Aquis  ( is an enemy in the シードラ  Seadra ) ? . It is a mass-produced, seahorse-based Sonic the Hedgehog series Badnik model created by Dr. Eggman, which move around in the air.
Based on seahorses, Aquis has a yellow and white metallic body. The head section has white eyes, two sharp antennas and a small, vuvuzela-shaped snout. In the neck hole are two bolts set on each side. On the back side is a row of five back spikes. Unlike real seahorses, these Badniks also has small wing fins, although it is unclear if the Badnik can float because of the wing fins.
There are differences between in-game sprites and artwork illustrations, as the artwork shows Aquis to have sharp a spike at the end of its tail, while in-game sprites show the Badniks having a normal tail like real seahorses do. In
, Aquis' design has been altered with orange back spikes and cyan eyes. However, they do not show having antennas and sharp spikes on their tails.
Sonic Lost World
Sonic the Hedgehog 2
The first appearance of this Badnik was in the 16-bit version of
, where it served as an enemy. This time around, this Badnik is referred to as Sonic the Hedgehog 2 Aquis  (. In this game, the player encounters them in シードラ  Seadra ) ? Oil Ocean Zone.
In gameplay, there can be up to two of these Badniks in the same location. When it sees the player, it starts moving closely forward them and shoots oil projectiles at them. An Aquis does not move away after that, as it floats around the player for while and keeps shooting more projectiles. As such, the player will have difficulties avoiding these Badniks and it is better to keep moving. However after a while, the Aquis starts attacking by moving towards the player and then floating away without stopping. The player is able to destroy these Badniks by
Spin Jumping on them when they do not shoot their projectiles. Also, upon their destruction, they release an Animal.
An unnamed Badnik similar to Aquis appears at
Blue Marine Zone in . These Badniks scuttle through both overworld and underwater sections of the zone and start firing projectiles. However unlike Aquis, if the player destroys Badniks by doing Spin Jump at right time, they don't have Sonic Blast Animals inside them at all.
Sonic Lost World
Wii U/ PC version of , the Aquis can be encountered in a secluded passage near the end of Sonic Lost World Frozen Factory Zone 1. However, instead of shooting oil at the player, they will swoop down from above and use a vacuum attack to steal the player's Rings. Defeating them will release the Rings they stole, along with an Animal.
, and its expansion Sonic Mania , the Aquis appear as enemies. In terms of design, they look exactly like they did in Sonic Mania Plus . In these games, they only appear in Sonic the Hedgehog 2 Oil Ocean Zone.
In gameplay, the Aquis behave just like in their debut game: they float around quickly and shoot projectiles at the player upon spotting them. Also, upon destroying an Aquis, it will release an

Sonic the Comic
The Aquis in
. Sonic the Comic
series published by Sonic the Comic Fleetway Editions, the Aquis are a part of Dr. Robotnik's Badnik army. Depending on the artist, the Aquis' appearance would be altered slightly. They fought Sonic a couple of times early on in the comics.
The Aquis in the
comic series and its spin-offs published by Sonic the Hedgehog Archie Comics, the Aquis are members of the Badnik Horde that appeared during Operation: Clean Sweep. These Badniks patrolled the Oil Ocean Zone.
The Aquis' name is based on a combination of the words "Aqua" and "Equus," the former which means "water" and the latter which is the genus that include horses, which is befitting since the Aquis is based on a seahorse.
In both the Nick Arcade and the
Simon Wai prototype of Sonic the Hedgehog 2, Aquis Badniks have slightly different appearance as having more of a pink color scheme as well. Unlike in the final version of the game, these Badniks also behave more erratically. The Debug Mode object list of Oil Ocean Zone shows a variation of this Badnik that seems to shoot oil balls at Sonic when approached. They are internally known as "seahorse" and "skyhorse", respectively. Aquis' Japanese name, "Seadra", is short for "sea dragon".
