Alias - Melissa Gold, El Cascavel
Appearances - 33 (26 in Thunderbolts, 7 in Sensational Songbird)
Before re-joining the Thunderbolts, Melissa protected the Washington DC area, and later chased Killer Shrike when the villain stole a radioactive isotope. Despite being aided by the Avenger Hawkeye, Shrike escaped although he had lost when he had stolen, and the two heroes went to lunch. Once there Melissa was shocked to learn that the Avengers were ready to accept her as a member, but in the end didn't give a definitive yes or no to joining the team. Returning home, she received a cry for help from a young runaway she had met, and flew to help but was ultimately too late to rescue her due to interference from Killer Shrike and Taskmaster.
A few weeks later, with the help of Abner Jenkins Melissa masqueraded as the villainess El Cascavel to infiltrate the Serpent Society and later participated in a raid on a downed Helicarrier. After slipping inside Melissa quickly defeated Anaconda, Black Racer and Coachwhip before engaging Death Adder. After a tense battle, the pair were forced into a stalemate, with Death Adder dosing Melissa with a deadly venom seconds before he was knocked out. After recovering Melissa fell into a depression about loosing Lannie, and was mocked by Moonstone (although its probable this was just her dissatisfied subconsciosus) who forced her out of her apartment to buy flowers for Diamondback's funeral where she was ambushed by Lady Hellebore. Melissa later caught up with Taskmaster, and overpowered him, with the master mercenary finaly revealing where Lanie was being held.
Sometime Melissa was incarcerated as part of her investigation into Black Oak prison. During a meeting she told Abe to visit home, a message that was echoed by former Thunderbolt Hawkeye. Later Melissa would engage Joystick in a brutal fight that ended with her being taken to the Advanced Measures Wing. Waking up in the Advanced Measures Wing, Melissa was surprised to find that the Warden was pleased with her actions, and put the other meta criminals under her command. She later took fellow prisoner Nightshade for Interrogation but secretly was aiming to escape from the Black Oak and submit her testimony to the CSA. The two escapees stopped at the infirmary, to get Nightshade medical help, but were discovered by Superia. Melissa would send Nightshade and Rock Python away before fighting one on one with Superia. The pair were on an even footing until Superia destroyed the wall of the prison, where she was eventually defeated by the Thunderbolts. Melissa made a promised to Nightshade to help her get through Medical School to become a legitimate doctor, if she joined the Thunderbolt.
Melissa later worked with Rock Python to thin members of King Cycle's gang, and was the first of the team to recognise Thor when he intervened in their pursuit. Melissa would later fight Thor after he attacked the Thunderbolts, and despite her best efforts was defeated. She would later shield the entire team when the Thermal Man tried to destroy them. After recovering from the blow the Thunderbolts defeated their firing squads and split up to stop the Thermal Man, with Songbird, Nightshade and Rock Python going to Cheer Chadwick's lair in an attempt to stop the neural link between woman and machine. Songbird led the team into the Hesperus Chadwick Neurology Centre, and while she recognised a name on the directory, before she, Nightshade and Rock Python confronted Cheer Chadwick. Melissa initially fought Hoopsnake, and later subdued Ingot by knocking her into a vacant indoctrination booth. She later worked with Rock Python to take down Cheer Chadwick while she held Nightshade hostage.
Melissa was present at the Denver-Miami game, and fought alongside the NFL Super Pro to thwat the would be assassins, despite his initial attack on her. She later took great glee in knocking the Super Pro out when it was revealed that he had hired the assassins to boost his ratings.
Songbird worked alongside Rock Python to stall the G.L.O.B in the mines while Nightshade and MACH VI created a catalyst that would destroy it. The pair of them were almost killed by the creature, before being rescued by the Absorbing Man. Melissa fought against Scourge, with the villain almost killing her before she was rescued by the Absorbing Man. Melissa later blocked an attack from Scourge, but was later incapacitated by Titania.
Melissa was one of the Thunderbolts having brunch when Joystick was detected. After being shot down she fought Joystick, and was later blinded when her foe flicked salt in her eyes. Recovering Joystick used her batons to deafen Melissa, who was later taken to hospital after the battle. Melissa watched the second battle between the Thunderbolts and the Agents of Vengeance, before being read into the Beetle Protocol due to Abe's abduction. Entering the former Thunderbolts Mountain Complex, Melissa watched as Valerie Cooper donned the Beetle Mk3 Armour to fight the Red Hulk. Melissa later fought Joystick and Boomerang, easily defeating them both before being incapacitated by Scourge.
Songbird would later lead a reduced team to deal with the threat of the Masked Marauder in Denver. After a tense battle they defeated him, only to see a stone sword shoot across the sky. Melissa later joined the team on the hunt for the sword, and infiltrated Castle Zemo to rescue Citizen V only to be attacked by Crossbones who utilised a sonic null field to prevent her from using her powers. Despite this Melissa fought back, and with the aid of Citizen V defeated the thug. Later to infiltrate the quarantine cells to rescue the imprisoned medical staff, Songbird and Citizen V controlled Crossbones like a puppet although it didn't fool the prison guard Yuki-Onna. Despite this the frost demon agreed to help the Thunderbolts deal with the DOA's plan to activate the Sword of Xibulba. Melissa rejoined the other Thunderbolts and attacked the Blood Brother and the Sword of Xibalba.
Melissa and Abe took a trip to Sienna, Italy over the Valentines weekend. While in the plaza on the last day of their getaway the pair of Thunderbolts were ambushed by the Great Game. After a skirmish with Birdman and Lady Hellebore Abe proposed to Melissa, something she accepted before using the diamonds on the ring to defeat the final assassin Killshot.
