Mutation: Rick can control everything that pertains to kinetic energy, movement and speed. As such, he can absorb kinetic energy from a punch, for example, and use it as self-healing or to boost his own physical energy. He can convert any type of energy into kinetic energy. He can add or steal momentum to any object or person (he prefers to do it on vehicles). He can do everything 10 times faster than any normal human. When running, Rick can go as fast as 375 mph. If he concentrates hard enough, he can vibrate through objects such as walls (only for a short period of time, even then, it's always painful). Finally, to top it all off, Rick can transform his body's biochemistry to that of any material (gaseous, liquid or solid) that he has touched. However, all this power comes at a great cost: his body is unstable and his cells are deteriorating. He has less than a year to live. Also, he needs to eat and drink as much as 10 persons to fuel his powers. If prevented from eating the required amount, he may die.

Skills: Rick knows martial arts, chemisty, first aid and has learned some techniques to close his mind to mental intrusion. He is a professional race driver.

Costume: Full bodysuit black and dark blue, with a yellow sun on his chest. He also wears a utility belt with several pouches. His shoes are hardened, to resist the speed at which he runs. To complete the entire costume, he also wears dark blue gloves. He wears polarized lenses, to prevent sudden light attacks.

History: Experiment IV, or Rick Quicksilver, as he likes to call himself, is actually a clone of Esteban Ricardo De Azogue. He was born in the future then somehow managed to escape. How he did it is still unknown, even by him. He is one of the rare experiments that have more or less succeeded (he is considered "failed" because he wasn't identical to the original and wasn't as fast as the original). It is believed that just like the others, his longevity is only of a few years. He already outlived most of the clones...
