Vinnie "Mass" Rossi

Vinnie Rossi is also known as Mass was a two-bit extortionist who was strong enough to punch through brick. He rhymes most of what he says after his mom always said be unique. He was hired by Paine to enter a wrestling battle royal to win the WWC title belt so Paine can use the belt's diamonds for his new laser. Paine only went to Rossi after Flesh injured leg because Paine overworked him. When Spydah suggested him, Paine implied that he was dumber than Flesh.

When Paine approached Rossi about his offer, Rossi said he'd think about it but Paine used his pain touch on him to force him to do it. In the battle royal, Rossi was one of only two participants left with the other being King. Despite his heelish actions, Rossi was tossed out of the ring by King losing the match. He was distracted by the attractive Lioness who was cheering for King.

At the docks, Vinnie tried to apologize to Paine, but when he told him that he was in love, Paine angrily shoved Rossi in a mining car. Concrete was dumped on top of Rossi as Paine dropped him into the sea. Little did Paine know, there was radioactive waste near where Rossi had sunk to. The waste mutated Rossi into a giant mass of concrete with iron pipes sticking out of his shoulders.

When Paine and Flesh went back to steal the belt, the now mutated Rossi followed them. Inside the vault where the belt was kept, Rossi, now wanting to be called Vinnie "The Mass" Rossi, interrupted a confrontation between Paine and Flesh and the Alpha Teens. He proved to be invulnerable to Paine's powers and Axel's Jo-Lan and stronger than Flesh and King. Mass takes the title belt and Lioness and escapes.

With the belt Mass intended to retire and then make Lioness his wife. When he went to see his momma, Paine and Flesh came to get the belt back. Paine fired on an unharmed Mass who was protecting his momma and Lioness. Paine threw his mother on a gurney and he chased after her losing the belt in the process. His mother saved, Mass asks Lioness to marry him. Though while she appreciated him sticking up for her from his mother's judgment and she thought his care with a baby he rescued was neat. All the same, Lioness told him she wasn't attracted to him due to his appearance.

Deeply hurt and greatly angered, Mass turned on Lioness and in a fit of rage almost leveled the entire hospital. His attempt was halted by King, so Mass sought a rematch between the two. King was nearly defeated until Axel found some sleeping gas and threw it in Mass' mouth. Mass was knocked out and fell several stories down. Still sleeping, Mass was carted off to jail on a gurney.

Sometime later during him being transferred to another prison, Mass was rescued by Spydah and Flesh. Paine needed him for an underground assignment, where his rock body won't be affected by the intense heat that regular humans can't handle. Mass initially refused, but with his mother captured by Paine, he reluctantly agreed. Flesh unintentionally told Mass that Paine was holding his mother next to their location.

He breaks into Paine's lair and rescues his momma. He tell Lioness, who she and her team were there to stop Paine, that they weren't meant to last, completely over his feelings for her. Mass' momma tells him to get Paine. After reaching Paine, Paine tries to make with deal with him to still help him. Mass again objects but his momma says they can rule Landmark City. He likes the sound of "Mayor Momma Rossi" so he decided to still help Paine.

He was sent to take a bomb to a lava crater so he can blow it up and flood Landmark City with lava. Axel stopped him before he could do so and threw the bomb in a hole they were climbing out of. Axel made it out before the bomb went off, but Mass was caught in the explosion with some Lava from the crater engulfing him. The Mass is now fused with the lava, but he survived. All he was concerned about was finding his momma.

Even though he's a villain, Mass seemingly has some compassion and caring for others. There is no question that Mass is threatening, overly aggressive and easily angered, but he has shown how gentle he can be around women (his Momma and Lioness) and children (the baby he helped saved).

Mass full first name is also into question. Paine calls him Vincent and his Momma calls him Vincenzo.
