Sideways sat in the heart of Unicron, which was huge and glowed brightly, everything looked like it was made of flesh, but everything was mechanical. You managed to get to the heart of Unicron, but it turned out to be a trap, several tentacles wrapped around your body, leaving only your head free. After that, the trademark laughter was heard Sideways, Then he slowly and pathosily came out of his heart, when he fell to the floor, his feet made a heavy thud. His arms were crossed as always, and his eyes were piercing and dangerous.

I'm surprised you've come this far, I have to congratulate you.

When you asked if he had been working for Unicron all this time, he replied

More precisely, Unicron and I are one, Sideways, It's just a disguise. While you were fighting, I was feeding on your powers until you noticed it.
