Description
The initial kick of Jackknife Maximum.
Executed by charging downward, then pressing upward and kick, Dee Jay leaps up and forward into the air while delivering a slashing kick(s). How far the move travels and how many kicks are used (and thus, how much recovery time the move requires) is determined by the kick button used: light kick has the least startup time, travels the least and delivers only one kick; heavy kick has the longest startup time, travels the most and delivers three kicks; and medium kick balances in-between.
The EX Special version introduced in Super Street Fighter IV delivers 5 kicks, and travels the furthest into the air with the least startup time.
