Flight Formation sees the Teams arrange themselves in a three-man tower, with the Fly Type character keeping them aloft. Pressing (GCN)/ (Xbox)/ (PS2) sees the leader punt one of their allies forwards like they're kicking a football, (somehow) conferring upon them a crackling shield which sends them homing in against enemies.
The move's damage and effectiveness varies depending on the flight character's level, from just stunning an Eggman robot to exploding a whole set of them one after the other. Either way, it will always knock the opponent out of the sky, and as such is often the only way to down an otherwise out of range flying enemy. A more detailed description of each effectiveness is as follows:
- Level 0: The attack can only hit one enemy at a time, and can only stun the enemy without causing damage. The thrown teammate gets hurt instead.
- Level 1: Causes one point of damage to the target and stuns them for longer, possibly hitting two targets with one shot.
- Level 2: The attack now has a slight chance of destroying the target, and can hit multiple targets. If not, the stun time inflicted on the enemy is even longer.
- Level 3: The attack can very easily wipe out hordes of enemies within shooting range, making it one of the most powerful attacks in the game. The move also acts like a magnet that can pick up Rings.
Since a Fly character has two friends underneath him/her, this move can be used twice in quick succession. The move can also be used to knock down flying cages and to hit Target Switches.
