SirenStriker

"Yuu-Mou-Ka-Kan!"

- summoning announcement

SirenStriker (サイレンストライカー) is a specialized Trigger Machine modeled after an armored tank.

Overview
SirenStriker was housed inside VictoryStriker in a smaller form, but when it emerged it returned to normal VS Vehicle size. Its default form can fire yellow explosive rounds from its giant cannon. Its Attack Mode unfolds plough-like extensions that can be used like a forklift to throw opponents. In addition, the missile launchers by the cannon's side activate. When SirenStriker's Keisatsu Boost is activated onto a person, it grants them the "Super" armor based on SirenStriker itself (i.e. Lupin X transforms into Super Lupin X). By holding onto the shoulder handles the shoulder cannons can fire laser blasts. By charging up, a finisher is initiated. For Super Lupin X it activates the Super Superior Strike, five golden steampunk-esque rockets.

History
During the fight over VictoryStriker, VIctoryStriker was under Jarnake Saucer's control. As the Lupinrangers were inside the Striker trying to figure out how to retake control of it, LupinRed found out that another VS Vehicle was hidden inside VictoryStriker. SirenStriker then emerged from Victory's inner "hangar", and interrupts Jarnake's control. Later on Jarnake enlarges, so the Lupinrangers form Siren LupinKaiser and defeat him.

Siren LupinKaiser
"Complete! Siren LupinKaiser!"

- post-combination announcement

Siren LupinKaiser (サイレンルパンカイザー) is the combination of SirenStriker, Trigger Machine Splash, Magic Dial Fighter, and GoodStriker. The combination is very powerful. It can use all the cannons on SirenStriker and throw opponents back with the ploughs. SIrenStriker seems to influence the other VS Vehicles in the combination, as it allows Splash to fire quick-drying cement. Magic can also enlarge and rotate for a physical hit.

It finisher is Good Striker: Blow em to Smithereens Cannon (グッドストライカー 撃ち砕いちまえキャノン), where Siren LupinKaiser blasts laser fire from Magic's baton, Splash's water cannon, and SirenStriker's cannons, missile launchers, & ploughs to destroy the enemy.

Siren LupinKaiser Strong
Siren LupinKaiser Strong (サイレンルパンカイザーストロング) is an illusion of LupinKaiser Magic, with Trigger Machines Crane and Drill replacing Trigger Machine Splash. It was used to test Dugon Manattee's knowledge in LupinKaiser, which he managed to identify by pointing out on their lack of said Trigger Machines, as all actual forms of LupinKaisers vanished and the illusion reveals the real Siren LupinKaiser.
