The generator produces names that look like real player names rather than * artificial "Bot1234" patterns. It supports several name styles:

* *

Syllable-based names (e.g., Glarion, Vexon)
Prefix + base (e.g., ProGamer, TheViper)
Base + suffix number (e.g., Notch_2011)
Gaming tags (e.g., xXShadowXx)
Compound words (e.g., DarkKnight)
