Wild is one of the last new characters on the show. He’s a pig in Purgatory and the unknown brother of Hawk.

Meliodas and Ban learn Hawk was born as Mild. And that Wild has missed him very much.

As he watched his baby brother kidnapped by the Demon King many years ago.

Wild fights the Demon King quite admirably but seems to be killed.

But he luckily survived. I was very happy he reunited with Hawk. He really was the best big brother ever.
