This is the main male character from the Getter Robo Daikessen! PSX video game. In the game you could choose whether to play an original male or female character created for the game. You could also input their names. It's been a while since I played it but if I remember correctly his default name was Akira.

Incidentally you see both pilots in the ending anime movie as shown here (they are in the right hand corner):

Tell me something.. How come Giant Robo and Big-O is short?
In according to SRW statistic, both size is about L...
but.. why short?
And Where`s Mazinkaiser?
Shin Getter?
Nirvash Type-3?
Gunbuster?

by the look of it this is fanart. isn't most fanart based on something though. by the look of it this looks like's Gaiking's outfits to me.

below Nu Gundam and between Shin getter and Mazinger Z...

Huh? From Last to Begin, Episode Final to 1st Episode

this is probably just fanart.

What version of Getter Robo is this as I don't recognize the pilot suit he's wearing (is it meant to be Ryouma?)

Whoah!! What is this!? It`s look cool!!

I think that was Sumeragi`s Belt Button that pop out and hit Stratos`s eye

It's not from any particular SRW game, but it still qualifies for the tag. Also, this is the regular Giganscudo, not the Gan Duro. Note the shields on the arms are still the flat ones from OG1.

what was coming out from Sumeragi?

this can't be srw w coz it has gan duro

Oh... :(
Ok, thank you for answering :D
