How many Batman & Nightwing's does it take to...?
Here's the scenario:
Batman and Nightwing are given Multiple Man's power of self replication and prep. How many Dynamic Duos would it take to defeat each stage of the following gauntlet:
1) Luke Cage & Iron Fist
2) Wolverine & Sabertooth
3) Cyclops & Havok (Classic Havok)
4) Hawk & Dove
5) Multiple Man & Strong Guy
6) Dr. Light & Cyborg
7) Cable (classic) & Rachel Summers
8) Dr. Doom & Mandarin
9) Atom Smasher & Red Tornado
10) Hulk & She Hulk
11) Grundy & Live Wire
12) Black Bolt & Fantastic 4
13) The Four Horsmen of Apocalypse (Sinister, Sugar Man, Abyss, Mikhail)
14) Thor & Beta Ray Bill
15) Black Adam & Captain Marvel
16) Superman & SuperGirl
17) Silver Surfer & Firelord
18) Hal Jordan & Alan Scott
19) Thanos & Apocalypse
20) Darkseid & Kalabak
Prep rules are as follows:
Batman and Nightwing get full use of all tech ever depicted at their disposal on panel after round 5. Prior to round 5 it's only standard tech(no boomtubes/motherboxes).
They get an hour of prep for the number of each round plus the time from the previous round (so in round 2 they'd have 3 hours of prep; 1 hour for round 1 and 2 hours for round 2, in round 3 they'd have 6 hours of prep; 1hr/rd 1 + 2hr/rd 2 + 3hr/rd 3, etc).
Their opponents get no prep.
State how many Duos it would take to clear each round and also how they'd achieve victory (if possible).
