Galatea

Galatea (or "Tea" as she prefers to be called) was a clone created by Professor Hamilton from a DNA sample extracted from Supergirl. She was created for the purpose of protecting humans from the likes of Superman and other Justice League Members. She shares identical powers and looks to Supergirl, her only difference being age, which is accelerated to her prime. She is extremely arrogant and prideful, but does believe what she is doing is for the good of humanity. She can be made dangerously angry if she is compared to her non-clone counterpart, who she is determined to outperform. She is also shown to have feelings like compassion, as she has a special connection with her creator, Professor Hamilton, who she views as her "father".
