Full Metal Kaiju Hunters Knifehead and Onibaba Prep Guide
Pattern homework bosses that teach telegraph discipline before Otachi and Slattern badges.
Knifehead and Onibaba are the pattern homework bosses of Full Metal Kaiju Hunters. They may not always sit on a flashy public badge percentage row the way Otachi, Leatherback, Mega Kaiju, or Slattern do, but they teach the habits those badge clears assume you already own: lateral movement, named telegraphs, and equipment that belongs to a plan instead of a panic. This guide turns both fights into drills you can finish in a focused session during early alpha (~v1.0b).
Read the parent overview on How to Beat Bosses first if you still mash city muscle memory into every named fight. For the full monster card list, open Kaiju Roster. For tracker badges that do have public rows, use Badges and Milestones.
Why these two matter before badge walls
Otachi filters grab literacy. Leatherback filters body-check discipline. Mega Kaiju filters phase planning. Slattern filters endurance. Knifehead and Onibaba filter whether you can watch the wind-up without freezing your feet. Skipping them feels fast until the same charge-path wipe appears three times on a harder badge.
There are still no promo codes that skip homework — see Codes. Farm DNA with How to Farm DNA if chip damage is the real wall, not the telegraph.
Shared prep checklist
- Finish Getting Started and fix dodge habits in Combat Controls.
- Bind a kit in the Loadout Planner — one weapon identity, named equipment windows.
- Warm up on Hong Kong or Neo Tokyo from Maps and Missions.
- Enter with one job written down (“learn charge exit” or “name the wipe telegraph”).
- Leave after two focused wipes; tilt attempts teach nothing.
Knifehead — stop staring, start stepping
Exam: Tunnel vision. Knifehead wants you locked on the head hitbox while your positioning collapses.
What to practice
- Lateral exits after every short burst — not backpedaling into clutter.
- Charge-path prediction — Strafing Runs belong on a lane you already called, not a panicked reaction.
- Short weapon strings — Tesla Fist or Enforcer bursts, then step out. Flame Turbine helps when the path is readable and you pre-drop a zone.
Recommended kit sketch
| Slot | Suggestion |
|---|---|
| Weapon | Enforcer for readable mid-range, or Tesla Fist if your bursts are clean |
| Burst | Nuclear Air Strike reserved for a true plant — not the opening roar |
| Control | Strafing Runs on predicted lanes; Attack Helicopter while rebuilding space |
| Perks | Enhanced Stabilizers; Mag Lock Anchors if displacement shows up |
Common Knifehead fails
- Standing still to “aim better” during an obvious charge.
- Spending every bomber in the first twenty seconds.
- Swapping Jaegers every wipe instead of fixing the exit step.
Attempt loop
Warm up → one Knifehead attempt → one-sentence note (“charged while I was still M1ing”) → change only the exit habit → second attempt → stop or farm DNA.
Onibaba — write the telegraph or repeat the wipe
Exam: Pattern literacy. Onibaba rewards hunters who take notes and punishes vibe-only melee.
What to practice
- Named tells — after each wipe, write the attack that killed you in plain language.
- Strike timing — Bunker Buster and Nuclear Air Strike belong to those named tells.
- Clean M1 discipline — pack-style pressure rewards strings you can interrupt; greed strings you cannot.
Recommended kit sketch
| Slot | Suggestion |
|---|---|
| Weapon | Flame Turbine for zone control, or Enforcer for readable trades |
| Armor answer | Bunker Buster on the stubborn grounded window you already named |
| Panic control | Keep one tool unspent for the third-minute mistake |
| Perks | Titanium Ribbing if limb chip ends runs; Stabilizers for recovery |
Common Onibaba fails
- Repeating the same greedy melee string after two identical deaths.
- Changing five loadout slots between attempts.
- Treating the fight as a damage race instead of a note session.
Attempt loop
City warm-up → Onibaba with full focus → note the kill telegraph → adjust one assignment → second attempt → if notes stop improving, end the session.

Do not invent Knifehead or Onibaba win rates if public trackers have not listed them. When rows appear, update your personal notes and re-check Version History.
Jaeger notes for homework fights
- November Ajax — Best practice frame when consistency matters more than prestige flexing.
- Cherno Alpha — Stable if you accept slower repositioning and want trade resistance.
- Obsidian Fury — Fine when you can re-enter after dodges without panic.
- Midnight Winter / Saber Athena / Apex — Only if your hands already own equipment sequencing; homework bosses are not the place to learn a new frame and a new telegraph at once.

Team option
Duo homework works when one pilot calls the charge path and the other holds burst. Overlapping Air Strikes on Knifehead teach nothing. For call language and Discord grouping, use Co-op Team Hunts and Discord Community.
Micro drills between attempts
- Five minutes of lateral dodge-only reps from Combat Controls.
- Ten minutes of DNA top-up if upgrades are the blocker — How to Farm DNA.
- Prestige evaluation only if you are coin-capped and mechanically ready — How to Prestige.
Patch-day warning
Weapon and VFX passes can change telegraph readability overnight. After any Tragic Works Discord weapon note — including “all Jaegers will be getting more weapons” direction — re-test buttons in Workshop before another Knifehead or Onibaba exam. Confirm build era on Version 1.0b.

Finish Knifehead and Onibaba as homework, not as afterthoughts. The badge ladder gets quieter when your notes already name the telegraphs.

Quick answers to the most common questions.
Should I fight Knifehead before Otachi?
Yes. Knifehead and Onibaba teach telegraph and movement habits that Otachi and later badge bosses assume you already have.
Do Knifehead and Onibaba have badge win rates on this wiki?
Not cited as public tracker rows here. Treat them as prep bosses and avoid invented percentages.
What equipment helps on Knifehead?
Strafing Runs on predicted charge lanes, Attack Helicopter while rebuilding space, and Nuclear Air Strike only on a true plant window.
What is the best Onibaba habit?
Write the wipe telegraph in one sentence after every attempt and change only one loadout or movement variable next time.
Which Jaeger is best for these homework fights?
November Ajax or a Prestige-ready Cherno Alpha for consistency. Learn the telegraph before experimenting with Apex or Midnight Winter.
Where do I go after clearing both?
Move to Defeat Otachi Badge, then Leatherback, Mega Kaiju, and Slattern guides on the badge ladder.
