Boss: Yellow Devil[edit]
Stun weapons: Fire Storm
Yellow Devil is the first of four bosses in the Wily stages, and is also one of the easiest. Its appearance is that of a giant yellow blob with one eye.
On Easy, Yellow Devil stays in one spot and fires a green bullet at you. Remember that you can only attack him when his eye is open.
On Normal, Hard and in Old Style Yellow Devil moves from side to side of the arena splitting into 15 yellow balls. You need to memorize the pattern in order to succesfully survive this attack without getting hit. The pattern for each difficulties as follows:
- On Normal jump over 2nd, 4th, 6th, 8th, 12th and 15th ball
- On Hard jump over 2nd, 4th, 6th, 7th, 10th and 11th ball
- In Old Style jump over 1st, 3rd, 6th, 9th, 10th and 14th ball
After this attack Yellow Devil will shoot a green bullet out of his eye like on Easy. This is your chance to attack him. However, on Hard he'll shoot a laser beam out of his eye that will either move from the ceiling to the floor and vice versa. To dodge it you need to jump as soon as the beam is about to hit you when moving from the ground or by moving close to Yellow Devil if it moves from the ceiling.
Yellow Devil can also slap you if you get too close to him. You have to quickly move away otherwise you'll take a great damage.
Yellow Devil's weakness is Fire Storm, which will destroy him in 7 hits.
