It's time for the Big Two's Most Retconned Beings/Races to clash!
1. Pre-Retcon Beyonder vs. Primal Monitor. "Original" forms (i.e. the infinite sapient whiteness in which the multiverse is a mere speck.
Presentation only (unless both have on-panel feats, which I doubt the Monitor has, but I know the Beyonder does). Are they presented as equal concepts?
2. Post-Retcon Beyonders vs Final Crisis Monitors. Race vs Race. Unsure of any direct feats. Who wins in standard Rumbles settings?
3. Current state in main canon comics. Who is doing better these days?
