It’s the Energy Tank! Otherwise known as E-Tank, this is a staple item of the Mega Man series that restored all of your health.
It may look small, but it sure packs a punch!
When you get one of these, you are healed all the way back down to 0%, no matter what you may already be at. However, it’s not instant, and you become vulnerable the moment you grab it.
You’ll waste a second holding it up.
Though this may be the strongest of the healing items, there is one significant other one I should mention…
Of course! The Heart Container!
The Heart Container heals up to 100%. Be sure to grab these if you see them in the middle of battle, as they can turn the tide very quickly.
