Angelecticea (AKA Justice) is Mike's ex girlfriend.
She was a major plot device in the Aquablade Chronicles in season 2, only to have that changed when she tore out his heart and pissed on it, just like he wanted her to. Because Aquablade11 has a watersports fetish (for reference, google "furry watersports" on Google Images). Hell, he sent 14-year-old Angelecticea a video of him peeing on himself when he was 19.
She then left him for another man, he married a girl he knew for 3 months, and everybody lived happily ever after.
