I'll preface this by saying that I realize there is a similar battle thread out there. However I do not like the scenario or lack there of in that thread. So I would like to hear peoples opinions based on this scenario:
Fighters: Peak strength. No Limits. All movie attacks are acceptable.
Setting: On a perfectly circular island 100km in diameter. It is a forest island with very old trees that all stand between 70-100m high and cover the entire island save the center. In the center of the island exists an indestructible volcano. No attack can destroy the volcano. The volcano magma is capable of instantly burning anything it touches to cinders. Every other part of the island is still destructible.
Starting positions: Fighters form a triangle all equally far apart from each other at the edge of the island.
