Anime Debut

Gatchaman Versus Turtle King

Ken Washio (鷲尾 健, Washio Ken), also known as Ken the Eagle and Gatchaman, is the team leader & tactician whose bird style is based off from the eagle. When not in costume, Ken works as an aircraft test pilot and delivers parcels by air mail.

Ken's father disappeared when Ken was 4 years old. Ken grew up believing that his father had died in a plane crash, while his mother eventually died of illness when he was 11 years old. He then spent most of his life under the wing of Dr. Nambu, undergoing the training to become Gatchaman.

To keep his cover, Ken got a job as a test pilot and delivery boy while living in his father's old office on a small airfield.


Ken the Eagle

Ken is a young man with shoulder-length, somewhat messy brown hair, as well as blue eyes. His civilian clothing consists of a red-and-teal T-shirt with the number "1" on it, white bellbottom pants, and occasionally a pair of blue flight gloves. In the two sequel series, Ken's civilian clothing changes so that he wears a blue and soy Blue "1" shirt and has straight-legged pants.

His eagle-like Bird Style is colored white, with blue gloves and boots.. He wears a long white feathered cape with a red interior, as well as a white helmet with red and black accents. The visor on his helmet is colored blue and patterned after an eagle's beak. As with the other Bird Styles, it bears a red "Gatchaman" emblem and has a "G"-themed belt.


Ken was redesigned to have short hair in the OVA remake, and his usual civilian outfit is a blue hoodie and jeans. Rather than having a "1" on his clothing, it is relegated to being a symbol on a necklace that he wears.

His Bird Style was also redesigned to be primarily blue in the bodysuit, although bearing white accents to it and keeping the white cape and helmet. His "G" belt was taken away, with only the symbol existing as a built-in part to his suit.

Cancelled Imagi Film Project

Ken's out-of-costume appearance shifted between his OVA look and his original look in drafts, while his Bird Style was to initially take more inspiration from the 2000 NTT Gatchaman project (in having a more armored appearance).

Other concept designs and trailers took inspiration from the OVA with the uniform, although the suit was primarily white (as with the original series) but with blue trim and accents.

Ken the Eagle

Infini-T force

Unlike the previous redesign, this Bird suit version was much inspired to the original with armored bird suit and some more stylished accesories such as his classic helmet, chest, gloves and boots. He has now more sophisticated support tools.

While as for the civillian appearance, he has been redesigned with taller body, grey short hair, and stubble. The outfit is a black short-sleve sweater with red tie, blue formal jacket, white pants with balck belt, and big black boots.


Ken is usually a calm and collected person, but when faced with a crisis he can get swept up in emotion and requires the help of his team to pull himself through. He is an avid reader, reading books in his spare time. When out in the field, he tends not to use his real name and does not appear to be good with money either, often having Jinpei pay his bills at Jun's snack stand.


Kentaro Washio/Red Impulse

Ken was close with his father and aspired to become a good man like him. Unbeknownst to Ken, Kentaro had to undergo a secret mission and had faked his death in order to investigate Galactor further.

When meeting Red Impulse, Ken felt a familiar presence but could not find out why until episode 53, where this mysterious man revealed that he was indeed Ken's father. Unfortunately, this revelation came immediately before Red Impulse sacrificed himself to destroy Galactor's V2 missile.

Ken was upset that he lost his father again, but after coming out of his depression, he was only more determined to finish off Galactor. A ruse of Gel Sadora by pretending to have Red Impulse alive caught-off guard Ken, but the lieutenant revealed this conspiracy against him. So again, Ken had to remember his father's way of life and continue to use the Gatchaman mantle and protect Earth. It was not until Infini-T Force that Ken really stood up as a true leader and was not affected by his father's loss anymore.

Joe Asakura

As second-in-command of the team, Joe is usually the one Ken communicates with the most next to Jun. They tend to butt heads with each other due to their differing personalities and way of handling situations. But Ken sees Joe as one of his closest friends and allies, and knows when to count on him in missions, even if both of them disagree.


Ken sees Jun as a respectable and trustworthy teammate, but is usually ignorant of Jun's feelings for him due to his intense focus on missions, neither does he have any interest in starting a romantic relationship with her or anyone else. In spite of this, Ken appreciates what Jun does to help him in situations.

