Legato was recruited by Knives after the July incident
to make Vash's life a living hell, though the
nightmare
doesn't really begin until about midway through the
series. From that point on, this man continues to weave
a
living nightmare for Vash, not only on his own but
also through the gang of eleven superpowered killers
who are under
his command: the Gung-Ho Guns.
Legato himself possesses dark power: the ability to
control people's bodies against their will. His
favorite bit of poetic justice is to make gangs of
people who oppose him shoot each other, and this
special power
is what finally forces Vash to cross
the line he promised himself he'd never cross. By
controlling some villagers
and pointing their guns
at Meryl and Milly, he forced Vash into a choice
between two unacceptable options: either
allow the
girls to die, or take the only possible action to
save them...and kill him. Legato's telekinetic powers
come from the fact that he has Vash's left arm. When Knives shot it off, it was attached to Legato. This is why Legato can
control other people's bodies (originally one of Vash's and Knives' powers) and can activate Vash's angel arm the same way
Knives did in July.
