Onimusha Bestiary: All Enemy Types, Weaknesses, and Strategies

Updated: 2026-08-064 sections

This bestiary catalogs the enemy types you encounter in Onimusha: Warlords and the best way to handle each. The game's Genma come in a handful of archetypes, and once you recognize an archetype, the correct response is usually obvious. Use this guide as a reference when a new enemy appears: identify its type, check its weakness, and apply the matching tactic.

Two principles apply across the entire bestiary. First, the Oni Gauntlet means every kill feeds your upgrades and healing, so engaging enemies is usually better than avoiding them -- especially early, when souls matter most. Second, the Issen counter and charged attacks work on nearly every non-boss enemy, so mastering those two techniques handles most of the bestiary without needing specific counters.

Elemental matchups add a second layer: Raizan stuns, Enryuu burns area damage, and Shippuu clears crowds. Matching the right element to the enemy formation multiplies your effectiveness and conserves resources.

Basic Genma and Soldiers

Basic Genma soldiers are the most common enemy and the backbone of the bestiary. They are slow, telegraphed melee fighters that appear in nearly every area. Individually they are fodder -- easy to stagger with any weapon and simple to Issen-counter once you learn the timing. They exist primarily to feed you souls, so treat groups of them as upgrade fuel.

Their danger comes only from numbers. A single soldier is trivial, but three or four surrounding you can chip you down if you stand still. Keep moving, pick them off one at a time, and use charged attacks to stagger the front of a group so the rest file in manageable. Yellow souls from kills keep you healed through their chip damage.

Because they are weak to everything, basic soldiers are the best practice targets for learning Issen counters and charged-attack timing. Drill these techniques against them early, and the skills will carry you through the entire bestiary and into the boss fights.

Specialized Genma

Three-eyed demons are the step up from basic soldiers: more aggressive, faster swings, and less forgiving of greedy combos. Respect their wind-ups and punish only after they commit. A Raizan stun is a safe way to interrupt them before they start their string, and a charged attack during their recovery stagger-locks them for follow-up.

Armored or shielded Genma shrug off frontal hits, so mash combos bounce off their guard. Flank them, break their guard with a charged attack, or stagger them with Raizan's thunder magic to open them up. Never stand in front of one trading blows -- circle and punish from the side or back.

Ranged Genma (archers and similar) are low on health but dangerous in groups, because they chip you while you fight melee enemies. Always close the distance and kill them first, or break line of sight behind corners. Fast, darting enemies close gaps quickly and can stunlock you if surrounded; use Raizan to lock them down, then clean up one at a time. The Genma that impersonates Samanosuke is a mini-boss-grade fast enemy -- treat it with caution and bait its attacks.

Boss-Tier Genma

The boss-tier Genma follow their own patterns and are covered in depth in the boss rush guide, but the bestiary context helps. Osric is a slow, telegraphed giant that teaches the bait-and-punish rhythm. Reynaldo is faster and more aggressive, demanding tighter dodges. Marcellus is the first real difficulty spike, punishing reckless aggression and rewarding patience.

Hecuba is an insect-like Genma whose fight rewards ranged pressure and magic when she exposes her weak point. The enhanced Marcellus near the end is a tougher version of the roof fight -- faster, more aggressive, and more damaging. Fortinbras, the king of demons and final boss, is a multi-phase endurance test capped by the scripted Onimusha transformation.

For all boss-tier Genma, the same rules apply: arrive with a maxed or near-maxed weapon, a full magic meter, and healing items; bait attacks and punish the recovery; and lead with your strongest elemental magic -- Enryuu for damage, Raizan to stun aggressive bosses. Patience and resource management beat aggression against every boss in the bestiary.

Frequently Asked Questions

Basic Genma soldiers are the most common enemy. They are slow, telegraphed melee fighters that appear in nearly every area and serve mainly as fodder for souls and as practice targets for Issen counters.

Raizan's thunder magic stuns enemies and interrupts their attacks. It is the best element for controlling fast, aggressive foes and for breaking up crowds before they surround you.

Flank them, break their guard with a charged attack, or stagger them with Raizan's thunder magic. Frontal mash combos bounce off their guard, so never stand in front of one trading blows.
