The boys mod

Compound V is the core item: it grants a random permanent superpower, while Temporary V gives a random power with a real timed effect. Supe Virus removes a player's superpower again. Syringe items with custom animations share one injection-style animation system, and the hero HUD displays the active power, its state, ability lock timers and charge progress. The HUD can slide off-screen and be hidden.

Abilities cover lasers from the eyes drawn as real 3D beams, flight with hover mode and vertical movement, super speed, impact dash, impulse shockwaves, immortality with fire immunity and regeneration, and a morph ability that changes a player's visible name and skin head for other clients. Laser damage causes burning and suppresses regeneration, and a laser eye-position editor matches beam origins to the player's skin. Admins open a hero menu to assign powers and build combo abilities, and the interface uses Russian power names.

The mod is unofficial and affiliated with none of the rights holders. It requires Geckolib, and it runs on client and server, so the server and every player need it. Files exist for Forge only, for 1.20.1, with 1.0.0 as the latest file. The license is All rights reserved, so the code is not open source.
