go elsewhere to get the needed number values to make something in an empty void. Though the more of his powers he uses, the more coding within himself is devoured, leaving more holes within him. With his body eating itself away, he needs to keep renewing his coding supply so it would not only keep his body from eating itself out of existence, but to keep the number of sudden emerges of the virus inside at the very minimum. These 'attacks' in himself aren't pretty as each second Infected shows itself, it gives out a demented screech and/or cry with expected pain to himself being made. 

His Back Straps, when not in use, are small and act as loss clothing, though when active, they can stretch out and create hands at their ends at will. Not only are they able to lift his body from the ground, but they allow him to move quickly and climb to heights otherwise unreachable. In battle, he tends to stick to places off the ground where he feels safer, summoning Gaster Blasters at will to fire from different angles. Though to save coding, as creating Gaster Blasters takes up the most coding than any other attack, he has taken the habit to connect his Back Straps to the G. Blasters themselves. Giving them necks and stability, they are able to fire more than one blast usage before disappearing. When a G. Blaster is used up or fails upon being created, Virus!Sans tends to violently throw the used head away, either at his target or elsewhere where it would crash before breaking apart. Since V. Sans is in fact, a viruital being, 1/3 of his attacks may not work upon being summoned--in example 2 of 5 G. Blasters will not be able to load and be stuck 'buffering' before firing nothing at all. It being wasted coding in V. Sans' sockets which can get pretty aggravating. His missing codes can also lead V.Sans to glitching in repeat actions 2-3 times in a row--which can hinder him or aid him depending on the situation. In example, he can make an evading leap and end up glitching 2-3 times further than his normal jump would have landed him or instead of summoning 2 expected G. Blasters, 4-6 G. Blasters could be summoned instead which would be more than intended and an over-usage of code.

While V. Sans' Back Strap hands are made for rebuilding, Infected's hands are made for destroying, tearing valued numbers apart instead of collecting them up. He is wilder than V.Sans and has visible bodily defects which leads to his own image spazzing out in a static-like nature at random points which gives him more of the 'horror' manner than his normal state of being. His Infected image brings out more of his 'virus' nature and doing what his tangled, butchered coding implies he do--eat away at the mainframe and destroy the branching AU worlds. Just like what a high risk virus can do to a computer and shut it down completely. Seeing that V.Sans wants to rebuild his world and bring back his loved ones, he does not agree nor even like what he has become and has taken the habit to always wear his hood up to cover his shame. 

V.Sans can also relate to the sad and happy mask as his normal state of being never smiles and his Infected image always smiles. Even if V.Sans was able to manage a grin, the grinning side of his face would tear away into its infected image, seeming it takes his virus traits to even show any happiness in him. In reality, it makes him feel like a prisoner of his own body--but with the hope and progress of bring his world back, his desire to live remains.

I had a lot of fun really, drawing the 'breaking matter' of his being, it makes me think he would really enjoy the game Tetris cause of how you have to put everything together just right to complete the building shapes. It relates to his self-proclaimed job and just seems like something he'd play from time to time. xD
