Seizer

Shīsa (シーサ) is the fifth and ninth boss that Toad faces in Game B of Round Mode in the Nintendo Entertainment System version of Wario's Woods. Shīsa is a skeleton wearing a hooded robe and carrying a strange book. His overall appearance gives him the appearance of a Grim Reaper like creature.

Wario's Woods
Shīsa makes his first game appearance in the NES version of Wario's Woods where he was a boss character that Toad has to face off against. Shīsa makes his appearance in the forty ninth round and has 14 hit points. He has the power to make two complete rows of enemies fall at a time. He also sports the generic abilities of throwing enemies and re-locating himself to different areas of the stage. If Shīsa is to re-materialise on Toad after re-locating himself, he instantly defeats Toad.

Super Mario-Kun
In the eleventh, twelfth, and thirteenth issues of the Japanese exclusive manga series Super Mario-Kun, Shīsa makes an appearance as a boss character that Mario, Luigi, Toad, Yoshi, and Wanda had to face within the Wario's Woods adaptation in these issues. However, being one of the harder opponents that the group of protagonists had faced, Shīsa easily defeats Mario, Luigi, Yoshi, and Wanda using his powers and nearly claims victory.

Fortunately, Toad, who originally fled the battle due to being frightened by Shīsa's threatening appearance, manages to gather his strength (after seeing his fallen friends) and challenges Shīsa by his lonesome. After a long battle, Toad manages to defeat the Grim Reaper-like boss and claim victory for the heroes.

Name
The origin of Shīsa's name is hard to ascertain. "Shisa" is the name for lion statues found primarily in Okinawa that have the ability to ward off evil spirits. The name may, however, instead be related to the word for a Christian priest, "shisai" (司祭). It is worth noting that the word "shi" (死) means death in Japanese, connecting with Shīsa's Grim Reaper-like appearance.
