So, "The Blast" is some character you created? Looks like Nightwing mixed with Jean Paul Valley's Azrael.
Yeah, Nightwing was a primary inspiration in 1998 because they shared the same colors (though as stated, the Blast was first inspired by the Scarlet Spider).
At the start of the year, before the DC Relaunch announcement, I decided that the Blast needed a significant change. Since he was constantly Black and Blue since 1998, I decided to be bold and turn bloody red for “Blastpoint”, a symbolic turningpoint for me and my character based on Flashpoint. With the relaunch announcement showing Nightwing as black,red and looking like my other favorite character Batman Beyond, It became clear to me that I should keep the colors for his own relaunch.
I also noticed the Azrael similarity. I had no choice because I also wanted his mask to be different from before and I wanted his character art to be symmetrical so I can flop them.
Similarities to Nightwing, Azrael and Batman Beyond are done on purpose because I’ve always been from the house of the Bat.