Emi Kaido

In the Infini-T Force series, ken was taken to the other dimension, but that dimension is the modern day of Japan. Ken and the other heroes meet Emi Kaido (Or Kyoko in the manga) The Young Girl Who's doesn't care about anything. Ken, as the oldest guy between his Infini-T Force allies, is really care about her and decide to protect her from villains who's looking for the case that possess inside her.

Ken later appears as part of a crowd lured in by the Doronbo gang's latest scam in episode 24, although his shirt is depicted with a "G" on it (as opposed to a "1") for the specific shot. All of his out-of-costume appearances use his streetwear from the original series, as opposed to the Gatchaman II/Fighter design.

Alterations in English Adaptations

The first English adaptation, "Battle of the Planets", he is renamed as Mark and significantly altered his personality as well. Mark is depicted as more of an ideal leader and role model for the younger viewers, and is continuously praised by 7-Zark-7. He seems to be calmer and more restrained than Ken, and also seems to reciprocate Princess' feelings for him (while Ken brushed off Jun's flirting or remained oblivious).

Due to the anachronical way of adapting episodes, Mark's father's fate is confusing whether watched in the original Gatchaman order or Sandy Frank's suggested order. It is known that Mark's father was believed to have been murdered on Riga, causing Mark to want to avenge him. Red Impulse was renamed "Colonel Cronus" and depicted as a mentor and old friend of Mark, but was supposedly killed and impersonated by Zoltar, although he later turned out to be alive. Finally, Colonel Cronus later revealed to Mark that he was his father, and went to sacrifice himself. However, some dialogue by Zark that claimed that Colonel Cronus ejected from his ship and survived the explosion. Another episode had a scene of Ken at Red Impulse's grave altered in dialogue to imply that Mark had an older brother that had died at some point, though this brother is never mentioned again.

In "G-Force: Guardians of Space", he is renamed Ace Goodheart, and his backstory is much closer to the original, as well as the Red Impulse arc keeping the ending with his father's sacrifice. He is also utilized as the narrator for various episodes, explaining the story to the viewers and summarizing some events (including scenes cut for time).  An earlier pitch version of "G-Force" (pre-Fred Ladd) had the character named "Lucas".

In "Eagle Riders", he is renamed to Hunter Harris, and his Bird Style is referred to as "Hawk" rather than that of the Eagle. An episode containing a flashback to the climax of the Red Impulse arc had its dialogue altered to imply that Hunter and his father had a much closer relationship, and that his father had never taken on a secret identity. Hunter also later contracts a wasting disease, as Ken did in Fighter. Unlike Ken, Hunter is said to have had his disease fully cured.

Voice Actors

Katsuji Mori voiced Ken in the original franchise and provides the voice clips for Tatsunoko vs. Capcom, as well as reprising his role in the cameos in the Time Bokan OVA and the 2008 Yatterman series.

However, Ken was voiced by Masaya Onosaka in the 1994 OVA remake.

Ken is voiced by Tomokazu Seki in the Tatsunoko anime hero crossover Infini-T Force.

English Adaptations

  • Casey Kasem voiced him in "Battle of the Planets".
  • Sam Fontana voiced him in "G-Force: Guardians of Space". The rejected pitch version of "G-Force" had him voiced by Don Spalding.
  • Richard Cansino voiced him in "Eagle Riders".
  • Eddie Frierson voiced him in Harmony Gold's original dub of the OVA.
  • Todd Garbeil voiced Ken in U.S. Manga Corps' dub of the "Time Bokan: Royal Revival" OVA.
  • Leraldo Anzaldua voiced Ken in both ADV Films' dub of the original series and Sentai Filmworks' redub of the Gatchaman OVA.


  • Given that the Gatchaman team are modeled after American superheroes in design, the Birdrang is an obvious nod Batman's famous Batarang.
    • Coincidentally, the Birdrang and the Batman Beyond's Batarang share a slightly similar design (collapsible wings and an oblong handle).
  • Robin's Birdarang from the TV series Teen Titans bears an uncanny resemblance to Ken's weapon, save for the red and yellow coloring. This is possibly intentional, as Ciro Nieli, the serial producer of the series is known for referencing classic anime in some television shows he works on.
  • In the earliest plans for the series, Ken's Bird Style was to be the "Great Hawk", not an eagle. His surname was to also be "Hayabusa" (lit. "peregrine falcon").
  • While Ken's mother was never given a name in the original series, the OVA remake revealed her name to be Sayuri Washio.
  • An alternative design for Ken from the original series depicted him wearing a blue jacket and hat, as well as his pants being straight-legged and his shoes being blue sneakers.
