Penelope was born in Hornopolis. She used to be quickly driven in anger and killed anyone who teased her with her poisonous stinger. But with the help of a Hymenovespula therapist, she learned to control her anger, and never used her stinger since. Then when she became 16, she had to go through a rite-of-passage which stated that every Hymenovespula must learn all of the basics of therapy. She took a therapeutic class, and managed to pass by age 18.
Penelope didn't exactly want to be a therapist even though she accomplished her rite-of-passage. She instead wanted to be a famous hero so she could help the Heroes Act build up enough heroes to stop the Villains Acts growth. One day, she helped a young Serpentinoid named Serpentos (Future Serpentos III) after she got sad about losing her brother to a villain. After Penelope's help, Young Serpentos III was visited by the Spirit of the Diamond, and the spirit told Serpentos that the wasp she met was the Chosen One destined to wield it's diamond for justice. But as the years passed, Serpentos forgot about Penelope, and forgot she was the Chosen One.
Then, during the events of 'The Land Unknown', Penelope, along with her friends, redeemed a villain from evil when he attacked him until she was arrested by Xerxes XX's forces, and her friends were killed. Later on, she met Gilda, who had also been captured. They both become close friends, and they manage to escape together. They make it back to the Shell Lodge, and Penelope eventually learns she is the Chosen One of the Diamond of The Ancients. After Xerxes XX' defeat, Penelope touched the diamond, and she was given a warrior outfit, and the diamond was transformed into a scepter with the diamond engraved in it. That was when Penelope became Magnum the Great. And after the fall of the Villains Act, Magnum the Great became a protector of her UUniverses, and occasionally visits the Shell Lodge once in a while.
The Diamond of the Ancients give Magnum various god-like magical powers. She has various abilities such as telekinesis, invisibility, teleportation, telepathy, underwater breathing (Thanks to a magical bubble mask), boosted flying speed, and even the ability to manipulate elements of nature such as weather, electricity, fire, ice, plasma, and light. Non-magical abilities of Magnum include her natural 360-degree vision, her mentioned ability to fly, her experience in combat, and her poisonous stinger containing toxins that cause instant swelling and death. She never uses her stinger unless she has to. She also has empathic antennae that can detect feelings, a feature her race uses for therapeutic purposes.
As Heliope La Bizz, she is a vampiric caste of an adaptive UIS hymenopteran called a Bizzle, having the same strength and speed, but she can sense negativity. She also carries a laserum wand that fires lasers of multiple settings, and a magic wand tipped with an adamantite diamond. She had joined forces with an extremest bug-hater named Aei, who claimed that the bugs of Mactor had usurped the planet from the and are respondsable for their near-extinction, but apawn actselly meeting the Mactid sage Wistomus, the exposed leader of the "Bug Usurpers", it was reveiled that the real desicrators were the so called usurped non-bug beings themselves lead by the Anti-UIS nut Terminus, a Yateron who revived Aei as a bug Hybrid to be his perfect weapon against the Mactids and the bugs that were defending them cause they were the true inhereitors of the planet and had lied about the origins of Mactor's predicerment to try and frame the Mactid's bug deciples as violent usurpers when really it was Terminus and his followers that were the violent usurpers, of which Terminus mind-controled Aei and forced her to try and kill La Bizz, but the mere act of La Bizz refusing to fight even on the path of dying drove every single follower of Terminus to lose their nerve and stopped supporting him, of which just as Terminus activated the kill switch on Aei for disobeying him, La Bizz was triggered angerly as instinct took over even a dying body and made her suck Terminus dry of his blood. La Bizz became a hero to both insects and beings as Wistomus and his reminant people, while still insistent that bugs inhered the planet, desided that non-bugs should not be left out of it as well, putting the planet on the path of peace and the Matids a chance to recover.
