Distance between them - 10 km.
Battlefield: Universe 616, near one of destroyed (by Annihilus) Skrull planets They can fight only in space (none of them wants to bring this fight to the planet)
Both in character. Firelord belives that Black Adam is one of Annihilus' Centurions that still lives in 616.
No prep. No knowledge about enemy.
Point of this thread: This is test for Adam's durability for high level energy projection and Firelord's durabiltiy to blunt force.
