Become Rivals' Iron Fist in your Minecraft world, then switch back to your character with a single key.

Bring Iron Fist, Lin Lie from Marvel Rivals, into your regular Minecraft: Java Edition world. Press H to switch between your character and Iron Fist; K opens the profile and commands. Single-player only, with no arenas or additional modes.
Fight with a five-punch combo, defense and counterattack, dash kick, Iron and Stone uppercut, meditation, three midair jumps, wall-running, Chi absorption, and the Living Chi ultimate. Abilities affect enemies and health in the Minecraft world; damage and health values are scaled to fit. Kumiho's ally healing helps your tamed wolf.
The model, textures, body and aiming animations, voice lines and sound effects, portraits, icons, fonts, and health bar materials are the original ones from Rivals, read from the player's installed copy during gameplay. The profile also lets you preview the original body gestures; separate items and lobby/MVP sequence set pieces aren't added. Marvel Rivals isn't launched or modified, and no content from either game is included in the download.
Requires 64-bit Windows, an account that owns Minecraft: Java Edition, and your own Marvel Rivals installation. Melty sets up Minecraft 1.21.1 and everything needed to launch the mashup with one click.
Version 0.1.2 passed two real-world five-minute tests covering installation, character switching, combat, abilities, original assets, and interface, with a full review of the recordings. This version is for the single-player world owner.
