Background Information[]
At some point in her life, Iguana would gain her abilities and join the Lizard League. Possibly prior to this, she had a strange affiliation with the superhero, Black Samson.
Hijacking a Facility[]
Iguana hijacks a facility with other members, following the commands of her leader Queen Lizard, to search for a serum. Their hijacking would be rudely interrupted by the Guardians of the Globe. Her and her comrades would fight the heroes, mostly focusing on Black Samson, who tried to reason with her during their battle. Despite Aquarus' doubts about her, he still saved her from a collapsing ceiling. The heroes would continue to struggle until the arrival of Omni-Man, after which they were quickly defeated and their plans were thwarted.
Snake Invasion[]
At some point, Iguana would partake in an operation to turn all humans into snakes, at the behest of King Lizard. Their plans would be foiled when the new Guardians of the Globe arrive and swiftly defeated them. Despite this, they were still able to cause some civilian casualties and turn some people into snakes due to the new Guardians' lack of coordination. Possibly due to this incident, her leader would get arrested by the Global Defense Agency, leaving the league inactive for a short period of time.
Return of the Lizard King[]
Iguana would get back in action after Supreme Lizard took over as leader of the Lizard League; under his command, Iguana and the rest of the League would hit a bio research lab right before being interrupted by Shapesmith posing as the Guardians of the Globe before the actual Guardians show up. After helping up Supreme Lizard, they would go on to fight the actual Guardians. Iguana and the rest of the League would once again be defeated.
After the embarrassing loss to the Guardians, Iguana stands in front of the league along with the rest of her comrades as Supreme Lizard gives a speech for the Lizard League, trying to motivate them. Instead, Iguana is embarrassed. As they unenthusiastically chant whatever he said, Supreme Lizard gets shot in the head by none other than King Lizard himself who came back to reclaim his position.
Missile Silo[]
In Wyoming, Iguana was sent to bring forth the Lizard League and the King. She slayed two grunts before summoning the League, however one pressed the alarm with their dying breath, which was King Lizard's plan.
As they are locked within the facility, Iguana notices a door open as the Guardians (Rex Splode, Dupli-Kate and Shrinking Rae) attack. Rex and Iguana mainly fight, until the majority of the Guardians are incapacitated or dead, leaving only Rex to get walloped by the Lizard League.

Iguana's horrific end.
Desperate, Rex throws an endless barrage of explosives at Iguana, who isn't quick enough to evade one that cuts her stomach open, splitting her in two.
