The verdict: Doom wins most nights

Fight rules: both fighters at their peak, no preparation, no allies, only their own powers and personal gear. A win is a knockout, a restraint they can't escape, or a forced surrender. The percentages are fan estimates, not official information.

Doom's edge

He has killed her before: Doom struck her down when she charged him (Avengers: The Children's Crusade #8, 2012).

Cassie Lang's edge

Pym particles let her shrink or grow to giant size with matching strength, and she trained for years with the Young Avengers.
