Maverick Parts

After defeating mavericks with a level of at least 8, Alia will ask if you want Life+ or Weapon Energy+. That + is a part that can be equipped, and the part you get depends both on the Maverick defeated, and the Life/Energy choice. 
 Many of these are currently documented at the Mega Man Home Page - https://mmhp.net/GameHints/MMX5.html#Items 
 All Stages Route Parts 
 
 Bat - Life
 
 The Anti-Virus options are not useful in a speedrun, so take the HP 
 
 
 Mattrex - Life
 
 Again, neither part is particularly useful. 
 You should be here early enough there is no part anyway 
 
 
 Grizzly - Energy (Hyper Dash) 
 Whale - Life
 
 Weapon+ grants the Energy Saver 
 
 
 Axle Rose - Energy (Z-Saber+) 
 Izzy Firefly - Life
 
 For the HP. Energy gives shot eraser for Zero 
 
 
 Squid
 
  Life if you play the last stages as X 
 Energy grants Saber Extend for Zero but is not available until the final stages 
 
 
 Pegasus - Life
 
 this part will never be built if you do it next to last, but this creates the Jumper part 
 
 
 
 Time Until Part is Crafted 
 After selecting a part, it takes 2 in-game-hours (so 2 selected stages) to be created. This Includes Dynamo encounters and Zero/Sigma stages. This is why the optimal route  for All Stages defeats Grizzly for the Hyper Dasher second, then uses Dynamo and the autoscrolling Duff McWhalen to have the Dashing part crafted. 
 What controls a Maverick's Level? 
 
 Rank increases a maverick level. The route assumes GA before fighting Grizzly 
 Hours left until impact
 
 Does not affect Level after the colony is destroyed (such as by using The Manip immediately) 
 The route depends on hours passing to allow mavericks to gain levels. Do not fire the enigma cannon until after fighting Grizzly for the Hyper Dasher.
