"But... King Crimson has already... seen through it."
It has a sub-Stand ability, Epitaph (エピタフ (墓碑銘) Epitafu), which was primarily introduced by Vinegar Doppio, Diavolo's split personality.
King Crimson is a humanoid Stand of a height and build similar to Diavolo's, but tends to look much bigger. Its body is covered by a raised diagonal grid; save for its face, neck, shoulder guards, elbows, hands, abdomen, crotch, knees and feet/footwear.
[Click] Basic Attack
Above average punching speed with above average damage.
[Q] King Punch (Level 1, 8 second recharge, Cost 15 Stamina)

[E] Barrage (Level 30, 9 second recharge, Cost 15 Stamina)
King Crimson does a high damage barrage that stuns enemies hit by it, and can do King Punch while the barrage is happening as well.
[R] Epitaph [Level 50, 18.5 second recharge, Cost 30 Stamina]
Makes you invulnerable for 5 seconds, and if used before a time stop, allows you to move in the time stop. If someone attacks you while this is active you will dodge the attack, though this is only for looks as you are already invincible.
[F] Time Erase [Level 70, 42.5 second recharge, Cost 0 Stamina]
Same effect as Epitaph, but invulnerable for 8 seconds, it gives Time Stop movement if the attack is used before or after Time Stop was activated. Attacks can be used during Time Erase.
