The batsuit has taken on numerous forms over the years. However, when extra power is required, Batman has a special suit to take on his foes. The armor suit technically has been seen three times over the years in various forms.
The most popular being in The Dark Knight Returns where he uses it to beat up Superman. But also, it's been used in a more mechanical form against Bane and the Court of Owls. This suit not only gives me better defense, but more attack power. More than enough to fight foes who outclass him in the strength department.
I you see Batman in this suit of armor? You're in trouble.
