Buff Frog, real name Yvgeny Bulgolyubov, is a former member of Ludo's army who spied on Star Butterfly in addition to taking part in the battles against her and Marco to steal the wand. At the end of season 1 he reformed his ways, becoming an ally to Star and Marco. As of season 2, he raises a family of twelve adopted tadpoles and works with Boo Fly. As of season 4, he has left Mewni in fear that there will never be an understanding between his generation of monsters and Mewmans, though he does have hope for the newer generation.
Range:Standard Melee, Tens of Meters with his tongue, High Multiversal with dimensional scissors
Intelligence:Above Average (Was the only one in Ludo's army able to see through Toffee's deception, is usually able to formulate an enemies weakness and knows when to strike)
Dimensional Scissors: Dimensional scissors are used for traveling between dimensions. By cutting anywhere in the air with the desired dimension to travel to in mind, the scissors create a portal. The portal itself usually reflects the designated dimension, like the portal to the Amethyst Arcade being pixelated and the portal to the Scum Bucket looking like blue waves. After someone passes through the portal, the portal either closes by itself or it can manually be closed by someone. The scissors can also be used as weapons, as demonstrated by Hekapoo. As revealed in "Deep Dive" and "Ludo, Where Art Thou?", if a scissors user does not have a specific destination in mind when using them, the portal that they open leads to a dead end.
Standard Tactics: Buff Frog's method of fighting is carefully surveilling the enemy and only attacking when they seem to be at a state of weakness, there is a flaw in this plan though as he can often misinterpret or miscalculate the state of their weakness, like how he thought Star was defenseless on Earth because he didn't take Marco and her own fighting power into consideration.
