These characters from The Walking Dead never met, so they never got the chance to face off. How would these battles go?

Rick Grimes Vs Pope
Beta Vs Michael Mercer
Shane Walsh Vs Abraham Ford
Negan Smith Vs The Governor
Alpha Vs Maggie Rhee
Merle Dixon Vs Simon
Brandon Carver Vs Morgan Jones
Michonne Grimes Vs Leah Shaw
Andrea Harrison Vs Rosita Espinosa
Paul "Jesus" Rovia Vs Elijah

Just comment on the ones you have opinions on. Decide yourself if the fights are unarmed, with guns, blades, or other melee weapons (whether Merle has his bayonet or Negan has Lucille, for example), or if it's a scenario, etc. And feel free to add some of your own and discuss them/leave them for others to discuss.
