Tobirama Senju — Second Hokage

Bring the Second Hokage to Risk of Rain 2 with a connected three-hit taijutsu combo, a surging Water Dragon, two-charge Flying Raijin, and a sustained Tandem Paper Bomb barrage. Includes a custom animated survivor and English/Japanese voice options.

AI was used extensively throughout this mod's development, including programming, animation and rigging workflows, effects integration, debugging, test tooling, and documentation. Human direction, asset selection, playtesting, and iteration shaped the final result. The purchased character model is credited separately below; this disclosure does not describe it as AI-generated.

Abilities

Damage percentages scale from character damage before enemy defenses. Tandem's total requires a target to remain inside the barrage for every pulse; its decorative finale adds no separate damage. Defaults can be changed through configuration. Cooldown recharge begins when the skill state ends.

Flying Raijin controls

• Press Utility to throw the burst. The anchor automatically teleports you when it hits an enemy or terrain, if a safe arrival position is available.
• Release Utility, then press it again while the anchor is airborne to teleport early. This recast costs no additional charge.
• After the teleport resolves, another fresh press can spend the second charge. Holding the button does not spend both charges automatically.
• An anchor is consumed after one teleport. Invalid destinations fail safely; an expired anchor does not teleport you to an arbitrary point.

Charges replenish one at a time. The voice declaration plays on a successful teleport, while the throw uses a short whoosh. Rapid consecutive teleports can share a voice line to avoid overlapping speech; both gameplay actions still occur.

Movement and voice options

Ordinary movement uses the calmer walking gait; the game's rebindable Sprint input activates ninja sprint. Additional-jump flips respect the jumps available from the game and items. Tobirama takes 50% less fall damage, without changing gravity or ordinary incoming damage.

Choose either outfit in the loadout:

• 2nd Hokage - English Voice
• 2nd Hokage - Japanese Voice

Both use the same model, appearance, and ability icons. They select different voice sets; shared nonverbal effects remain the same. Character selection has no Tobirama selection voice cue.

Installation

Install TobiramaSenju with r2modman or Thunderstore Mod Manager and allow its listed dependencies to install. Start the game modded and select Tobirama Senju. Young Sasuke is not required; Tobirama uses its own plugin, assets, and configuration.

For manual installation, install the dependencies from manifest.json, then copy plugins/TobiramaSenju into the chosen profile's BepInEx/plugins folder. Keep TobiramaSenju.dll and its entire Assets folder together.

Upgrading from a private candidate: close the game and move the previous Tobirama plugin folder outside BepInEx/plugins before installing. Keep only one enabled copy of TobiramaSenju.dll. Back up BepInEx/config/henry.TobiramaSenju.cfg. Existing saved values are preserved, so an older test configuration can override the new defaults. See CONFIGURATION.md for the exact current damage entries; no automatic configuration migration or settings overwrite is performed.

The configuration file is created after the first launch. Restart after changing it. Voice, preparation, and shared sound-effect levels have separate controls in its Audio section. In-game skill descriptions use the loaded damage settings.

Tested build and current limitations

• Based on the accepted RC02 playable build, version 0.12.0. This packaging pass changes documentation only; the tested runtime files are unchanged.
• Tested in solo-host play on Risk of Rain 2 1.5.0. Independent host/client multiplayer has not been verified. The plugin requires matching mod versions for multiplayer; that requirement is not a claim of multiplayer certification.
• Character-mounted item display models are disabled for Tobirama. Inventory, item stats, effects, equipment, and HUD feedback remain functional.
• Melee is directional and range-limited. A moving enemy—or the gap between a large enemy's separate hurtboxes—can fall outside the final kick's short forward contact volume.
• In-place locomotion can still show foot sliding on slopes or abrupt turns. Compatibility with every mod combination and extended item-heavy performance have not been established.
• Formal passive design remains deferred. The underlying fall-damage reduction is retained without a named passive entry in character selection.

For useful bug reports, include the mod/game versions, difficulty, character level, items, whether you were hosting or joining, and a short reproduction or clip. For missed attacks, note attack speed and movement speed separately.

Credits and asset provenance

• SummerForce — Blender character model, purchased/sourced on 3DExport. The model was adapted and optimized for this survivor while preserving its likeness and proportions.
• Project direction and playtesting: the mod's creator, through repeated art direction, asset selection, and in-game feedback.
• AI-assisted development: OpenAI Codex was used extensively for implementation, animation tooling and iteration, integration, debugging, testing support, and documentation.
• Modding tools and infrastructure: BepInEx, R2API, the Risk of Rain 2 modding community, and lessons carried forward from the Young Sasuke project and ArcPh1r3's Henry Tutorial framework.
• Water Dragon prototype geometry: supplied extracted Naruto Shippuden: Ultimate Ninja Storm 4 material, adapted for this mod. Its water materials, motion, splash effects, and gameplay integration were adapted for this survivor.
• Voice recordings, preparation/kunai sounds, ability artwork, and portrait: supplied Naruto material, edited or cropped for integration; rights remain with their respective owners. No replacement speech was synthesized.
