Chrono Trigger. Final boss. And lots and lots of Frog Squashes.

Not the cheapest victory I made, but still... kinda recent. So...

My cheapest victory? Easy. FFX-2 against Paragon. I had Rikku as Lady Luck and bribed him a mere 11,003 gil to leave. Then I got my butt handed to me on a plate by Trema.

My second cheapest would be Tekken 5 and getting Devil Jin after just thirty wins. It took all of my friends who have a copy of the game around two hundred, unless they played the mini game. It's not technically a win, but still..

Disgaea.

Apparently, if you throw the Overlord of the other dimension onto one of those little 1x1 squares on the side of the level, she won't do anything. Not even heal herself.

I did that, then I got Laharl and nine other guys who knew Braveheart, and would just have him wail on her while she sat there and did nothing.

It was fun adding a level 2000 character to a roster of lvl. 500 and less.

Lets make a FF7 analogy, since the game in question is FF7.

(Safer Sephiroth) Team of Level 70 characters (Cloud (by default, how I wished to kick him off), Red XIII, Yuffie) Maxed out Knights of the Round was equpied to my super stylish Yuffie. Yuffie casts Haste on party, Cloud casts Wall, Red XIII casts Regen. Sephy-chan stares at my group. Yuffie uses KotR, Cloud Mimes, Red XIII Mimes, Yuffie Mimes, Sephy-chan stares at me and gets anally probed by Cloud...

Ok, watching one of the guys play SSBM, he's playing Samus, and it's agenst a Lv. 9 Yoshi. For the last three lives, Yoshi suicides.
