An active volcano is in the distance but won't erupt during the battle. Some lava is slowly flowing out but will only effect things if venturing towards the volcano. Most of the ground is cooled lava and other rock, few patches here and there still on fire. Mech eating fire rabbits do exist here but thankfully are hibernating.

Story: 
Some guy in a mech is probably wanting to kill some guy in armor who has heat related powers and stuff. Since his mech is good at heat resistance he's all like, "mwahahahaha! I can win now! This volcano is nothing!"
