Who is Jonathan Martinez from Midnighters #3: Blue Noon and what is their importance?

Jonathan Martinez is an acrobat. During the blue hour his gravity is reduced, something that allows him to increase the distance of his jumps to create a flying effect. He loves the freedom and very much likes regular time as a result. Jonathan shares the effect of reduced gravity with anything he holds on to, including people. His gravity-less acrobatics, however, only function during blue time.
