I wanted to update Alex's design a bit and got https://www.deviantart.com/katheread to do so.
This is Alex before after his mind is restored and he does a outfit akin to that of B-042.

Admittedly I haven't thought this far ahead yet, but Alex will get his mind back eventually. His new armor is made of the shell that B-042 was originally made out of. He will haven gotten a taste for more modern an advanced weapons and will visit new worlds to get inspiration for them.
The powers of B-042 and ALJE are now part of him. But despite his power increase. Alex will just be happy to be back with his family.
