Most favorite (in descending order of favoritism):
GT Aiga (He's all over the place)
Delta (this guy's hardcore lol)
Gwyn w/ Regalia Genesis (Big Bang is not as good imo)
Free's God launch (vein mode, together with popping veins and bulging eyes, he looks downright scary)
Favs from every series:
GT: Aiga's launch (come on, this one's like, pure awesomeness)
Cho-Z: Errrr...these weren't anything too special for me, but Phi's first launch was kinda neat.
God: Red Eye's first Axe Shoot looked pretty badass (even tho I still can't get how he never trips when he does it).
Classic Burst: Valt's High Jump Shoot was amazing, and it gets Bonus points for being the first midair launch in all of Burst.
I'll definitely put something here soon.
Probably.
Maybe?
Naaaaah.
Original Burst: Valt's really high jumping shoot.
God: Shu when he was battling Lui the second time around where his scar glows
Cho-Z: Phi with his flaming launch
GT: Delta's butterfly kick launch ftw, or Aiga with his damn backflips
Sparking: Lane's "throw launcher high in the air then Naruto runs to catch it then shoot" launch lul
Burst: Valt's runaway shoot
God: Shu's launch
Cho-z: Aiga's launch with cho-z achilles
Gt: aiga's and delta's launch
(I know I was not supposed to but how bout I do it anyway)
Sparking: Lane's last launch form
DB: Bell's
