Galick Gun (LV1)
Instead of a single multi-hitting energy blast, Vegeta fires out a volley of multiple single-hitting energy waves. The aerial version fires the waves vertically down. As with the Kamehameha you're able to cancel the LV1 version into the LV2, granted you have the required amount of power bar available.
Bakuhatsuha (LV1)
Vegeta jumps back while creating a large explosion in front of him. When used in the air he immediatly creates the explosion on the ground without first jumping backwards. Fun and recommended to use after a Rising Knee Arrow.
Super Galick Gun (LV2)
Souped-up version that lets Vegeta fire 20 waves rather than 5. The aerial version still fires vertically down.
Bakuhatsuha (LV2)
Souped-up version that creates two explosions in a row, one in front of the other.
Final Flash (LV3)
Vegeta slides backwards out of the screen and then fires his Final Flash into the screen, doing major damage if it connects. With proper screen-placement and timing you can combo into this after ground-bouncing the opponent.
Bakuhatsuha (LV3)
Three explosions in a row! A brutal attack, well-suited for Vegeta. Does massive damage if you can connect with all three explosions.
Galactic Gunfire (LV3)
Vegeta's Galactic Gunfire starts out with a launching kick (which you can combo into, recommended to cancel it off a Rising Knee Arrow). When it hits, the opponent is launched into the air. Vegeta teleports above them, stomps them back down and then starts charging up energy. During this part, two icons will appear onscreen beside Vegeta indicating that the player can mash buttons to speed up the energy charging; doing so will result in more Ki Blasts being fired down. Without the button mashing, the move isn't very damaging, so mash like you mean it!
