One plus Two makes Sun Vulcan

Taiyo Sentai Sun Vulcan (太陽戦隊サンバルカン Taiyō Sentai San Barukan, translated into English as Solar Squadron Sun Vulcan) is Toei's fifth entry to its Super Sentai series. It was broadcast in February 7, 1981-January 30, 1982 and is the only sentai to serve as a direct sequel to the one prior, Denshi Sentai Denziman. It was Toei’s last series with a Marvel copyright, but again with no Marvel involvement in the production. The theme was air, land, and sea.

This is the first Sentai series to have a combining Robo, Sun Vulcan Robo.
This is the first and only Sentai series where the core team is all-male, though at the time of this series, the three colors of Red, Blue and Yellow were always male whenever used.
This is the first Sentai series to have a core team of less than 5 (3), followed by Abaranger (4).
If you count the Goraigers as their own organization, then Hurricaneger is the only other series to match this feat.
This is the first Sentai series without a Pink Ranger, followed by Liveman, Jetman, Kakuranger, Gaoranger, Hurricaneger, Abaranger, Gekiranger, Go-Onger and Go-Busters.
This is the first Sentai series without a Green or Black Ranger, followed by Gekiranger.
Ryusuke Oowashi (the original VulEagle) was written off the script because his actor was a singer and had to leave to make a new record.
While the title does not suggest any of the traditional Sentai names, it actually is based on a pun that makes it work: the Japanese pronunciation for "Sun" is "San", which is the same as the Japanese word for "Three"; with this the three-man team of Sentai, the pun works perfectly, akin to the usage of "Go" in Sentai names such as Goranger, GoGo-V and Go-Busters.

So yeah, this is birthday art for *spongefox. If I messed up anything on Jessica, I'm all ears.
