LEFTTALE SANS BY MY BROTHER TWISTEDMONSTER1234
(You don't need or have to read it)
Frisk/Player found LEFTTALE SANS or Left sans. And this is a fight.
I call him Lefttale sans, but it's faster to put Left sans so.
Left sans is a kidnaped monster who was experimented on by Left Gaster, Throw the years of the experiment's sans jacket and clothes started to tare.
Left sans was told to smile the entire time being experimented on by Left Gaster.
I believe his tiers changed cuz in the original artwork by the creator (My brother), he had Black and Blue tier's. so it may get updated IDK
Left sans did end up, killing Left Gaster. Left Gaster fused with Left Sans memory but now he has a scary on his face.
Rain is Left sans or LEFTTALE SANS main and most powerful weapon, as it's able to repeat any kind of attack that Left sans seen. this Button doesn't need you to remember the attack, but it's stronger if u can (Example: LEFTTALE SANS has photographic memory)
LEFTTALE SANS or Left sans can only be found in a genocide route, and is left behind to be forgotten in other route. I'm not joking.
(My thoughts on the sans, I think I putted what I know about this sans, I can't see why he's called LEFTTALE sans. I think it's because he has no good ending and regardless he will get left behind. I do remember Gaster will help LEFTTALE sans to fight, by defending him... yeah that's all, this au was made by my brother and yeah. hope u enjoy reading)
