SO…. here’s the combined form of the toy, Go-Buster Oh. And below is the Japanese video review

Where the Buster Ace blasts away usual Super Sentai conventions to make a truly rad mech that looks and behaves like something out of Armored Core, we thought that this was a beginning of a new direction for Super Sentai mechs. Instead… they out Super Sentai’ed previous Super Sentai by combining into the biggest messes we’ve seen since well… that pile of toys you left on the floor.

All I ask of this world is that we get a SRC of just the Buster Ace and I’ll never ask for anything else ever again.
