Coincidental Character Creation

Coincidental Character Creation is an anomaly where the Personalization A.I. creates characters similar to those seen in later installments of the Super Mario Bros. series, despite not knowing about said characters. These characters often have some differences, likely due to the unaware nature of the Personalization A.I. regarding the characters it creates. It most commonly appears with less major characters, or variants of characters that only appeared in later games. It is possible that this anomaly has inspired some characters created later in the Super Mario Bros. series.

Examples
There have been several documented examples of Coincidental Character Creation. Below is a list of examples of the anomaly.

Theorizing
Coincidental Character Creation appears to have inspired some characters created by Nintendo after Super Mario 64, the most notable example being Waluigi, though the exact number of characters inspired by Coincidental Character Creation is unknown.
