How Good is Butterfree in Pokémon Yellow? | Solo Run

Today, we will be evaluating Butterfree and seeing how well it does in the game of Pokémon Yellow.

Rules:
Every Pokémon has Max Stats. This is to evaluate them at their absolute best.
I give myself a flying Pokémon so that I can fly right after beating Surge. (saves time)
I give myself a Poke Flute so that I can skip Rock Tunnel (saves time)
I use rare candies to gather levels where needed. (saves time)
I give myself infinite healing items. (saves time)
I am only evaluating how Pokémon perform in the Pokémon League challenge. (8 gyms, elite 4, & champion) sometimes more depending on the game.

No Items in battle.
Level cap set to level of enemy ace.
Only 13 major Pokémon League Battles counted.
