Metal Bros.

The Metal Bros., Metal Mario and Metal Luigi, are mini-bosses of Classic mode in Super Smash Flash 2. They are fought in fought in level 9 of the mode for Hard difficulty or higher as alternative mini-bosses of the regular random metal characters and, as such, are the last foes before himself.

Overview
The battle against the Metal Bros. takes place on Meta Crystal and, as stated above, is only accessible if the game mode is played on Hard or Intense difficulty. To complete the level and move onto Master Hand, the player must defeat Metal Mario and Metal Luigi. They are not unique characters, but rather permanently metal versions of and. They each have one stock and damage ratios of 1.2, meaning their attacks deal 20% more damage than normal. When playing on Hard difficulty, their CPU levels are set to 5, whereas on Insane, they are set to 7.

The Metal Bros. can be very difficult to fight due to their nature as metal teammates, as the player must fight two simultaneous opponents with passive heavy armor. The small size of Meta Crystal can also make them difficult to evade. However, their high gravity and falling speeds also make it difficult for them to recover once launched off-stage, allowing them to be KO'd rather easily with attacks such as throws that bypass heavy armor.
