Since the game’s "Hero Mode" (create-a-character) is notorious for having locked hair styles, movesets, and limited aura options based on your "style," a modded menu could bypass these restrictions:
Jtag/RGH scripts could allow you to scale your character's height and muscle mass beyond the standard presets, letting you create a "giant" or "micro" fighter for local versus play. Dragon Ball Z Ultimate Tenkaichi [Jtag/RGH]
Force-assign any Super or Ultimate Attack (like Omega Shenron’s Minus Energy Ball) to your custom hero, regardless of their chosen fighting style or progression. Dragon Ball Z Ultimate Tenkaichi [Jtag/RGH]
