If you are running the REX build and you want matches to feel more explosive, faster, and less “tournament balanced,” the easiest route is adding high-impact custom character movesets and moveset packs. “Overpowered” is subjective, but in practice people usually mean kits that have one or more of these: very strong confirms, high damage output, extreme mobility, oppressive specials, or unusually safe pressure.
Below is a curated list of popular, high-impact additions, each with a direct GameBanana link.

Quick REX tip so you do not brick your build
Add mods a few at a time, and keep backups of your REX install. Some entries are built around certain bases or assumptions (addon vs full slot, specific file layouts, etc.), so testing incrementally saves you from mystery crashes.
If you tell me how you are installing into REX (manual drop, BrawlInstaller, another method) and whether you are adding to existing slots or new slots, I can sort this list into a safest install order.
