Echoes

Echoes (エコーズ) is the Stand of Koichi Hirose, featured primarily in Diamond Is Unbreakable.

Rare among Stands, Echoes takes three distinct forms called "ACT"s, which Koichi may call upon alternately.

Egg
Manga Debut: Chapter 279, The Nijimura Brothers (6) Anime Debut: Episode 78, The Nijimura Brothers (2)

Echoes' Egg form is not named, but it could be considered ACT0.

Abilities
Egg Throw: Koichi cannot move his Stand in this form. However, during his battle against Keicho, he simply throws it at him while he is distracted. Nothing results, however, when Keicho intercepts this attack.

Development
It makes an appearance during the battle against Keicho, though immobile and unresponsive to Koichi's command. Keicho becomes defensive, believing that it poses a threat to his father.

Koichi calls on it in his battle against Tamami, during which it develops into ACT1.

Appearance
Echoes first appears as a large, cracked egg.

Echoes ACT1
Manga Debut: Chapter 287, Koichi Hirose (Echoes) (4) Anime Debut: Episode 80, Koichi Hirose (Echoes)

Abilities
Sound Maker: Echoes ACT1 can write a sound effect in Katakana on anything, from human flesh to the ground, and have that sound repeat itself over and over with increasing volume. Echoes can shoot sound effects from both its tail and hands.

This ability seems to allow it to also transfer words, as Koichi uses it to show his mother he is telling the truth.

The effect can be broken with enough willpower, as Yukako dispels the writing that Koichi puts on her.

It has the longest range of all Acts, and can go up to 50 meters from its user.

Development
ACT1 hatched from its egg during Koichi's fight with Tamami, becoming the only version he can access until his confrontation with Yukako.

Appearance
ACT1 generally resembles a turtle with a beak and a long, patterned tail. It has two wheels and two small arms.

Personality
It speaks like a child, using nonsensical words and growls. It faithfully meets Koichi's command.

Echoes ACT2
Manga Debut: Chapter 300, Yukako Yamagishi Is in Love (7) Anime Debut: Episode 83, Yukako Yamagishi Falls in Love (2)

Abilities
Sound Maker, ACT2: Echoes' second form increases its sound abilities beyond its first form's capabilities. Echoes can write a sound effect on any surface. However, unlike ACT1, it is only able to shoot sound effects from its tail, limiting it to only one sound effect at a time. When the sound effect is touched, an effect related to the sound is produced.

Enhanced Speed: Foreshadowing the speed of ACT3, ACT2 gains a massive increase in speed - fast enough to give the impression of disappearing into air.
 * Hyooo (ヒョオオ) - A strong wind is produced.
 * Dougon (ドグオン) - The toucher is knocked back a great distance.
 * Byoyon (ボョヨオン) - The object becomes elastic and bouncy.
 * Jyuu (ジュー) - The object radiates low heat.
 * Dorarara (ドラララ) - An attack rush of Crazy Diamond shaped fists attack the enemy''' (Eyes of Heaven only)

Development
During the battle with Yukako, Koichi gains access to Echoes ACT2.

Appearance
ACT2 takes a more humanoid - though smaller - form. It still has a long tail with a pyramidal tip and shell-like outer areas. It has boots and heart-shaped kneepads. It has a large highcollar fused with shoulder weights with "S2" written on the back.

Personality
Unlike ACT1, ACT2 is completely mute.

Echoes ACT3
Manga Debut: Chapter 358, Sheer Heart Attack (5) Anime Debut: Episode 97, Sheer Heart Attack, Part 1

Abilities
Unlike Echoes' first two forms, ACT3 does not fly and has a much shorter effective range. However, it is extremely fast.

Sound Maker, ACT3: Same as ACT2's Sound Maker.

3 Freeze: ACT3 rapidly punches its target before attributing a "freezing" or stopping effect by greatly increasing its effective weight. It can only affect one target at a time. For example, Killer Queen's Sheer Heart Attack is forcibly sunk into the pavement by this ability, and, according to its user, the effects were as if there were 40-50 kilograms of weight on his left hand.

This effect lasts only if the target remains within 5 meters of ACT3. The closer the target gets, the more weight is added.

Development
Koichi discovers Echoes ACT3 during his first confrontation with Kira.

Appearance
ACT3 is a completely humanoid Stand with turtle shell-like pieces on its body. It's tail is now more or less a spike protruding from a cloth wrapped around its waist with the number 3 printed on the front.

Personality
ACT3 has a somewhat independent, bratty, and foul-mouthed personality, tending to quote, Bruce Willis' character from the Die Hard film series. Despite this, it remains loyal to Koichi, following his orders and referring to him as Master.

Cult Jump (GB)
Echoes ACT1 appears without his Stand user, Koichi, as one of the ten characters from the JoJo's Bizarre Adventure franchise on the game.

All-Star Battle (PS3)
All versions of Echoes appear as Koichi's Stand during gameplay. Different moves correspond to different Stands. A full list can be found here.
 * His GHA has ACT1 pelting the victim with a barrage of deafening sounds, ACT2 knocking them high into the air, and ACT3 beating them up with 3 Freeze and inflicting his increased gravity on them, causing them to fall down hard.


 * Koichi's HHA is Echoes 3 Freeze, which will make the opponent heavier, temporarily slowing their movement and removing their ability to jump.

Trivia

 * According to JOJOVELLER, ACT1 is based on an alien larva but finally looked like an insect. ACT2 looks like a standing Coypu.
