This AU is called Pushed too Far

Poppy has been driven mad with the constant comments and suggestions that they're just like Cobs

So they decided If you so desperately want a villain

I'll give you one

This is their fault, that's what makes them more scarier than Cobs, because this could've been prevented

Unfortunately there was times where Bot was also included (like the fight they had)

They went rouge and no-one could find them for weeks, a lot of people were worried about them but a good portion were like "Good riddance, we don't have to deal with them anymore"

That was until they suddenly came back but they weren't coming back to talk. They had other motives. Their psyche is snapped. They had found the old switch blade Cobs used. OJ, Fan and Test Tube tried to talk to them but they weren't helping

Poppy actually managed to kill someone during an outburst. And it was the person most at risk. Balloon. Paper and Fan were also victims. Everyone else was mild to badly injured and went into hiding

Bot is determined to try and help them because they believe they can be helped but Test Tube is very much adamant that they stay away from them for their own safety
