As an Exceed, Frosch is a small, long-tailed, green anthropomorphic cat that can stand on its hind legs. Frosch has large, round eyes, each complete with a pair of prominent eyelashes, and rosy cheeks.
The entirety of Frosch's body, aside from its face, is covered by a pink frog-like suit, of which the vast majority is covered by black spots. The suit sports a plain belly, webbed hands, and a hood which forms the frog's head, complete with two beady eyes resting on the hood.
Frosch is happy-go-lucky, has a habit of speaking in the third person, and agrees with other people's opinions, regardless of what they may be. Also, Frosch has a habit of asking questions that others may deem to be redundant, such as when it was scolded by Lector for asking who would win between Orga and Warcry. Frosch is also very fond of Yukino, apparently having a good relationship with her when she was in Sabertooth, and was seen visibly saddened by her excommunication from their guild, and, afterwards, mentioned that it felt lonely. Frosch has a fear of being excommunicated from Sabertooth, but, according to Rogue, Frosch's fears are for naught, as he is there with it.
Frosch loves Rogue, and was very worried when Rogue was being beaten by Jiemma. Frosch is also very outgoing and is willing to put itself in danger to protect the ones it loves, as seen when it ran to where Gajeel and Rogue were fighting, intent on making the "Shadow" leave Rogue's body, and when it arrived, protected Rogue, who would die if the fight continued any further, from Gajeel.
Frosch also has a very good relationship with Lector, and is always, if not with Rogue, in Lector's company. When Lector was "killed" by Jiemma, Frosch was left in a state of total shock. Later, on the final day of the Grand Magic Games, Frosch was very visibly depressed without its friend by its side.
Aera: Like all Exceed, Frosch is able to sprout angelic wings that enable it to fly.
