Devilman vs Getter Robo is mostly a generic team up title. This is a pretty recent title as it was done in 2010, but uses the classic Getter Robo backgroud story of an evil Dinosaur Empire as the villains. For reason never explained Akira and Miki from Devilman show up at the Getter Robo base for an overnight stay. Silene has her own planes, she joins up with the Dinosaur Empire to try and take out both Devilman and Getter Robo.
The most interesting part of this manga is the final battle which include Miki and Michiru getting their own Getter to pilot. Though in the end it doesn't do much, but at least the gave the ladies something to do, other than being damsels in distress. The best part is when the demons merge with the mechasaurus, which leads to some really cool looking designs.
Also, while in the information I could find for this lists Go Nagai as
the author and mentions Dynamic Pro (Nagai's studio) as the artist. I
find it odd that Ken Ishikawa isn't mentioned at all since Getter Robo
was really his baby. The art is Nagai style but looks to be that yes it
was probably done by someone other then him. The faces and a few other things are just kind of off.
I can't say to much about this title. It was short, only one volume. But it was a fun quick read, though pretty insubstantial. It pretty much is a by the books team up title, checking off all the tropes as it goes along.
