Andrew was forced on the run, ditching his suit's power source to avoid being detected. He had to use his gadgets as blunt instruments or regular weapons. He refused to turn himself in or turn to someone else for protection.  Eventually replacing the custom pieces of his suit with other forms of tactical gear he had to adjust.   Especially when he went on the offensive attacking first,, even killing the people in his way.  

From what you pieced together he stumbled upon something during a heist,  a conspiracy or a plan that needed him to be merciless in order to foil it. 

" 2.0, cute." You remarked on his costume when you met up again. He was using all of his training to carry on, everything he picked up in order to survive. " But do you really want me to test it all out on you?" 

He slipped into your car staring coldly. " I'm not here to take a single thing from you. I'm hear to take you..." 

"Your coming with me..." 

You caught up with him in the aftermath of the bloodbath, the limo  seemed like a massacre despite the metahumans inside. He was exhausted after his fight but still ready to fight his way out. " And someone drops into the ring..."

You were tracking the target for weeks but on your surveillance  you heard sounds of a struggle. You found Red X in the backseat, with the bodies in the front moving them out of his way. 

"If it isn't my clean up.."

"Just keep driving.... just keep driving. I used your tools for these weapons.."
