Super Milk Time
Demon Sword: Alaindelon
Hmm gotta be Super Milk Time . Both powerful and badass looking , Oga is the king ...
super milkey time! seriously what other techniqe is there?
I nominate "Father Switch"
Where all he did was try harder.
Jabberwok: "You're not making any sense here!"
Lamia: "That's just ridiculous"
I would go with Super Milk Time.
It grants Oga with a great power boost, especially if used correctle.
My nomination: Father Switch aka Trying Harder.
My reason: When you're able to grasp the fundamental of shounen mystic source of superpower, you get yourself best technique. Traditionally, powerful basic technique like this raise you up after defeats against sub-boss level opponents and drive you to glorious win against final boss (for a certain period of time, until you have to try harder to try hard.)
I Nominate: Furuichi's Giga Dean Technique .
Reason: What can you do against shitload of electricity, mixed with water <3 it's tough tho i want to nominate Oga's "Bury Them in the Wall or Bury Them Into Whatever Object I Can Plant Them In" Technique also ;S
