Seadra is a blue, seahorse-like Pokémon. It has a long snout and a two fin-like ridges curving over either side of its head. Its belly is covered with rough, cream-colored scales. Seadra's lower pectoral fins have sharp, pointed, cream-colored tips that exude venom. It also has a large, coiled tail.
Seadra can swim in any direction while facing forward by rapidly flapping its fins and tail. It catches its prey by spinning its body to create large whirlpools. When its prey is exhausted, Seadra swallows it whole using its long snout. Seadra's venom is toxic enough to induce fainting in humans, but is prized among practitioners of traditional medicine.
Seadra makes its nest by either wriggling between or anchoring itself to branches of coral under the ocean. After a female Seadra gives birth, the male Seadra will take care of the young. It is markedly vicious, and will mercilessly attack those who venture near its nest.
Seadra's first appearance was under the ownership of Fergus and was one of the Pokémon that were captured and cloned by Mewtwo in Mewtwo Strikes Back. The Seadra clone is seen again in Mewtwo Returns.

In Sea Sea Seadra, A Seadra first appeared attacking Bill as he made his way through Viridian Forest. He managed to suck him into a Whirlpool, but he was caught by Yellow with the help of Pika. She released him after she healed him.
Silver had a Seadra as a part of his team which she evolved from Horsea sometime after The Legend where she was given back to him by Green, although she was not shown at the time. During the events Ampharos Amore of the Volume 9, Silver secretly sends Seadra to Gold via trade for his Poliwhirl, triggering Seadra's evolution into Kingdra, upon which she was finally shown attacking Sudobo in a battle between the two trainers during Tyranitar War.
Seadra sleeps after wriggling itself between the branches of coral. Those trying to harvest coral are occasionally stung by this Pokémon's poison barbs if they fail to notice it.
Seadra generates whirlpools by spinning its body. The whirlpools are strong enough to swallow even fishing boats. This Pokémon weakens prey with these currents, then swallows it whole.
The poisonous barbs all over its body are highly valued as ingredients for making traditional herbal medicine. It shows no mercy to anything approaching its nest.

Origin
Seadra is based on a seahorse, though its ability to shoot ink resembles that of a squid. Its category might be a reference to leafy sea dragons, seahorses turning into dragons after a century in Japanese mythology, or the Japanese word for seahorse, which translates as "dragon's child". Its large, spiky, poisonous fins may be inspired by the lion fish.
Name origin
Seadra may be a combination of seahorse and dragon or hydra (a mythological sea creature).
