Kanaloa

Kanaloa (カナロア, Kanaroa) is a giant octopus that belongs to Byro Cracy, a member of the Legion Corps of Zentopia.

Appearance
Kanaloa is a gigantic, purple octopus with several light blue spikes protruding from its head, as well as two large horns extending from its forehead. Despite being an octopus, Kanaloa's tentacles appear clawed at the ends similar to a crayfish's. A series of teal spots mark its forehead. Kanaloa's eyes are perfectly rounded with teal scelera and bright yellow pupils, and just between its eyes is the emblem of the Zentopia Church.

Key of the Starry Sky arc
Kanaloa first appears with its master Byro, listening to Byro as he speaks to it. Later, the two arrive just before Natsu and Sugarboy are about to clash. Byro informs Sugarboy of their original goal and to dispose of anyone who stands in their way.

While Natsu and Sugarboy fight, Kanaloa and Byro leave though they encounter Gildarts Clive along the way. A fight commences between Byro and Gildarts, with Erza assisting Gildarts mid-way. However, after Mary Hughes informs everyone that she has obtained the clock key, the entire Legion Corps leaves, as their mission has just been completed.

After Natsu, Romeo, Lucy and Happy find their clock part, Byro along with Kanaloa appear. Natsu laughs at Byro for riding on an octopus, but Byro tells Natsu to not underestimate Kanaloa, because it belongs to the Legion Corps and is a soldier, as the rest of them. After that a fierce but short fight ensues between Natsu and Kanaloa, since his motion sickness prevents him from fighting after he rides on the creature. However, Lucy later summons Taurus and this gives Natsu the chance to defeat Kanaloa, after she, Romeo and Happy support him with their skills.

Magic & Abilities
Flight: Apparently, Kanaloa is able to jump high distances, thus serving as Byro's transportation. Once in the air, Kanaloa is able to "fly" using its tentacles, in a way reminescent of an octopus swimming underwater.

Corrosive Ink Eject: Like a real octopus, Kanaloa can eject a blackish ink from its mouth, however this being toxic and corrosive enough to melt hard rocks with it.
