Awesome, I got the Z-Saber with my Gold Max Armor! Hey Zero, check this sh...i... oh.
(BAD END)
The Ultimate Armor/Black Zero in X5 and in X8 are the exceptions in the punished for overpowered mode rule, namely because everyone (who isn't accustomed to smack X5 a new one) would [sonic slicer] their heads off if they had to fight Maverick Zero without spamming the ever-loving crap out of Nova Strike (even if he has the most retarded boss programming in the series.) In X8, it was just to give the player something to mess around with for future playthroughs, which became the norm in Z3 and Z4 with Ultimate Mode. Z1 also had Ultimate Mode, but you had to bust your ass off before you even hoped to look at it.
