Kowl is voiced by Erik Gunden
First seen in the episode “Into Etheria”
Kowl is more than just a pet to the Great Rebellion. He’s part of the family.
There are only a few of Kowl’s species left on Etheria.
Three of the fortunate few were introduced in the series: Kowl himself, a female called Kowla [38] and his cruel cousin Red Eye. [48]
While Kowla helped Kowl open his eyes to the value of freedom (and romance!), Red Eye lent his cunning services to the Horde in an attempt to thwart the Rebellion.
The thing is, Kowl’s species have the ability to read each other’s minds if they possess a selection of another bird’s feathers.
This almost helped the Horde defeat the Rebels, but She-Ra’s quick-thinking put a stop to them.
Kowl’s worth to the Rebellion is proven by his ability to fly at immense speed, as Queen Angella once pointed out. [79]
He has flown to the aid of Adora and others several times [14, 21, 42] and also to warn his friends of impending danger. [27, 51, 66]
However, Kowl is blighted by his biggest weakness – a lack of courage.
This would be apparent in a lot of episodes [01, 
24, 82] and would be the main focus of a few. [43, 48, 52]
Courage and self-esteem have also been tackled with such characters as Madame Razz [43], Peekablue [80], and Spritina [88], but Kowl beats them all off for winner of the most prominent ‘fraidy-cat.
Possibly the only character more cowardly than Kowl to grace the She-Ra series is Sorrowful, but by the time he made his last appearance [82], he had gained all the courage he needed.
Kowl has a well-developed relationship with Bow.
The two appear to have known each other for years and share a clear love/hate relationship (and, as a brief side-note, they were also the first Rebels to be seen on She-Ra).
They would exchange jokingly nasty comments with one another on regular occasions [08, 34, 41], but would never let these quibbles come 
between their friendship.
Finally, a brief note about Kowl’s one-off rivalry with Imp. [43]
The two came close to blows after Imp insulted the rebel bird and then attempted to frame him as a thief.
As one would expect, the truth came out and Imp got more than he bargained for by messing with Kowl – a face full of gooshfruit.
