Double Gear System

The Double Gear System (ダブルギアシステム) is a gameplay feature from Mega Man 11.

Story
Double Gear is a system developed by Dr. Wily when he was younger, but his research was stopped due to pushing robots beyond their limits being dangerous to their systems. In Mega Man 11 he finished its development, using it on his new attempt to conquer the world. Under Mega Man's request, Dr. Light reluctantly installed the prototype Double Gear system on Mega Man, giving him new abilities to use against Dr. Wily's robots. Although Mega Man gains increased speed and power, a side effect from overusing these gears is that it will overheat Mega Man, preventing him from using Double Gear again until after the cooldown has ended.

Speed Gear
Speed Gear (スピードギア) is a blue gear that increases the speed of robots. Gameplay-wise it slows down time when used by Mega Man, representing his increase in speed. The Speed Gear's effect is similar to the Time Slow's effect in Mega Man Powered Up, with the difference being that Mega Man now creates blue afterimages when moving around while the Speed Gear is activated.

Fuse Man and Bounce Man also have Speed Gears installed in them.

Power Gear
Power Gear (パワーギア) is a red gear that increases the power of robots. When used by Mega Man it allows him to shoot two Charge Shots together, with Mega Man moving aback a little due to its power. The Power Gear also increases the power of his Special Weapons.

Block Man, Blast Man, Torch Man, and Impact Man also have Power Gears installed in them.

Double Gear
Double Gear is only available when Mega Man is low on health, which can help him in a pinch. By simultaneously activating the Speed Gear and Power Gear, Mega Man can fire a devastating Final Charge Shot (ファイナルチャージショット) while time is slowed down. However, unlike the separated gears, it cannot be canceled when activated, and when its duration is over it will leave Mega Man severely weakened due to the overheat and becoming unable to fire both Charge Shots and activating the Double Gear System.

Trivia

 * The gears as they are shown in the intro references the colors of the Nintendo Switch's Joy-cons: Red and Blue.
 * The recoil effect that Mega Man experiences with the Charge Shot while the Power Gear is activated is similar to the Charge Shot in Mega Man IV.
 * Mega Man's ability to power-up special weapons through the Power Gear is similar to his successor's ability to power-up special weapons from most of the armors he receives through the Charge Shot.
