Power Suit Samus (sometimes known as Crystal Flash) is Zero Suit Samus' Final Smash. She radiates energy, dragging in items and enemies towards her while damaging anyone close enough, then somehow regains her suit. If enemies are caught, they are given 25-26% damage each in the spin and an extra 10% right when she regains her suit. It is recommended to wait until the Final Smash is over, and then when Samus gets her ability to move, strike her before she can dodge an incoming attack. The attack, if it pulls the enemy in, hits with high knockback, but it is hard to hit someone correctly due to incredibly short range, and it's hard to catch people with.
Speculation suggests that it is similar to the "Crystal Flash" technique from Super Metroid. In Super Metroid, the Crystal Flash was an advanced technique that would refill all of Samus' Energy Tanks, at the cost of Missiles, Super Missiles, and Power Bombs. During the Crystal Flash, Samus could be seen in an orb of light without her suit.
Zero Suit Samus's Final Smash. Samus loses her Power Suit when she fires the Zero Laser, but she can restore it--that is, she can return from her Zero Suit form to her familiar armored form. That being said, Zero Suit Samus is very quick with great reach, so there are tactical reasons to fight as is. If that's your preference, don't pick up any Smash Balls.
