Master Chief Petty Officer John-117 — the silent super-soldier face of Xbox's Halo series.
Chief is a giant — max out the height slider on your Master Chief Mii so he towers over the rest of your island residents in Tomodachi Life: Living the Dream, just like a 7-foot SPARTAN should.
Master Chief Petty Officer John-117 is the main protagonist of Microsoft's Halo franchise, introduced in Halo: Combat Evolved (2001) for the original Xbox. A SPARTAN-II super-soldier raised and conditioned from childhood, he is almost always depicted in his green MJOLNIR power armour with the visor down, partnered in the field with the AI Cortana.
Calm and quietly supportive, avoiding conflict wherever possible. Self-reliant introverts who plan carefully.In Tomodachi Life, set this Mii's sliders so Speech + Movement totals 0–3 and Thinking + Energy totals 4–7. See the full Strategist guide →
Why this fitsChief barely speaks — terse radio calls, mission-first behaviour, calm under massed enemy fire — and relies on positioning and Cortana's analysis rather than bravado. That quiet, plan-the-room profile fits Strategist (low Speech + Movement, low-to-mid Thinking + Energy).
To make a Master Chief Mii in Tomodachi Life: Living the Dream, open Mii Maker and pick an athletic adult build, a tan skin tone, a buzz-cut brown hairstyle, narrow steady eyes, and a flat set mouth, then dress him in olive-green and gold tones to evoke the MJOLNIR armour silhouette. The picker-by-picker walkthrough below works for both Nintendo Switch (LTD) and 3DS (original Tomodachi Life).
Use the system Mii Maker, then bring the Mii into Tomodachi Life: Living the Dream.
Diagrams show where the option sits in the Mii Maker picker (4 columns, scroll to reach later rows). Editor menus differ slightly between regions and console revisions — if an exact option is missing, pick the closest one.

Feature → the move to make in Mii Maker
John-117 is a towering SPARTAN-II super-soldier, so max the height slider and use a broad, heavy, athletic build.
On the rare occasions his helmet is off, he has a short brown buzz-cut and a serious, weathered face — pick a tan skin tone, buzz-cut brown hair and a flat, steady mouth.
Narrow, calm, focused eyes match his all-business soldier demeanour.
His armour is olive-green with gold visor accents, so set green as the favourite colour and dress the Mii in olive-green and gold tones.
MJOLNIR power armour & gold visor
Mii Maker has no armor or helmet part, so the iconic green MJOLNIR suit and reflective gold visor can't be built — an olive-green outfit with green as the favourite colour is the closest stand-in.
His hidden face
Chief famously almost never removes his helmet, so even the games rarely show his face; the Mii has to commit to the unmasked buzz-cut look the armour normally hides.
A Strategist-type Master Chief is the island's stoic, mission-first resident — quiet, disciplined and unshakeable, the SPARTAN who lets results do the talking. Strategists are low-drama and room best with similar personalities, exactly what LTD's roommate harmony rewards. The fun is the contrast: a 7-foot super-soldier sipping coffee in the Apartments between your most dramatic Miis. Romance isn't something he can tactically plan, though — crushes in Tomodachi Life: Living the Dream run on dating preferences, chance and birthday/zodiac compatibility — so give your Master Chief Mii a birthday and let the island decide if the soldier ever stands down.
Master Chief is SPARTAN-II John-117, introduced in Halo: Combat Evolved (2001) as the launch face of the original Xbox.
He stands about 7'2" (218 cm) in his MJOLNIR armour and 6'10" (208 cm) without it — a deliberately superhuman SPARTAN frame.
He's voiced in the games by former radio DJ Steve Downes, and is almost always partnered with the AI Cortana.
A running trait of the series is that Chief almost never removes his helmet, so his full face is rarely shown even across multiple games.
Cortana
The AI who lives in Chief's armour and acts as his constant partner, tactician and closest companion across the series.
Cortana is an AI, so there's no body to build — but you could recreate her as a stylised Mii (a blue colour theme, short hair) and house her near your Master Chief Mii as a nod to the duo. Tomodachi Life: Living the Dream won't recreate their bond automatically: friendships grow from proximity and shared time, and romance runs on dating preferences and zodiac compatibility, so you steer it.
Max the height slider for his SPARTAN frame, use a tan skin tone, a brown buzz-cut, narrow steady eyes and a flat mouth, then dress him in olive-green and gold for the MJOLNIR armour. Mii Maker can't build the actual armour, so follow the picker-by-picker steps above for Switch (LTD) or 3DS.
About 7'2" (218 cm) in his MJOLNIR armour and 6'10" (208 cm) without it. Use the height link in Quick Facts to convert that into Mii slider notches — then max the slider, since he's a giant.
No — Mii Maker has no armor or helmet part, so the green MJOLNIR suit and gold visor can't be reproduced. An olive-green outfit with green as the favourite colour, plus his rarely-seen buzz-cut face, is the closest the editor gets.
Strategist fits best — set low Speech + Movement with low-to-mid Thinking + Energy in the panel above. It matches his quiet, disciplined, mission-first profile on your island.
