The proud guardian of the Master Emerald and Sonic's eternal rival from Sega's Sonic the Hedgehog series.
Knuckles is gruff, blunt and rarely jokes — after importing him into Tomodachi Life: Living the Dream, drop the pitch and keep the tone serious on LTD's voice sliders to match his no-nonsense delivery; those sliders are an LTD-exclusive Mii Maker option the Switch system Mii Maker doesn't have.
Knuckles the Echidna is a character from Sega's Sonic the Hedgehog franchise, created by Takashi Yuda and introduced in Sonic the Hedgehog 3 (1994). The last surviving member of the echidna clan, he is the guardian of the Master Emerald — a relic with the power to control the Chaos Emeralds — and his fierce duty to it shapes nearly every storyline he appears in.
Diligent and productive, turning every plan into action. Results-focused and efficient in everything they do.In Tomodachi Life, set this Mii's sliders so Speech + Movement totals 8–11 and Thinking + Energy totals 4–7. See the full Achiever guide →
Why this fitsKnuckles is portrayed as serious, dedicated, and short-tempered when his duty is challenged — he doesn't joke like Sonic, he checks the box and moves on. That status-and-duty profile fits Achiever (high Speech + Movement, low Thinking + Energy).
To make a Knuckles the Echidna Mii in Tomodachi Life: Living the Dream, open Mii Maker and pick a stocky muscular frame, a bright red skin tone, serious eyes, and a stern frown — Mii Maker can't draw his dreadlock-style head spines, so colour and frame do the heavy lifting. 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.

On a Nintendo 3DS, open Mii Maker → QR Code / Image Options → Scan QR Code and point the camera at it, then bring the Mii into the original Tomodachi Life. The Switch / Switch 2 has no camera, so it can't scan Mii QR codes — for Tomodachi Life: Living the Dream use the step-by-step instructions above (or the online Mii creator).

A rival-turned-ally — Knuckles first fought Sonic after Eggman deceived him, then became one of his steadiest allies.
Shadow the Hedgehog
A fellow member of Sonic's wider cast and an occasional rival — the two have clashed before fighting on the same side.
Recreate Sonic and Shadow to gather the cast on one island — but Tomodachi Life: Living the Dream decides relationships its own way. Friendships grow from proximity and shared time, and romance runs on dating preferences, random crushes and zodiac/birthday compatibility, so the game won't recreate the rivalries for you; house them close and steer their conversations.
Build cheat-sheet
Feature → the move to make in Mii Maker
Bright red head to toe — pick the warmest red skin tone the editor offers (or rely on a red colour scheme).
Stocky and muscular — push the body slider toward broad and heavy; he's the powerhouse of the cast.
Serious eyes over a stern frown — choose hard, focused eyes and a downturned mouth.
His white crescent-moon chest marking can be hinted at with in-game clothing after import.
His dreadlock-style head spines
Mii Maker has no spined or dreadlocked hairstyle that matches, so the head spines can't be reproduced — the red colour and stocky frame carry the likeness instead.
The two knuckle spikes on each fist
Miis have no fist or glove parts, so his namesake spikes can't be shown. This is an inspired-by, human-form Knuckles built on colour and build.
Knuckles is the last surviving member of his echidna tribe and the lone guardian of the Master Emerald.
He can glide long distances and climb sheer walls using the spikes on his gloves.
Unlike Sonic, Knuckles can swim.
He debuted as an antagonist — Robotnik tricked him into fighting Sonic and Tails before he realised the deception and switched sides.
No — Mii Maker can't build an anthropomorphic echidna with dreadlock spines and knuckle spikes. This is an inspired-by, human-form Knuckles where the bright red colour and stocky muscular build carry the likeness.
Pick the warmest red skin tone (or lean on a red colour scheme) and push the body slider toward broad and muscular. A stern frown and hard eyes finish the duty-bound guardian look; hint at his white chest crescent with in-game clothing.
Achiever fits him best — set high Speech + Movement with low Thinking + Energy in the panel above. It matches his serious, dedicated, duty-first character that doesn't joke around like Sonic.
Yes — build Sonic and house him near Knuckles to rebuild their rival-turned-ally dynamic. LTD bonds form from time spent together rather than canon, so keep them close and see whether they clash or click on your island.
