You were an overlord like Alastor, you were powerful so he respects you and you two grew to be friendly rivals

One day you invited Alastor to your base

When he got there, it was empty except for a few vines on the floor.

He stepped on one and.. The vines started wrapping around him, obviously he tried getting out but to no use, he dropped his staff/microphone thing. Anyway the vines left him hanging, his was hands over his head, wrapped around his legs and hands, and his waist.

You suddenly appear with a smirk
