Study the exact outer contour used by this quiz, compare its data fingerprint with 1,024 other artwork silhouettes, then find Lucario among four choices.
- Introduced with
- Sinnoh · Generation 4
- Current type
- Fighting + Steel
One-minute visual check
Can you find Lucario without color?
Which silhouette is Lucario?
All four choices use the same black-silhouette treatment. Select one outline; names appear only after the answer is locked.
Human-reviewed clues
Trace these four parts of the outline
Follow the edge once from the topmost feature to the base. Every clue below remains visible when color and interior detail are removed.
- 01A tall upright biped stands with two long legs set well apart.
- 02Two long pointed ears rise above several rounded appendages hanging behind the head.
- 03Both arms extend sideways, and a conical spike breaks each wrist outline.
- 04A thin pointed tail curves behind one side of the narrow waist.
Decisive comparison
Lucario has a clean narrow frame and two wrist cones; Zoroark is wider above the waist because its huge jagged mane dominates the outline.

What the alpha channel measures
The figures describe this exact 475 × 475 artwork file after transparent pixels are removed. They describe the presented pose, not the Pokémon’s canonical height or body size.
- Visible width
- 59% of canvas
- Percentile 10
- Visible height
- 91% of canvas
- Percentile 77
- Filled bounding box
- 37% filled
- Percentile 12
- Left-right symmetry
- 46%
- Percentile 22
- Edge complexity
- 14.7
- Percentile 88
Percentiles rank this artwork against all 1,025 source images. Higher edge complexity means more boundary changes per unit of filled area; it does not mean the Pokémon is harder for every player.
Algorithmic comparison
Nearby shapes in the 1,025-image index
The index scales and centers each alpha silhouette, checks both left- and right-facing versions, then combines overlap with nine shape measurements.
Floragato
69.4/100 shape score
Lokix
69.1/100 shape score
Chespin
66.2/100 shape score
Mewtwo
65.7/100 shape score
These are exploratory computer matches, not a claim that players confuse the species. Pose, overlap, and thin appendages can produce surprising neighbors.
Roster context
Use current type and generation to narrow the pool
These counts come from the same 1,025-entry runtime dataset as the quiz. They are elimination clues, not features inferred from the silhouette.
