Staff Rocket Boost

Staff Rocket Boost, also known simply as Rocket Boost, is 's up special move in Super Smash Flash 2.

Overview
When performed, Krystal takes a small pause before boosting herself upwards with her staff. Opponents hit at the very start of the move are meteor smashed, and opponents hit as she rises are dealt high electric damage with strong upward knockback. The move can be used for recovering, but both its vertical and horizontal distance are quite poor, and it leaves Krystal helpless afterward.

Origin
The Staff Rocket Boost is the second Staff Upgrade that Fox obtains for Krystal's Staff in Star Fox Adventures. It grants Fox the ability to boost himself straight upwards with Krystal's Staff to reach high ledges. However, this can only be used in unison with Rocket Boost Pads, which are located on the ground in predetermined places around Sauria. Like most Staff Upgrades, using the Rocket Boost also depletes Fox's Staff Energy Meter, which can be refilled by collecting Staff Energy Gems, usually dropped by Magic Plants.

Trivia
