Kirb

Kirb is one of the three original members of the Sacred Union, alongside Pidermin and Metal Mario. He would remain after the merge into the Brady Council until his untimely death during the events of Brady Bible 3. He is one of Luigi's fathers, and also Señor Knight's main rival.

History
Kirb was born on Popstar, a planet near the in-universe Earth. There, he served as the protector of the planet. He mainly fought off corrupt world leaders, his final battle there being his faceoff against Marx when he reached his god-like power from the Galactic Nova. After months of no threats, he took his rival's advice to follow him to Earth on the Halberd. The two landed in the Land of Pink and Grey due to lack of fuel, but since the Corruption hadn't taken form yet, they were fine. When they went to get fuel from a gas station, they met up with hitchhiker Metal Mario. He didn't have anywhere to go, so Kirb and Señor took him in for the aimless trip. Eventually, Kirb and Mario would settle down in Northern America, Señor moving to Mexico. They didn't do the gay yet but the writing was on the wall.

Two years later, they had a run-in with Guilty Conscious who attempted to murder Mario in the open, in public. They hunted him down which resulted in them meeting Pidermin and forming the Union. You know, after trying to beat the shit out of him from a misunderstanding.

He continued to serve the Union and the Council until after the defeat of Masahiro Sakurai, where he finally confessed his love to Metal Mario. They had a marriage unbeknownst to Brady, and a son afterwards. He managed to convince the part of the Council that didn't attend the wedding that Mario had his son from some random woman on a one night stand. He never had the chance to reveal the truth to the now less homophobic Council during the events of BB3, where he (you know) died.
