Blaster is basically a rip-off of soundwave, but he has a surprisingly better alternate form. Yet, nothing can beat soundwaves tape-cons, like lazerbeak, buzzsaw, ratbat, rumble and frenzy. And nothing can beat soundwave's awesome auto-tune voice. But still, blaster is pretty good, for a rip-off.
About this creation
So here's blaster in his 'boom box' mode.
He's a bit small, but don't forget, so are boom boxes.
Unfortunately, he's only four standard bricks tall.
And here is the original G1 blaster.
To transform him, you first need to pull down his legs.
Then you pull around his shoulder.
Do the same with the other side.
Then you pull down the arm.
And finally, do the same with the other side.
And here we have him in his robot mode.
He's very small, but he gets away with it because of his boom box mode.
Here's a look from the back.
He's only five bricks tall, but you know why.
And here he is battling soundwave. He's the one on the right, for those who don't have a clue who's who.
