Skull Man uses a complex attack pattern that can fool a rookie player easily. He starts the battle by jumping and using his skull shield, he cannot be harmed by using the shield, when he turns the sheild off he will dash at you and stop at the very spot you are standing. Time your jump and jump over him. Now here comes the tricky part so bear with me readers. Skull Man will now fire 6 shots (three at a time) at you. To avoid the first three jump in the air which will make his first shot miss you, let the second shot come right at you and jump over it which will cause his third shot to miss as well. Do the opposite the second three shots let the first shot come at you jump over it and his second shot will go up in the air and miss you finally let his third shot come at you and jump over it now nail him with the mega buster or his weakness. This strategy can take a while to master so just be patient.
