Kamen Rider Delta

The 3rd rider introduced to Kamen Rider 555 (i skipped Kaixa cause I'm having issues with reference.

Kamen Rider Delta (Δ) is the ultimate gear when compared to Faiz and Kaixa, it was used by at least 5 different students from Ryuseiji Tutor (some main characters included ie Kusaka, Takumi)

The Delta Gear's first actual user was Kitazaki the Dragon Orphenoc of Lucky Clover, he got bored with the gear after some time and stopped using it.

Since then it landed in the hands of a Ryuseiji student and mostly 3rd party character: Mihara Shuji, however Delta would be a pretty useless rider despite how cool he looks because despite being stronger than Faiz and Kaixa, Mihara as Delta needed to be saved by Faiz and in the final battle when he tried to help Faiz and Kaixa he was defeated quickly.

It really sucks that such an awesome gear was so underused and poorly misused through the whole rest of the series after its introduction.

See? Neither link is Mihara's henshin or rider kick (Lucifer's Hammer, such a badass name)
I was going to keep the BG white but decided to do it the red of his visor and then make his triangle in white.
BTW, ALL the other Faiz riders (Faiz, Kaixa, Psyga and Orga) have cellphone style henshin devices but Delta has a pistol lookin thing that he uses voice commands on.
