Chain Blast

"Shoot Blast Man's very own sticky bombs! Connect up to four bombs via the red line for bigger blasts. Try it with the Power Gear active to unleash massive bombs!"

- Weapon description

Chain Blast is Blast Man's Special Weapon in Mega Man 11. After obtaining it, Mega Man is able to shoot bombs that float across the screen, sticking to enemies along the way. Multiple bombs can be chained together and detonated at once to create bigger explosions. Mega Man can either blow up the explosives instantly or wait until the explosives detonate on their own.

While the Power Gear is in effect, Mega Man is able to create much larger bombs than usual, allowing for bigger explosions.

Like all of the special weapons in the game, Chain Blast gives Mega Man new Head Gear and Arm Gear that alters his physical appearance when equipped, rather than just being a color swap. In this case, the Head Gear is a new helmet that resembles Blast Man's, but with smaller spikes than the ones on Blast Man's helmet. The Arm Gear mostly keeps Mega Man's hand intact, but slightly changes the appearance of his buster arm and adds a protective cover over his hand.

Trivia

 * Chain Blast works similarly to Remote Mine as Mega Man can manually detonate the explosives.
 * It's also similar to Danger Wrap in that it latches onto enemies before exploding, just as Danger Wrap encases enemies in a bubble along with a bomb inside the bubble.
