|This article is about a/an character in Kamen Rider Ex-Aid.|
- For the character from Kamen Rider Gaim, see Lock Dealer Sid; for the character from Kamen Rider (Skyrider), see Keitarō Shido; for the character from Kamen Rider Amazons, see Makoto Shido.
Shido (シド) is the synthesizer player of the rock band Neironzu, also featuring Sora Iwamoto and Shishido, whom hosted the Level 40 Gatton Bugster. He accuses Shishido of copying off his name, despite "Shishido" being his bandmate's real name.
While auditioning to preform the theme song for Genm Corp.'s next game, his bandmate Sora was injured by falling stage equipment, sending her to Seito University Hospital. As she was in recovery, he and Shishido started arguing, accidentally triggering all three of their stress and causing Gatton Level 40 to manifest from inside him alongside Motors Level 20 and Kaiden Level 40 from his bandmates. The Bugsters fought Ex-Aid Double Action Gamer Level XX and ShiShi Red, but Gatton escaped with Kaiden.
They later targeted Seito Stadium, where the band shared the dream to play at. Gatton was intercepted by Brave Hunter Quest Gamer Level 5 Full Dragon, and was soon defeated alongside the other Bugsters. The bandmates then apologized for their earlier behavior.
